7:30 am
turkish governments, all sorts of gibbs, but only if the crime is addressed in the power of attorney to takes responsibility for his actions. guardians of trees, stock october 28th on d. w. the energy saving nights, smartphones, computers, electric cars, wind turbines, we need metals for all of these things. but mining them is not just energy intensive. it's homes, the environments is recycling and alternative. or could we source rule materials from space that and move coming up the kind of welcome to tomorrow. today dw science program
7:31 am
lithium is commonly used in batteries that power electric vehicles. the largest metal on us is abundantly phones, but only in small concentrations and mining lithium is complex, expensive tom sold to the environment. and even when does this seem is contains, within the batteries, it's still dangerous. explosions and fires caused by lithium ion batteries, after shorting damage or overheating time. and again, we see how dangerous thing can be the best one in the world is searching for originally for new battery technology at the helm homes institute in the german city, a form researchers are trying to find a replacement from just as an energy source and quickly now
7:32 am
decides things this side of via yeah, we don't have model, i'll tell you because it's expect that the demand for batteries is going to grow very, very strongly. and we are expecting a 4600 percent increased by 2013. yeah. yeah, that's, that's who comes with this, the toys that, that means we have to give back to the technology a white material base we all, since we have to bring abundant for sheet and easily recyclable materials into play . going to go with the side, the bottom of the screen. the rise and demand for battery storage is huge. with wind and solar power expansion, one of the main drivers. then there is the electro mobility sector. by 2045, they're expected to be 30000000 electric vehicles in germany alone. that will need lithium for their batteries. misfire mazda for han listing may be a bundle,
7:33 am
but it can't be mind quickly enough to meet the demands completely. that means we have to turn to materials that are widely available, but still do a very good job. and the ones that go to the inner structure of the lithium ion battery contains 3 problem matic materials. a positive terminal of cobalt, a negative terminal of graphite, and the lithium itself, which moves back and forth between the poles to load and discharge the battery. cobalt is points and it's and is now off and replaced by lithium iron phosphate to create what's known in the industry as an l. f. p. battery chinese firm b, y, d e has developed a new battery design because our technology still requires a lot of space and the battery cells understand that these are, you know, have larger units in place of the small flattery sales office, which is
7:34 am
a bit bigger than a chocolate bar and they simply need less packaging on the site. as a result, it could accommodate much more storage materials and the actual overall bottles, because i'm using lithium high end chemistry in this space. saving battery design gives an amazing 1000 kilometers of range. the new l f. p. chemistry offers a much reduced range, but the batteries have other advantages. they don't require cobalt and are also 30 percent cheaper, as well as being much safer. in the case of lithium batteries, the nail puncture test shows why these batteries are so dangerous. the resulting short circuit causes an explosion and a fire that isn't easily put out. all of the batteries aren't completely different . here the nail test causes only an increase in temperature also. now if the
7:35 am
batteries will in the future, be able to be recharged $3.00 to $5000.00 times a charging stations. that's 10 times as much as current rechargeable batteries. but the range with a full battery is only 60 percent done. of a lithium ion battery charging and cold weather also causes problems. the but the biggest helps yet in battery development are for sodium ion technology. it replaces the batteries, lithium ions with sodium ions. this change in battery chemistry, also allows cobalt and graphite terminals to be replaced with more sustainable materials. but the sodium ion batteries are quite a bit heavier. you have not. everything needs to be as light as a cell phone battery, for example, in huge wind energy storage facilities,
7:36 am
such as these in australia, weight is not an issue. the sodium is produced from ford and every table salt, which is readily available in large quantities. sodium am batteries have a shorter range on a single charge, but they charge faster and are almost full again after just 15 minutes. another advantage, unlike almost all other batteries, they still deliver at 90 percent of their power in freezing temperatures. and even in the classic internal combustion engine, the starter batteries can be replaced by sodium batteries and within their toxic chemistry. after all, the global market for starter batteries is as large as that for lithium ion battery . then this is default timidly. the question is, how quickly are all the raw materials on the market?
7:37 am
how quickly will they be available and can they be installed for the production capacities are being prepared at the moment? that's where everyone is actually very well positioned in the next 30 years. but whether sodium or lithium, without natural resources, we wouldn't have any new batteries at all. heavy industries depend on the natural source from real materials. if the supply is caught, production lines everywhere trying to help. the benefit, see, or scarcity of rule materials, determines the market price, germany impulse missiles from all over the world. this has geologists on the hunt for new sources, headquartered in berlin, the german minerals resorts agency. darrow, for short trades, wrote materials source all over the world to companies on behalf of the german government, desks and white heidi, this customer i offer, or that contains cobalt from the democratic republic of congo. lex, if it's the helper, is used for electricity from inability to renewable,
7:38 am
energy technology for power, transmission and cobalt. i need for batteries and an invite to the envelope. see amanda alvarez. he is concerned about germany. israel materials supplies isn't and women school placement currently facing a lot of challenges for care all over the world. supply chains have been disrupted, or even broken under the cottage degree and russia situation, of course, funds. there a develops new concepts to keep politicians and industry leaders up to speed on risk so that impact supply market prices. they focus on the so called mega trends, like the move to electro mobility and we got trends and mega trends. the 1st and foremost global phenomena on kind of among listings wistar guessing on technology such as the lithium ion battery, a mobility, electrolysis for hydrogen production and rule material demand. and the future payments include sign down in this type of energy transition. some key role
7:39 am
materials are hard to procure, it's becoming increasingly expensive. this means that geologists, us to act early, to warn others of possible supply bottlenecks and price fluctuations prepared dossiers. and studies like this one with cobalt sure, under this green lane is great for showing us how the cobalt price is more than double in the last 2 years on the london metal exchange. on one side. this is because of increased demand on the other because of the problems to supply chains that we have had to deal with in the past few years. and that's young. cobalt is important for lithium ion battery. 6 in 202170 percent of the global market share was mind in the democratic republic of congo, which is being played for decades by political and social unrest. number 2 on the cobalt market is russia. market share around 4 percent,
7:40 am
but risk price is good sky, real good, further and deliveries may not be many of us. the adults and retail german firms to diversify, to move away from supply from only one country big for an item, and then one by a. so you know, is it a roll? material is crazy cool. you look for a potential replacement, some more it so you try to replace stays materials without those, if possible. i know most of the places that's that's not always possible. special metals like rear x are needed urgently to build wind turbines, clear air, our phones worldwide, so never endure farm, only income phones, the separation and upgrading is done with the aid of assets. a large amount of toxic overburden is produced in the process of china's rhetoric demand
7:41 am
amongst 86 percent of the global supply. and in the middle of that make sense of, of the lucas is a traveling through countries. then we try to get this rounded as possible a picture of the whole 2nd 3rd lesson. we publish this information, which we also include in our consultancy service. and there are also shares this information with non governmental organizations, such as berlin based power shift, which campaigns against global inequality concerning human rights and environmental issues. you can always add this at 1st. we can cover everything that are 25 of us in the team. and yours are very important and bringing to light abuses and 2nd countries, and that helps us recognize developments in air leak. and it's also important for us studies and analysis for the reason. it's an important collaboration because the energy revolution can only truly be clean when the raw materials are procured fairly unsustainably red, it's a chemical elements from the 9 to 9th. through the elements atrium is
7:42 am
a bad as well. right? it's is a misleading name. as the 9th, the red, no, all the colors range from stone to silver and quick to thomas when expose to oxygen will react quickly when they come into contact with water. one of the many applications is in the production of permanent magnets, which are also used in wind turbines. at the beginning of 2023, a huge deposit of red, as was discovered in sweden, and untapped minium tons is thought to be in the ground. north of the arctic circle, but to this day, no permission has been granted to mind them. the known method, some best separation and upgrading would home the environment. they've been mining iron or for many years in cuba, luna. and the mine is considered one of the world's largest. if the head of the state online a company has his way, a new mind most to be added. exploration has detected more than a 1000000 tons of rare earth science. and 4 to 5 is that we have ongoing expiration
7:43 am
activities in this, the pulse that which means that for us it's open. it's not roles. they don't actually know how big it is. but what we know today is by far the law just the pulse it off, already ease in your that might help your up fulfill its goal of becoming climate neutral by 2050. as anyone building wind turbines for e car batteries needs rare earth. after a press conference in the tunnels of the que roonan lines, sweden's minister of finance is thinking big fan. yeah. hard and installed to store. yeah. so sweet and has a proud history of mine and have them installed, but i'm did some good, but also a bright future ahead should come out there. and so many of the so called rare or it's are critical in going green and meeting are ambitious climate targets. what
7:44 am
the heck stuff that came up until now. europe has relied on imports and china dominates the industry according to estimates by us geologist. the deposits in china are 40 times larger than those in sweden. environmental groups hope that the deposits in northern europe will be mind in a greater way than in asia. a came outstanding on may have transitioning to renewable energy electron mobility for going to us made those have to dependent on china say, you know, the 30000000 in going on. they are going to be anything if we can 1000000 our own re or ass and europe implementing better methods in claimant protection. and this find is a real game changer and game changer. but it will take perseverance to reach that turning point and also the goodwill of the so many people who have lived up north since time immemorial. the area that they want to develop, run straight through the land of the reindeer herders. and additionally, official approval and construction of
7:45 am
a new mind could take 5 to 10 years instead of mining new role materials, could we recycle those that have already been processed and are in circulation? it's a feasible option, even when it comes to lithium, ion battery is used in electric vehicles. the batteries have to be shredded and the fundamental materials separates it. but how does this work in detail? let's get the lego to understand who has a few and i, in box of these get recycled. it's often involves smelting. so essentially she took them until the melt. but this uses lots of energy, creates toxic emissions, and you lose some of the materials. that's why companies are coming up with new ways to recycle that you want to have as much as we can with high value materials that are, have taken a lot of effort to get over the ground. we want to use those carefully and as many times as we can, this is canal felt the chief commercial officer at life cycle,
7:46 am
lithium, ion battery recycling company from canada. we basically come up with a process designed specifically for this to have high recovery rates of the material. in the 1st stage, what we call or spoke is a mechanical process that breaks down the batteries and separate some of the fundamental materials. very, very simply speaking, this is what happens. the batteries are shredded weeks of matters in a non toxic solution. this is important because it prevents them from catching fire . and then the worst case blowing up then materials like plastic copper and l. u minium are separated from what the industry calls the black mass. this contains valuable materials like cobalt, nickel, and lithium. the 2nd app part of the process is the hub. and this is really a bas folks hydro metallurgy or when chemistry process to process black mass into battery gaming materials. what this means is that different chemicals get added to
7:47 am
the black mass which lead sholtes different elements. these chemicals either make their way into the final product, or are we used in the process? so this doesn't actually produce any waste water. you end up with the black mass separated into a single components like lithium, cobalt and nickel. so the end goal is that as we pull them out of the batteries, we're putting them backed into new batteries and that hasn't been, she didn't achieved yet at a high scale there's, there's elements of, of it around the world. but we want to help to, to continue to drive that forward. it's hard to keep track of exactly so many lithium ion bought to these already get recycled mainly because they're often exported. but it's already happening more and more, especially in asia, where most of them are also produced. and this volumes of spent factories, girl, it will also make even more financial sense to recycle them. this is the in the,
7:48 am
i do worry that we, we hope that there is no verb in new jersey to keep our auto renew of materials that they already produce. could be, we used to be a problem. let us read why i want to find out more about room materials or are you curious about something else from the world of science, send us a voice message or a video. if we answer your questions on the show, you even get a small price as a thank you. this week, a view question is from, can this do so done yet in columbia? why our researchers more interested in march than in the moon? the mars is our outer next door neighbor. it's more of it is further away from the sun than the earth. mars is the only other planet in our solar system that humans could conceivably live on. that makes it especially
7:49 am
interesting. maurice has a comparable day and night for them to hers. a day on mars is just 37 minutes longer than a day on our planet. it's shaped our by over them's the days and nights are both 14 earth days long. with extreme temperature swings between daytime and nighttime, because unlike earth and mars, the moon has no atmosphere to regulate the warmth and the coldness. mars and earth also have similar like conditions as the sunsets on both plan would show. on top of that beer, it's axis is inclined almost as strongly as mars's all the shared commonalities mean that there atmosphere is have similar characteristics. in comparative climate research that makes mars is atmosphere
7:50 am
a model of the earth's atmosphere. the moon would be of no use. the earth's atmosphere is primarily made of nitrogen and oxygen. it's the only planet in the solar system with liquid water on its surface. there was also water on mars 3 and a half 1000000000 years ago. has these river valley show, then the red tenants climate was more conducive to life and its atmosphere denser. but mars has lost a large part of its atlas fear, the a constant flow of particles from the sun. lowes parts of mars's upper atmosphere into space, the earth's atmosphere is largely protected against this by its magnetic fields. today, mars is atmosphere is only $100.00 the density of earth. and the world that was once conducive to a life has turned into a dry icy desert. water can only exist on the red planet as ice or vapor. there's
7:51 am
even an ice covering the surface of its poles. and in the ground, there are rich reserves of important resources for mand outposts. in early 2022. europe's ex, on march trace gas, orbiter discovered vast reserves of water ice. under the 5 is my re now is the so called grand canyon of mars. the simulations are already in use to calculate whether it would be possible to set up an artificial magnetic field between mars and the sun to make the red sign it more conducive to life. again, air pressure and temperature would rise until the carbon dioxide ice at the north pole mills and sparks of greenhouse effect that turns the ground dice into rivers and sees it would be possible, at least in syria. now back to the topic of rule materials,
7:52 am
there is yet another potential source for us to explore in space. sounds far out, but in syria it seems possible. some celestial bodies that passed by us on untapped gold mines nature. in 2015, an asteroid fit passed close to our planet, was estimated to contain more platinum than has ever been money done. or the 14th asteroid. 16 psyche, a metal which world sent to be worth $700.00 quintillion dollars. a mining asteroids scene just fear radical for a long time because space travel was just too expensive, but that's changing a seat on a space. x walk, it is 3 times cheaper than it was. i'm the space shuttle. this had started a new gold rush in 2012 larry page, the co founder of google put his wealth behind the company planetary resources, which during the race to mine, asteroids in 2017, nasa announced it would pay
7:53 am
a visit to psyche. this is mindy open stanton who has, who has a psyche mission an important thing he mentioned that i'm running is a pure science mission. but also the program is not about asteroid mining. it could help lay the groundwork for such missions in the future. crazy as it sounds, mining asteroids might not only be feasible, but also much more sustainable than mining on earth. and it actually turns out that the answers seems to be yes. andrea's height is a research here who has actually crunch the numbers. the estimates that the rocket fuel needed to go and bring back one kilogram of platinum from an asteroid would release 150 kilograms of c o 2 into the earth's atmosphere. terrestrial mining with generate 40000 kilograms. so asteroid mining could be hundreds of times less
7:54 am
polluting. essentially, the main reason is there's almost no other substance you can mine and which you can generate step much. greenhouse gases outsourcing, mining to space would decrease pollution on earth. but there's some economic problem in terms of sustainability. again, when in terms of economics, it's not profitable yet. for me, if you mine like 5 times of the cost of them, you have on this right now, it means that the market price is willing, needs the crash. you can sell it as a, as a much lower price. which means as you diminishing your profit margin, so you operate in your interest put to the loss. and that makes so it's very unattractive for investors. carbon taxes and new technologies could change this equation, but it would still take several years for space wanting to become profitable. investors do not want to wait that long. levinsky is company failed to raise enough
7:55 am
funds, forcing it to a band, and it's goal of mining asteroids. planetary resources didn't succeed in their ultimate goal to to mine asteroids. but i think it's succeeded in a lot of ways of the steps to get the business case doesn't quite yet close, but we couldn't make it get there. we can find a way, and i think it is in some ways be in the future times because the kansas, it's been our history as long as we've been able to track it from backwards acumen are. the new inventions can make space mine in economical. just a few decades ago, the very technology you're using to watch this video seemed impossible. today. we can use satellites to being the internet everywhere on the planet. 101520 years. a lot can happen. one day mining on earth may be obsolete a bit like using candles to light your room. and that was

7:59 am
multitasking these, the modern methods. because if we do too much, we had it all wrong. we messed things up, risking brain damage. so let's stop this self sabotage, humans and multitasking watch. now on youtube, v. w documentary, the limitless freedom of the online young north koreans fled to south korea, where they realized their dreams of becoming social media. to detect is we posted a bit knives under kim john, but then they disappeared without warning. need to reach to us as a north korean propaganda video was happens from north korea, which love starts october 25th on d w the
