since gets to the guy the you watching dw news from berlin of next, how the battery in your phone could be used to store renewable energy that's on planted a after a short break. i'm like, look good. i'll be back with more news at the beginning. the next the learn shannon with the word winning offer is available. language learning. jasmine has never been sent. can you see what old card players have to do with the production? here's a hands on the

real media. watch now on youtube. this random assortment of stuff is all you need to build an actual battery the let's see if it works. so now there's just a moment of truth if i could make these cables like will one. now this is of course, super simple basic way it works is not that different from the batteries powering uh, phones, laptops, tooth brushes, and vacuum cleaners, cortez and even electric costs. all these things use a special type of battery coating lithium ion and they've gotten so goods that

we're now building huge ones all over the world. and this may be the key to solving one of the biggest challenges about time the on the 1st let's back up a little at 18. hundreds of themed tele and sciences. other sandro voltage vents, the world's 1st batch or a cold level take pile. now our little coins back is a replica of volts pile. we've got 5 central instead of copper. and then we've got these little watches that updated with zinc. and in the middle we've called bits of paper that ourselves and vinegar. the reason this works of the chemical reactions that are happening here, very simply speaking, electronics so negatively charged particles, good freed up on losing cans and compounds is ready to receive. once you connected with the cable of the electron stop flowing from the sink to the corporate. well now you've got electricity. a chemical reactions in here, reversible someone's found no more and you electrons to go over the battery expense

. just like it happens with your typical household battery that you throw away after using, for example, the ones and your results. first, rechargeable battery was invented in 1859 by french visits as gospel once it used to lead. and so for an assets, if you hooked it up to an outside source of electricity, the chemical reactions got reversed, ventured he got charged again. throughout the year is different battery types for different purposes were invented. and then in the early 19 seventy's, the hill of our story, the lithium ion battery 1st appeared on the scene. the person to come up with the idea for it was surprisingly assigned to this that the exxon mobil. then the oil giant was worried, the world was going to run out of oil, so it was scrambling to find alternatives. the battery he developed was rechargeable and used lithium metal that's particularly reactive. so it could set free and lots of energy. but this original battery didn't make it big. video went

through a couple of hands though, improved. it's before the regents solely based on the concept them to a products and it starts mess producing with the of my own batteries 1st using it in the camcorders with a new handicapped c or was it from there? the technology became a standard and everything from laptops to power tools. they can be charged at least a few 100 times and pack a lot of energy into a small space. all this meant lithium, ion battery, sweat, perfect to power, personal electronics. and it wasn't long until another industry also recognized that potential, the automaker saw the opportunity and then they invest that a lot of money. this is evelyn a story who's an analyst in the energy storage team of research from bluebook any? yes, the automakers are basically the leaders on pioneers and making learning batteries cheaper and better to see more batteries also relatively lights and don't lose much of that charge when they're not used under together. they're great to power

electric cos. so as more electric cars are sold, more of the team, i own batteries are produced, and that's made them a significantly cheaper since 2010, the price for lithium ion battery is, has dropped by 90 percent. just to put that into perspective, making one for a test level why in 2010 would have cost $83000.00, making the call prohibitively expensive. today the battery only costs around $8000.00, and this drop in price makes them attractive to use for something even bigger than the cost. storing renewable energy. this console one of the biggest problems the world is facing right now. we know that burning fossil fuels as heating up the pilot. we also know that generating energy from the wind and some 1000 bucks. so one of the key functionalities of energy storage and the grid is shifting the energy from the time where we have a lot of energy generated to time times other others later in the day where,

where we don't. and that's where that's where it's coming in. the middle of the day when there's lots of sunshine and your solar panels are working well charged. and once the sun has gone down, they use the electricity stored in here to power the grid. and to do the same as your wind. right now the main way to store energy is through something called pumped hydro, to pump water up into the lake on the hill. and there's lots of tricity drawn down through a turbine. when there is. the problem is though, you can't build this any way, whereas you can put these pretty much anywhere as low as batch reprises, keep folding that quickly becoming the number one energy storage technology or the demand. but to the, at the runs a competitive solution. this is make out the all works in the energy storage team of new when a private company that produces renewable energy in 2017, they billed dispatcher in the south of australia, which at the time was the biggest lithium ion battery in the world. it was

a way to show to the, to the world that's human, but frequently a cost effective solution to, to supply in buttons agreed. that's it. the group's case, this has been extended spots back then the batch of me to deliver a 100 megawatts of the equivalent of a smaller gas power plant. for up to one hour and 15 minutes. we've been boosting battery storage and mic breaking speed of a sense. in 2017, we build 1.8 gigawatts of storage batteries. 2023. we built 41.5 gigawatts. mess of jump in just a few years. they can factory now is this one in california which can still 17 times more energy than the one in australia. and even though it's located in the us, the driving force behind the growth of good storage batteries charge instead of point the most. and also producing the most of the mind batteries in the world. china had identified early the value and the use cases 49 batteries. so they

spent a long time, many, many years, developing the technology, scaling up on faction. and also it's an industry that have is received a lot of support from, from the government. so with that is we just keep pumping out, let's say mind batteries and the energy system will pretty much change all by itself. well, unfortunately, not to make batteries. we need to buy in minerals and just like mining anything this has environmental and social consequences. need to keep those in check. one big step in the right direction is that there's no more cobalt and whatever the theme i am the batteries binding of which was often linked to child labor cobalt free best results are cheaper than this. fix this, the, my a batteries can blow up much. this is happening a lot less than used to risk manufacturers are working to make the cells. there's another challenge that's how to solve though, and that's to do with the storage duration. that's the time it takes the battery to

fully discharge of full power. if you think about your phone, that'd be the time you can play with that before it goes from fully charged to flats. for a new phone that will be around 10 hours of effort, which for rick batteries at the tense develop as designed them based on the specific locations needs, ends in a way that can make money from using needs the length of the storage duration somewhere up to 4 hours and one big reason for that is because the sun and the peak production of a solar energy loss about 4 hours. so you can charge for about 4 hours and then discharge for 4 hours. that means you have enough energy stored when the sun sets until people go to bed. the thing is though, depending on where you live, there might be days or even weeks with very little sun and wind, which means we will also have to cover stretches longer than 4 hours. technically speaking, that's not a big problem. imagine this, that's where you can discharge 4 hours worth of energy. or you could just add

another one of the same size and you'd have 8 hours and you can just keep adding capacity like that. but what else do that is a question of money left because it keeps the twice as much a, a better assessment, but frequent those on the site. so it's on most selective things. the cost of the project also progresses. wouldn't get to sell the full 8 hours. all that often goes for hours usually is enough to building bigger batteries. just in case doesn't really make sense for them. there are other solutions that scale better, so become cheaper, the more storage you've built into them. what option is to store energy in gravity? another in heat hooked up both of them in a separate video. but it's questionable whether these can quickly become much cheap enough to feel more than to reach the market. because so much money and so much time has been devoted to losing my own daughters to make them that cheap. it's hard for other technologies to compete. you have it at the needs to shut them still rich

. it's 28121424. i was, well, you to my own, but 3 week period and we'd be the most competitive solution, which isn't to say there won't be any space for other solutions, particularly for store energy for weeks and months. that's over the next few years, building lots and lots of good storage batteries already gets us pretty far to become carbon neutral. it says we need to triple renewable energy capacity by 2030 . and to accommodate for all this flexible image phone scene times most storage batteries by then. and we have today, this may seem like a daunting task in 2 decades of innovation. you might have about series of strides, tested and ready to just need to keep building the if you heard of any big batteries getting billed, where you live, let us know the comments. don't forget to hit subscribe for more videos like this one. the
