Toyota Plans Revolutionary Solid State Battery for 2021

this video is brought to you by omaze hi welcome to another episode of cold fusion electric cars are positioned for a revolution but in pursuit of more range more performance and faster charging times there's still room for improvement the answer could lie in a technology called solid-state batteries even though solid-state batteries have been studied since the 1950s and meaningfully built since 2011 by the bola company the technology still hasn't broken through on a large scale yet as you'll soon see there's a lot of good reasons for solar state batteries to take over such as much faster charging times a higher energy density but there's also some challenges in today's episode you'll see how toyota may have finally cracked the code we'll take a look at what the automaker plans to do and the pros and cons of the battery technology you are watching cold fusion tv toyota has been researching solid state batteries since 2012 and in 2020 they announced a prototype car using the technology that will be revealed this year if you've seen my toyota documentary you'd know that they've been built on a history of innovation throughout the 20th century in fact toyota has over a thousand patents involving solid-state batteries when you combine this with a 19.2 billion dollar investment from the japanese government that includes funds for domestic work on solid-state batteries a breakthrough was bound to happen so firstly how does the technology work simply put solid-state batteries use a solid electrolyte as opposed to a liquid or polymer gel found in current lithium-ion batteries they function broadly like regular batteries using cathodes and anodes separated by an electrolyte that allows charged ions to pass through it while discharging power oxidation occurs at the anode to create compounds with free-flowing electrons these electrons deliver electrical energy the compounds at the cathode gain electrons and thus store power when the battery is charged the process is reversed solid-state batteries offer a greater energy density anywhere from two to eight times a regular battery all while having the same weight as well as lower risks of fire on the point of fire less safety measures are needed so more space can be dedicated to packing in more power the heat generated inside a solid state battery is 70 to 80 percent less than a regular battery the technology also avoids toxic materials found in current batteries faster charging longer cycle life and higher voltages are all additional advantages [Music] so what do we know about this new battery from toyota toyota claims that its newly developed battery can enable a maximum ev range of 500 kilometers and a charging time from zero to a hundred percent of just 10 minutes and they say this is quote all with minimal safety concerns end quote the company adds that the new batteries provide double the range of what would have been possible with a traditional lithium-ion battery with no compromising on interior space the reports are also saying that this solid-state battery car will be an suv built on the existing e-tng a platform the new suv is expected to debut in 2021 but only in prototype form the full production version should be revealed in about 2023 or 2024 and this isn't just some pie in the sky thing on the manufacturing front the ball is already rolling japanese auto material makers are rushing to set up the infrastructure to supply automakers mitsui mining will start up a pilot facility that will make solid electrolytes for the batteries the production site will be able to produce dozens of tons of solid electrolytes annually starting next year enough to fulfill orders for prototypes so i know what you're thinking this all sounds too good to be true doesn't it if solid state batteries are so good why aren't we seeing them everywhere so before we get ahead of ourselves let's take a look at some problems with the technology [Music] number one the cost traditionally solid state batteries are very expensive to produce in 2012 one single 20 amp hour battery cost 100 000 us dollars to produce to give you an idea an electric car would need a thousand of these expensive batteries to run but for now it seems that toyota and other players have overcome the cost hurdle if they're aiming for a production solid state car in the next five years number two temperature performance solid state batteries are known to have questionable performance in cold temperatures so their long-term durability has a question mark we'll have to see if toyota has gotten around this issue i have little doubt that they would have otherwise they would be facing lawsuits in the future i'd imagine number three damage from dendrite formation solid state batteries traditionally have a problem when charging and discharging and this problem is the formation of dendrites these are needle-like structures that form on the anode as it charges as time goes on these structures grow and damage the battery however solutions to this problem have been worked out by researchers since 2018 as it stands other automotive manufacturers are looking to use solid-state batteries nissan and volkswagen are two such companies the latter has its site set on commencing battery production as early as 2025 in partnership with a company called quantum scape in 2021 the quantum scape team remarks that they've resolved all of the core challenges that have plagued solid-state batteries in the past such as incredibly short lifetimes and a slow charging rate the thing that sets them apart and the interesting thing is they actually have the hard data to prove it according to their testing their cell can charge from 0 to 80 capacity in 15 minutes and retains more than 80 of its capacity after 800 charging cycles it's non-combustible and has a volumetric density of more than a thousand watts per liter which is nearly double the energy density of the best lithium ion cells the key for them was a flexible ceramic separator that sits between the cathode and the anode it's also worth noting that this company just didn't come from nowhere the quantum scape team took 10 years and 300 million dollars of r d before coming across this discovery uh what exactly have you achieved or announced and with this breakthrough on the solid state battery front and when will it start to get produced the solid-state battery has been something that's been pursued for probably 45 years since the mid-70s but no one has been able to make a solid-state electrolyte which is the material through which lithium-ions move that's what we have finally achieved and the results that we showed last week demonstrated that we could actually run these batteries under real world operating conditions the fundamental technology itself though has been run by our automotive customers in their labs so we know the technology works i'd say this is very encouraging but as always we should take it with a grain of salt and it's not just the automobile industry that sees the potential of solid-state batteries researchers at mit have created a phone battery that can last three days they've also solved a lot of the common problems that's associated with the new battery technology most of you have also probably heard about samsung's solid-state battery efforts their experimental battery achieved 900 watt hours per liter and over a thousand charge cycles this equates to a car with about 500 miles of range so to me it seems that after decades of work and no progress solid state battery tech will finally get its stay in the next five years in addition to all of this regular liquid lithium-ion batteries have fallen by 88 in the past decade basically another positive driving force for the electric revolution before we wrap up the video i just want to give a quick shout out to today's sponsor omaze if you've ever wanted to donate money to a good cause but also have a chance to win something big today i'm partnering with omaze to make that happen omaze is offering you the chance to win a house in florida or one million dollars in cash one winner will also take home a brand new tesla model 3 with taxes and shipping included it's the dual motor model with 300 miles or 480 kilometers in range when you enter the fund received from the giveaway will help children's miracle network hospitals they're building a state-of-the-art epilepsy monitoring unit it's going to provide life-changing care for kids of all ages and this is for a broad range of neurological disorders including epilepsy to enter simply go to the link below so toyota has yet to specify exactly when we'll be seeing the new battery but it's scheduled for this year i think it would be so interesting to see if they've actually achieved what's been promised for the past 60 years and i'll definitely be keeping an eye out for it this comes during the news that norway has become the first country to sell more electric cars than petrol cars at 54 in 2020 electric cars beat out petrol diesel and hybrid engines combined it's a specific example but it shows that electric cars are on the move with solid state batteries seeming on the horizon it might be the final piece of the puzzle to push electric cars truly mainstream if you want to see how toyota started and learn about their size i've done a documentary on it it's one of the most popular videos on this channel so be sure to check it out so that just about wraps up the end of the video i want to thank you guys for watching if you did like this video and want to see anything on technology business or history be sure to subscribe to cold fusion next time we'll be continuing our story on intel my name is tagogo and you've been watching cold fusion and i'll catch you again soon for the next video cheers guys have a good one cold fusion it's me thinking [Music] you

If I remember the video correctly, the cars won't be actually made until 2025 or around then. They'll just demo a prototype or something this year.

Progress is good but the title may be misleading in making some think solid state battery cars will be ready this year.

​

Now, will this battery mean we can have much better phone batteries this decade?
