Toyota's New Solid-State Battery Could Make Its Way To Cars By 2020 (techcrunch.com)
According to the Wall Street Journal, Toyota is in production engineering for a solid state battery, which uses a solid electrolyte instead of the conventional semi-liquid version used in today's lithium-ion batteries. The company said it aims to put the new tech in production electric vehicles as early as 2020. TechCrunch reports: The improved battery technology would make it possible to create smaller, more lightweight lithium-ion batteries for use in EVs, that could also potentially boost the total charge capacity and result in longer-range vehicles. Another improvement for this type of battery would be longer overall usable life, which would make it possible to both use the vehicles they're installed in for longer, and add potential for product recycling and alternative post-vehicle life (some companies are already looking into putting EV batteries into use in home and commercial energy storage, for example).
Cool story, Bro. Except the reason we don't have solid electrolyte batteries is because the blow themselves to smithereens (along with everything around them) if you attempt to charge them at low temperature. They also suffer from serious sinusoidal deplanaration if their cardinal grammeters are not absolutely perfectly synchronized. To top it all off, a solid electrolyte battery can't even convert energy through the modial interaction between magnetoreluctance and capacitive duractance, leaving us with the time honored yet ancient tradition of using the relative motion of conductors and fluxes.
"Blah blah _could_ " yay I can stop reading now!
I don't think this word means what you think it means.
Wow Darrell, are you a detective?

The molten salt battery was supposed to be the next big battery technology, until people realised you had to keep them at ~300C or they stop working.

Great, another AC troll on the site. The encabulation technology that resolves the thermal and deplanaration issue has be around since WW2. In 1962 a series of discoveries by GE enabled them to create the turboencabulator, the predecessor to the modern microencabulator. And really, magnetoreluctance? Magnetoconstrictors are practically naturally occurring. Be gone, foul beast!
I swear it's like half the people on the internet don't have a clue about what they are talking about!
Anons need not reply. Questions end with a question mark.
Tesla sells actual electric cars that people get in a waiting list years in advance to buy.
GM sells actual electric cars that people generally yawn at.
Toyota: Our lab-scale battery is gonna be a big hit in 2020!
Solid state batteries are no real magic. It just means that you're using a solid electrolyte rather than a liquid one plus a membrane. They offer some nice benefits (such as resistance to dendrite punctures), but they hardly change the world on their own. They're a popular choice for working towards lithium-air batteries, which would be revolutionary, but there's no way anyone (including Toyota) is going to be mass-producing mature lithium-air batteries in 2020.
But anyway... if you're not going to make EVs, I guess you can still make press releases about hypothetical EVs. Seems to be a popular alternative these days.
And for the record... energy density really isn't the issue; Tesla has shown that you can get quite good range even with today's batteries without having your vehicles be excessively heavy (Model S, a bit over 2 tonnes; Model 3, a bit under). Cost per kilowatt hour is the issue. Tesla is reportedly at $190/kWh now and thinks they'll be at $100/kWh in a few years. But ideally you want even lower than that.
So, apart from that, how was the play, Mrs. Lincoln?
Is this an elaborate ruse? I still can't decide.
It's the battery tech ... Goodenough? Get it? Eh? Damn crickets, drowning out my applause.
What is the charge time? Biggest problem with electric cars is the fact that it takes HOURS to recharge. Even Tesla's super-charger takes at least an hour to fully charge the small capacity batteries.
While the tech is an improvement, without a 5 to 10 min to full charge, the EV are still a hard sale (ignoring current cost).
Disclaimer: I drive a Chevy Volt 2017 ... so please spare me the usual BS accusation of being anti-EV.
After they spent millions and partnered with Tesla to develop an electric RAV-4 they discontinued it even though it meant paying a penalty in California. My bet is that some exec got himself a private island in the Caribbean, courtesy of your neighborhood oil cartel. I do not expect any innovation from Toyota in the EV department, other than to encumber the technology with patents.
as early as 2020.
I don't get used to those kind of years being "early". They always seem far in the distant future.
Rome taught me patience and assiduous application to detail. Virtues which temper the boldness of great, general views.
In terms of number of battery units produced, Tesla and GM are roundoff error compared to Toyota.
Several issues with your "analysis". 1) The Tesla Model S is a $70-100K car so not exactly and apples to apples comparison 2) The cars you are comparing have been on the market for 6 years or less versus 20 years for the Prius. Of course cumulative sales will be bigger for the Prius. Do you know how many Prius were sold in the first 5 years on the market worldwide? 81,700. That means that both the Volt and the Model S outsold the Prius over the first several years of their availability. 3) The Bolt has been on the market for a year. Are you seriously going to compare cumulative sales of a vehicle that has been on the market for a year to one that has been on the market for 20?
That tells you that there's something seriously wrong with the scalability of their production.
Not even remotely. I design manufacturing production systems for a living. Tesla scaling production to deliver cars more quickly would be a substantial cost with no obvious benefit to Tesla either short or long term. The reason they haven't done it isn't that they cannot do it but because they have chosen not to do it. As long as customers are willing to wait for delivery it would be enormously stupid of Tesla to devote that much capital to upgrading assembly lines and supply chains. There is no evidence to suggest that faster production would result in enough marginal extra sales to be worth the expense. They need to produce cars fast enough to keep their customers happy but any faster is wasting money. So far Tesla customers clearly are ok with waiting a bit.
(If you want to know what the problem is, Tesla relies on selling ZEV credits to other automakers to keep from going bankrupt. But other automakers only need a certain number of ZEV credits each year to comply with CARB regulations. So Tesla has to be careful not to produce too many ZEVs lest they cause the price of ZEV credits to plummet due to oversupply.
Wrong again. Tesla is not throttling production for that reason and they certainly aren't calibrating it to demand for emissions credits. That would not be a sustainable business model and Elon Musk certainly knows that. The reason Tesla isn't profitable and why they produce at the rate they do is much simpler. They simply lack the economies of scale enjoyed by major auto firms. That fact alone is why you haven't seen a major new car company in decades. It's hard to achieve minimum efficient scale in the auto industry, particularly with a wildly non-traditional product offering. They have to reinvest all their capital (and then some) into building the company. Production lines to make cars are enormously expensive. Companies like Ford and GM and Toyota have had years to develop the scale and balance sheets necessary to bankroll such investments. Tesla is still a small young company with a weak balance sheet and it will take time to get to where the major auto makers are now.
Pretty much all small companies have the same problem including mine. My company makes auto parts and we could easily bring in enough people and machines to deliver products to our customers in a few days. But the expense would be enormous and we would immediately become uncompetitive on price. We also could produce products ahead of time and inventory them but that means we tie up vast amounts of capital in inventory and storage. Producing products faster than your customers demand them is wasteful, expensive, and stupid.
This is great news! We are headed towards non-toy status for EV's! Extended range will make them feasible for real world commuting.
I want one.
The use of the term "solid state" here bothers me.
I've always understood "solid state" to mean "no moving parts". By that definition all batteries are solid state! And no, the presence of a liquid electrolyte does not count as a moving part. Nothing about the liquid is required to move or designed to move.
This could be resolved by simply removing the word "state". These are "solid batteries", not "solid state batteries". Much clearer, IMO.
ruse, yes. https://en.wikipedia.org/wiki/...
The answer is graphene super capacitors. This technology is coming very quickly. Being able to charge your car in 30s; not replacing your entire battery set for 1/2 the cost of a new car every five years; and not having to worry about freezing/cooking your batteries is a game changer. Until then, its just that same old shit.
