Toyota says new electric car battery could offer 10x the capacity

Toyota may not be at the forefront of electric or plug-in hybrid vehicle technology, but the Japanese automaker announced on Tuesday that it has developed a new technology that will greatly improve the storage capacity of its next-generation lithium-ion batteries.
Although Toyota is keeping mum on the technical details, the improvement stems from the production of single crystals of lithium cobalt oxide. Toyota jointly developed the new lithium-ion technology with Japan’s Tohoku University, according to Japan’s Nikkei newspaper.
Toyota failed to reveal how much more powerful the new lithium-ion batteries will be compared to today’s crop of lithium-ion batteries, but Japan’s Nikkei business daily speculates the breakthrough could net a ten-fold improvement in battery performance – potentially setting the stage for electric vehicles with a range of 1,000 miles. Additionally, the new technology is said to weigh less and take up less space than lithium-ion batteries currently under development.
It remains to be seen when the new technology will be available in a production car, but Toyota has often stated it would wait on electric and mass-produced plug-in hybrids until battery technology became more viable. If the new technology pans out, Toyota could have it to market by the middle of next-decade.

Uh huh, ten fold? Weren’t these the same people who thought the Insight would get 70+ MPG? That’s more than awesome if it’s true, but I’m skeptical at best.

1000 miles sounds too good to be true, I’m skeptical. Once companies break the 300 mile range with EV’s, they will really start to take off.

Sounds like the kind of breakthrough that will cost more than the entire drivetrain on a high end sports car. I predict it only being in high-end electric vehicles until it gets widely accepted, as long as it comes out ahead of the other new battery technologies that are sure to rival it.
They don’t list any cons of this new technology, something every type of battery has. On that note, I’m interested to know how significant the battery fade effect is on these electric cars. When a laptop battery can be down to 80% of it’s life in a year and a half, it makes one wonder how many miles a 2011 Chevy Volt will be able to go on electric power in 2015.

Lets get real, at some point there will be a breakthrough or at least advance in technology that will make electric car usable. I don’t like it anymore then the rest of you guys, but I doubt battery “science” will be stagnant for another 50 years as it was with acceptance of internal combustion engine. In the beginning of last century, there were electric cars, albeit for ladies.
In Montreal I was on a tour of port in electric boat. It used as much electricity as 2 hair dryers, according to the guide. The boat could have about 20 people and battery lasts all day.

It’s my experience that tour guides lie about as much as they possibly can get away with. Besides, hair dryers can trip a 15A breaker. At 110V, using Ohm’s Law, P=I*E, that boat would be drawing at least 3.3 kW, which translates to about 4.5 hp. So, in reality the tour guide wasn’t stating an impressive fact, he was telling you how poorly powered the boat was. In what I’ve seen in the current market, an American sedan needs at least 100 hp.
That being said, i totally agree with the advancement of battery technology increasing. With the widespread use of rechargeable batteries, new technologies can become economically viable much quicker. And if you subscribe to the concept of the technological singularity, these technologies should continue on an exponential growth path in the future.

Where did you guys get this high cost from? I see nothing in the article here.
Anyways this is great news. If true the electric car is now feasible. If the Volt can get 40 miles and this is 10x then that is 400 miles of range. Probably satisfy 80% of the public as their main vehicle, not just a commuter. Of course the 1000 miles above is for current electric cars which are glorified golf carts. Now we can look at normal vehicles that have a decent range.
And those that want/need extended range a Volt type vehicle with a much cheaper range extender engine would work.

Borat, go try that BS on some other group of people who don’t know you nearly as well as we do. You were at a bar getting a lap dance and while I’m sure there might have been something to do with a motorboat the only water involved was in the Scotch.

The high cost was complete speculation on my part. The production of single crystal metals tends to be quite an expensive process. This is why jet engines are so expensive, as their turbine blades are made of single crystal metal for increased strength with no increase in mass.

Johnny, I found Jesus (well I admit that this is bills!t off the bat). But I learned from you not to waste my hard earned money on Scotch in the bar, since in the bar scotch, like mother Earth, is mostly (85%) water.
But Mrs. wanted to take a boat tour of Montreal and we took the smallest boat, which was powered like vibrator (but was very quiet and did not vibrate). I dunnno, maybe fish liked it.

skyaficionado: the battery fade on the volt will be exceptionally low because they are not using the entire capacity of the battery. by limiting the amount of the batteries capacity that you use you can minimize battery fade. in reality the volts programming will limit the battery to cycling between 50 and 90%(or whatever they determine to be the optimal numbers for their battery). However, if people hack the software they’ll probly be able to get close to 100 miles on a charge, but after a year they’ll start to experience battery fade(and those people will blame GM for making bad product).
if Toyota can do what they say then that’s great, but I have this feeling the effect is more like a 10% increase than a ten fold increase. if it were indeed ten fold they’d be throwing all the money they could get their hands on at it to finish development first and patent the technology for obvious reasons.

did they also solve cold fusion and find a cure for cancer while they were at it? this seems a bit outlandish of a claim, but even if it’s just an incremental advancement over current batteries it’s welcomed…
i’m not as doom and gloom as some of y’all over the upcoming wave of EVs…i used to draw sketches of electric sports cars as a kid…imagine a super aero tear-shaped pod where the driver sits and arms stretching out from that pod to reach each of the four corners of the cars footprint, with electric motors at each wheel…if the motors are compact enough, you can really play around with the design of a car and move away from the whole big ass engine/transmission space conundrum…but that’s all very much the fictional dreaming of a 10 year old boy talkin’ there…

Leftwing, do you remember the SunRaycer? As weird as that thing was, it was amazing for it’s time. That was my first introduction to the world of EVs, and we’ve made massive strides since then.

The sunraycer was GM’s winner at the electric competition. What was amazing was all the colleges that designed/built the same type of vehicles in the following years.

Fletch first off what you mean to say when they all reach at least 300 Miles or More on a Charge then yes electric will take off. The only company I know that has stated over 100 Miles is Tesla. The Roadster goes 220 miles on a charge and the S Sedan is said to have a Range of 300 Miles.
SO if it were to say give Tesla’s car a Ten Fold Increase were not talking just 1000 miles on a charge were talking 3000 miles on a charge!
But this is still Lithium Ion. eventually a new Nano Substance of Ultra Capacitor will hold an even greater range perhaps 10,000 miles on a charge then their are applications for airplaces with that hardiness built into a battery.

I’m fairly certain that if they can get 3000 miles or more out of a charge they will take it down to maybe about 1500 miles and make the battery maybe 40% as big. I say 40% and not 50% because presumably the weight savings from the lighter battery will add to the range of a charge. Add to that the smaller battery will allow them to reduce the entry price of the vehicle.
No matter because till its on the road it is all vaporware.

Setting the stage for 1,000 miles is not the same as attaining 1,000 miles. I definitely would like to see EVs with that kind of range. Will it add to the charge time, though? Something like this will definitely change the landscape and mindset of road trips. Hotels may offer free charging with a room rental or something.
Whatever Toyota does with this, I hope they make it nice. It would be a shame to ruin such good technology by wrapping it in newspaper like the Camry and Prius. Something funky, perhaps with a similar style to the original iQ concept (not that hideous yellow thing that keeps popping up, but the original white one with the purple interior) would be fitting. Or imagine a Sienna EV. I would be interested in that.

… my question is, where did they get the 10X capacity from?
Hmm… a business magazine is speculating an outrageous figure. Doesn’t that spell figures.. for that magazines sales?
I’m just pointing out there’s no proof to that claim.

Samintosh I would not be willing to give everything over to Toyota there are Plenty of Great Ideas all over the world coming to Fruition. soon just like Toyota. IF they can’t produce it and we can’t see it ; then it does’nt exist yet ok. But a littel company called EESTOR in Texas May Trumph what Toyota is doing. Plus their are countless other startups doing the same thing. I mean with all the concentration being done on electric then why can people focus on even more important issues like a cure for cancer or even Warp Drive Engines

Bull****. This is a wild-ass guess by non-technical people trying to get some readers for their ****ty writing.
Bankruptcy2009, shut the hell up. You don’t know anything. The ability to use a capacitor as a battery has been tried and failed for the last 30 Yeats by universities across the world. If someone finally gets it to work in the lab in a few decades, it’ll be years before it’s cheap enough for us to use it over Li-Ion.
But keep discounting current technology with your bull**** pipedream comments. You’re right, nuclear fission is not the future, nuclear FUSION is! Nevermind the fact that we can’t get more energy out of the system than we put in it. Moron.
