Posted on 10/23/2011 9:57:17 PM PDT by aquila48
Toyota Motor has developed a secondary electric car battery that can last up to 1,000 km per charge, the Nihon Keizai Shimbun reported Monday. That is five times the energy storage capacity of existing batteries.
Toyota came up with the prototype in collaboration with the Tokyo Institute of Technology and the High Energy Accelerator Research Organization. The new battery is based on a solid core and its simplified structure means it does not require fire-retardant materials. It eliminates the disadvantages of lithium-ion batteries, which are based on an easily heatable and combustible liquid core.
Toyota plans to improve the battery and commercialize it sometime in...

Get it to 1000 miles and it’ll be suitable for vacation travel.
Wow, now all we need is a heap of COAL the size of Nevada, and the EPA to go “F” itself so we can burn the coal to make electricity!
You still have to modify your household electric just to charge it up.
What will it cost?
Have to wonder what the recharge time is, if it takes that long to discharge.
It's a new technology, and cost will depend on wide adoption, mass production, and competition.
At first I expect it will be cost-prohibitive for all but the high-end. But it will plummet if it works and is adopted.
Consider: In the mid 1990's, flash memory was typically $200 for 1MB, and only crazy rich people used it. Today it's around $20 for 16GB, and everybody has a couple "thumb drives" laying around.
That's a cost reduction of more than 150,000:1 in only 15 years! Heck, even 10 years ago, no one in their right mind would have predicted that Flash would become so inexpensive. It's all about competition and mass production, once something is widely adopted.
The "early adopters" always pay a high premium.
it all depends on how much heat is generated during charging. If the internal resistance is low, then not much heat, and you can charge it at much higher currents -- that means "faster".
Part of the problem with the present generation of batteries is that they generate a lot of heat when being charged, and you dare not let them overheat, so you are limited in how fast you can charge them.
When fuel taxes dry up they’ll supertax electricity.
That is all a reasonable analysis but those are not the only factors involved in its basic price once they have played their part. Materials and production costs will have some lower limits and will affect how widely it is adopted as well.
For a first approximation if it holds five times the charge it will take five times longer to “fill” at the same current.
The present limit is the current available in your household supply - the 30A 220v dryer socket equivalent.
So if the Leaf needs 8 hours for a full charge the new battery will need about 40 hours for a full, but bigger, charge.
A lot more charging infrastructure will be needed - invest in copper...:^)
5x40 is 200 miles, the other 400 miles is from the primary gas engine.
Ditto. Now how long will charge last running an AC in summer or heater in winter?
True, but there’s a limit to how much current a household can draw, which could be the true limiting factor to recharge time. 1,000KM is a lot of drive time hours, so it has to hold a lot of KWH.
“Memory” is another factor. IF the new battery is not affected by that affliction, then one could drive 4 hours; stop for an hour to eat, while leaving it on a charger to partially recharge. Or, could replenish a partially depleted battery nightly, after the daily commute.
If it IS so afflicted, then trips would need to carefully planned so that it runs out of juice where you wish to spend the night, and are able to give it full charge.
Isn’t 1000 KM about 12 and a half miles? Maybe my calculator is broken.
A “secondary battery” is a rechargable battery.
A “primary battery” is a non-rechargable, such as ‘regular’ flashlight & lantern batteries.
It isn’t talking about a hybrid.
One thing for certain; you wont be charging it on 120VAC house hold current. You have to put in to a battery more than you will take out of it.
You have to put in to a battery more Kilowatt Hours than you will take out of it to push your car down the road. A battery that can store that much power will need to have at least a 220VAC power supply to charge the battery in a reasonable amount of time. No wimpy lamp cord charger is going to charge this monster.
Unless that is sarcasm, 1000KM comes to just over 620 miles.
If it wasn’t sarcasm, it still comes to just over 620 miles.
1000 km is about 620 miles.
I recharged an alkaline battery using a car battery. It could only be connected for a few seconds. Even at that it got hot. But, what was a dead battery before had enough juice to power a radio again. Figured it was too dangerous to do so only tried it a coulpe of times.
Im guessing the 12 volt car battery was too much too quick for an alkaline battery which is why it got too hot to touch based on the explanation you offered in your post.
LOL. I must have forgotten to carry the 8.
“Isnt 1000 KM about 12 and a half miles? Maybe my calculator is broken.”
How on earth did you come up with that number? How about 600 miles.
Maybe for one person and a small cat providing they had no luggage.
Pretty plain Jane vanilla , but for the money suits my needs just fine.
My abacus is missing some beads. Obviously they are the important ones.
Unless E-cat works, and then copper is going to be the most common metal on earth in the future.
If both of them pan out, it would be totally awesome. Cheap energy and a convenient way to move it around.
It is still a hybrid and over 2/3rds of it’s range is still from gas - all of it unless you can plug it in somewhere and wait for the charge to trickle in.
The story is about the B-A-T-T-E-R-Y, not a C-A-R.
The BATTERY is a new type of rechargeable ("secondary") battery that has much greater capacity than current battery types.
This has NOTHING to do with an engine, gasoline or otherwise.
It may very well be installed in future hybrids, but that is a moot point to this article/discussion.
Unless E-cat works, and then copper is going to be the most common metal on earth in the future.
Not to worry, even IF e-cat works, the anti nuke people will be ALL over it.
Sounds like they're talking about cars to me.
Does Toyota have a non-hybrid, all electric, car nobody knows about? ....that travels 120 miles per charge?
If so, please share the link.
More importantly, can one of these be used in a cellphone?
1000KM = 621.4 Miles
If this new battery suffers from significant memory effect, it will be useless for transportation applications. Let us hope it does not.
Too many structural changes required to provide adequate leg room and a steering column in a cellphone.
That 1000 km/621 miles range happens to be the approximate range of a VW TDI Diesel, and the TDI only takes 10 minutes to “recharge”.
A new and improved coal powered car!
Too bad 0bama wants to put coal out of business, making electricity “neccessarily skyrocket”.
And cell phone contracts continue to rise along witht the cost of hearing aides to name a few...
More than 4 cars but just one will work great in a flashlight! ;-)
1000 miles is beyond what the majority of gasoline cars can do. The real question is how much acceleration it offers.
perhaps you are thinking centimeters
Unfortunately, it’s only 621 miles (1000 km). If this new battery is for a hybrid with a smaller gas engine than the Prius then the government-subsidized Chevy Volt sales are going to get worse. If, however, this battery is for a fully-electric vehicle, it will be a game-changer. Fleet sales may become more viable.
Definitely an improvement, but think of all the other things in your vehicle that would also have to run off that battery and thus reduce the mileage. It is unavoidable to need headlights, heaters, defrosters and windshield wipers while driving. Most drivers would not be too likely to give up air conditioning, the stereo system or power windows (especially if you want to avoid using the air conditioning). Batteries also do not perform well when the temperatures are below freezing or above 100 degrees. That 1000km range might be theoretically possible under ideal conditions like driving in daylight, over flat roads, with no wind and 70 degree temperatures, but in real world conditions could I trust that battery to take me on vacation?
Charge time? How much $ for a full charge? I haven’t seen many comparative reports for electric vehicles and corresponding electric bill increases.
When we're discussing a 40-60K expense after a price decrease, the comparison to a $200 first generation flash drive don't necessarily add up to making this a viable purchase.
I have not seen any in depth analysis as to whether or not our electrical grid in this country can truly sustain a massive fleet of civilian electric vehicles. Seems to me we need to address that first before progress in this arena can be made.
As I see it now, there's no "durable value" in promoting electric vehicles to civilian consumers outside of novelty.
Maybe after the larger issue of energy is thoroughly addressed.
That's still a greater range than typical for current cars. My Camry gets about 450 (+/- 20) miles on a full tank.
In the case of a hybrid/electric quite a bit less.
Yes, but gasoline cars can be refueled in five minutes. I have been known to drive well over 600 miles a day on the way to a vacation spot. I can drive from Columbus to Panama City Beach today in 12 hours with a total of 15 minutes in fuel stops. With a 600 mile electric, I'd have to stop in Montgomery for the night and waste a vacation day...in each direction.
All that heat is wasted energy, reducing the efficiency of the whole process. So a battery that charges with low heat would not only be safer, it would be a lot more efficient.
Found an excellent blog on the effects of cold weather on electric cars. And this is a pro-electric car site.
They say it is likely that really cold weather, MN/MI/MT type, will cut range by 50% or more. Also cuts power proportionately. Climbing in the mountains will also burn juice like crazy. In cold weather you might have trouble even climbing at a reasonable speed.
The possible consequences of a car running out of juice in extremely cold weather in a remote area might be interesting. In the Chinese sense.
