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 won’t 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.
