Full EV and CHP is here

This means the full Electric Car is now within easy reach. All it needs is charging points around. Use a specifically designed engine on a generator set, like a small rotary Atkinson cycle, and use a large bank of these batteries and the combustion engine will rarely cut in.
They claim the discharge is the same as supercapacitors. I would rather have supercapacitors with a high energy density storage than a battery. Supercapacitors do not wear out, they are more efficient as there is no state change inefficiencies when charging or discharging.
Other applications? Planes of course. CHP (cogen) in homes? Roof mounted PV cells can charge them up and use the energy later.
Mass production will get the prices down. They could be retrofitted to extising hybrid cars to transform them
------- Toshiba International Corporation, January 27, 2010 - Toshiba proudly announces that it has established US-based sales and technical support for its new product, the Super Charge Ion Battery, SCiBT. This nano-based breakthrough lithium technology is noted for its rapid charging capability of 90% charge in less than 5 minutes, long life of more than 10 years even at rapid charge rates, and excellent safety performance. The SCiBT product line will be supported out of the Toshiba International Corporation headquarters in Houston, Texas and the SCiBT team will focus on business development activities, battery pack design, prototyping, assembly, technical support, and service. The SCiBT battery technology offers numerous performance advantages that make it an ideal solution for many of today's toughest energy storage challenges. . Inherently Safe - Advanced Lithium Chemistry Based on Nano-Technology Prevents Thermal Runaway Even Under Extreme Physical Duress . Fast Charge Rates - Capable of Full Recharge in < 10 Minutes, 90% in < 5 Minutes . Superior life - Minimal Capacity Loss, Even After 6,000 Rapid Charge-Discharge Cycles . Greater Usable Capacity - Up to 85% Usable Capacity Without Compromising Cycle Life . High Output Performance - Equivalent Discharge Rates to those of Ultra-Capacitors . Superb Low-Temperature Performance - Excels at Temperatures as Low as -30C . Proven Production - Produced on a State-of-the-Art Automated Production Line
SCiBT cells comprising the battery packs will be supplied from Toshiba's state-of-the-art automated production line in the Saku Factory located in Nagano, Japan. Initial market development activities in the US will focus on automotive HEV/PHEV/EV, industrial lift trucks, smart grid/grid storage, medical equipment, wind and solar power, scooters, and UPS market segments. Toshiba currently has two battery pack offerings commercially available, a 12 V, 4.2 Ah pack and a 24 V, 4.2 Ah pack. Both offerings are based on Toshiba's 2.4 V, 4.2 Ah cells and include Toshiba's proprietary battery management system, which ensures optimum performance and safety. Additional packs are under development.

Within easy reach of those who can afford the very high prices. It's likely the batteries will be so expensive they are rented rather than bought. Making any savings in fuel only running costs rather pointless.
But then you never have had an concept of value for money - just belive every advert you read.

I recall seeing some published research about 18 months ago, that I think was the basis for this advance.
It was a small change in Li-ion chemistry (one that had been disregarded many years earlier because the voltage per cell was slightly lower) - but, new research showed that the chemical-structure mechanisms that impeded current flow during charging, were very much reduced.
At the time, the researchers pointed out how similar it was to existing manufacturing processes, and the tooling costs should be much more modest than other process changes.
However - there's still other problems to overcome - fast charging (e.g. 10 minutes) of vehicle-sized batteries requires very large currents, something around 1000A at 400V.
That's both a problem in terms of infrastructure development, and if it proves popular - electricity demands on the producers.
Does anyone know if this advance is Toshiba's property, or public research?

Toshibas. Charging points could have banks of supercapacitors dug into the ground - like petrol tanks are, to charge up slowly from the grid, store and sell off to cars. The same as the antiquated Victorian water distribution system we have that serves us, because people store water in tanks and use it when needed, topping the tank up slowly.
The first batch is never cheap. If the engines on generator sets in series-hybrid, like the Chevy Volt, can be made smaller and cheaper and wheel hub motors are used eliminating differentials and shafts and CV joints, then the higher battery cost can be absorbed. Expect to see full EVs in matter of years - if the auto giants will allow it. Do a Google on "who killed the electric car?" On Youtube in 9 sections. Enlightening. Worth watching as they crushed 800 GM EV1s, including a turbine driven generator series-hybrid EV1, that did 120mpg. Then Bush states that hydrogen and fuel cells is the way, which takes oil to produce, lots of it and the fuel cells do not work.
The US FAA is killing the electric aeroplane, outlawing it. As the final drive of the Chevy Volt (Vx Ampera) is mechanically disconnected. This entails that the engine on the generator set can be a more efficient engine that optimises as a constant speed or narrow speed range. Preferable engines that few reciprocating parts to give smoothness and quietness. Auxiliary engines with rotary valves were used in Sorts Sunderland Flying Boats in WW2. The Rolls Royce Grecy engine, the successor to the Merlin Spitfire engine, provided an amazing amount of HP in such a small 2-stroke package - abandoned as jet planes were the future. Engines were made and tested and it worked. http://en.wikipedia.org/wiki/Rolls-Royce_Crecy
What looks promising, but requiring development is the Rotary Atkinson Cycle engine. Smooth,small and quiet: http://en.wikipedia.org/wiki/Atkinson_cycle#Rotary_Atkinson-cycle_engine
Now, this can apply to a two engined plane. Small very high power-weight ration electric motors turning props on the wings with a smooth, optimum tuned, constant speed combustion engine turning a generator with a battery buffer in the fuselage. The generator set can be positioned for optimum weight balance. The overall setup will save overall weight. Like a The batteries can be used a reserve to get the plane 40 or 50 miles. If the engine fails the batteries take you down safely.
Or for full backup, and electric assist. Have a small rotary Atkinson cycle engine turning the prop, that has an electric motor on the shaft. The electric motor assists in take off and if the combustion engine fails it reverts to battery electric power. Having an electric assist mean the combustion engine need not be so big as it is used for cruising and topping up the battery.

Storing AC? Now that's a breakthrough. Or simply add the electronics to convert to DC and back again. Or equip the car to accept either. With two sets of plugs and sockets. Then of course hope the capacitors have had time to charge before needed. Great with all those cars chasing an inadequate supply.

Happy to be a realistic plantpot who doesn't just believe every single advert. Got a new Prius yet? They've finally made one that just about does what it claims. Quite a good car apart from the looks.

Now I may have got this wrong, but I understood that there was only one ore source of lithium in the world and it's not infinitely large.
