Fuel cells (7) |Links:
- theoretical limits to battery capacity
- Interesting thesis on what power and energy densities we can expect in future.
- Advanced Battery Technology: NEC Develops Fastest Rechargeable Battery
- Short article on a battery that charges in 30 seconds.
- NEC high energy density battery development
- A very high energy-density development from NEC
- ECS Home Page
- The electrochemical society will probably have info on all the cutting-edge battery developments.
- Solar Cell Doubles as Battery
- Interesting article: Researchers developed a solar cell with integrated ultracapacitor to store the generated charge, making for more efficient everyday use. Not directly useful, maybe, but who knows?
- Maxwell Technologies ultracapacitor vs batteries
- The basics: Ultracapacitors can charge and discharge very quickly, but energy density is very low compared to batteries. Also, the voltage drops to a too low level long before the energy is depleted.
- Toshiba preps minute-charge 'miracle' battery | The Register
- Toshiba has developed a Lithium-Ion battery capable of being charged to 80 per cent of its full capacity in under 60 seconds. Filling it up takes just "a few more minutes", the company boasted today.
- Lithium Sulfur
- Sion Power Corporation is developing this technology, which promises double the energy density of Lipos.
