Sample:
Nanotube Ultracapacitors
* MIT researchers introduce nanotech battery - Nanotube ultracapacitors would store energy on atomic level, providing what is said to be the first technologically significant and economically viable alternative to conventional batteries in more than 200 years. (PESN; Feb. 9, 2006)
* Discovery Could Increase Power of Ultracapacitors - MIT laboratories have announced that they can improve ultracapacitors by swapping in carbon nanotubes which would increase the ability to store energy and increase the surface area of electrodes, making them comparable to batteries used in hybrids. (TreeHugger; Feb. 16, 2006)
* Carbon nanotubes set to improve performance of ultracapacitors - Analysis shows that the utilization of a matrix of vertically aligned CNTs as electrode structure, can lead to an ultracapacitor characterized by a power density greater than 100kW/kg (three orders of magnitude higher than batteries), a lifetime longer than 300,000 cycles, and an energy density higher than 60Wh/kg. (MIT Laboratory for Electromagnetic and Electronic Systems)
Vanadium
* Top 100:
Vanadium Redox Batteries - Low cost, low environmental impact battery that has a superior deep cycling life and can be mechanically refueled in minutes. Suitable for green energy storage, backup power, electric vehicles and utility load leveling / peak shaving. (PESWiki)
Lithium
* 75 miles for a 5 minute rechargeable car - Fuji Heavy Industries, the maker of Subaru brand vehicles, announced that it will release the R1e electric mini car by 2010, and that the vehicle will begin road tests in Japan this year. The R1e uses a lithium-ion battery can be recharged to 90% of capacity in five minutes. (WorldChanging; Aug. 21, 2005)
A123Systems releases new Lithium-ion battery
Utilizing nanoscale electrode technology, the battery lasts 10x as long, has 5X power gain, charges 90% capacity in five minutes. First batteries will be sold to Black & Decker for their... (OSEN; Nov. 2, 2005) (MIT Technology Review; May 19, 2006)
* Toshiba's New Rechargeable Lithium-Ion Battery Recharges in Only One Minute - A breakthrough technology applied to the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store vast amount of lithium ions, without causing any deterioration in the electrode. (Toshiba.com; March 29, 2005)

They list the battery used in my scooters:
Silicone
* Silicone batteries by Guineng - Using silicate salt is used as electrolyte, Guineng batteries "have enormous and durable power and are pollution free." They have high capacity, high current output, rapid recharge time, low temperature performance, long life span, and environment-friendliness.
They even have one that runs on pee pee:
Urine-Powered Battery - Singapore physicists create first paper battery that generates electricity from urine. Technology is an ideal match for cheap, disposable healthcare test-kits. (PESN; Aug. 16, 2005)
