Hybrids, Electrics: Nano Power?

摘要

Want evidence that electric cars could soon be competing with hybrids? Consider what nan-otechnology adds to lithium-on batteries in terms of better battery life, power density and charge times. Those benefits-up to 10 times longer cycle life, fivefold power gains and five-minute charge times-are beginning to be incorporated in Black & Decker Corp. 's line of DeWALT tools. Those performance levels have been validated by Motorola and government labs, says the battery vendor, Watertown, Mass.-based A123Systems.
