However this is just their power density battery - trying to pack a big punch from a small size battery for power tools and hybrid batteries. Each kilogram of battery can dish out 4 horsepower, which means an A123 battery capable of dishing out the same 21kW that the Prius pack does would only weigh 7 kg!!
BUT.... this is only the first of a series of batteries to come from A123 using their nanotech material. What I can't wait for is their energy density battery, which they have said will also be revealed in 2006. If it's anything near or above 200 Wh/kg, but with the same safety and cycle life as the M1, then it's game over for the whole fuel cell idea and possibly even gasoline too. Bring it on!!   |
This seems all well and good, but after the pack is discharged, you have to charge it up using electricity from the grid, which is burning fossil fuels most likely. (Knee-uke-ular would be a bit different). You are only displacing the pollution from what would have been a clean burn ICE to a remotely located dirty power plant.
I think using these high power/energy density batteries in conjunction with a very clean burn bio fuel ICE (hybrid) system would be much better for the environment. I can hear the wife now, "honey I forgot to charge the batteries and I'm stuck in the middle of I95.......
