More news on the M1 battery developed at MIT. Looks like the offshoot company that will be taking these to market will concentrate on the handheld tool market.



The M1, based on the same lithium-ion technology used in your cell phone and laptop, is the first product from MIT spinoff A123 Systems. Cofounder Yet-Ming Chiang, a materials science professor, succeeded in shrinking to nanoscale the particles that coat the battery's electrodes and store and discharge energy. The results are electrifying: Power density doubles, peak energy jumps fivefold (the cells pack more punch than a standard 110-volt wall outlet), and recharging time plummets. Going nano also solves a safety problem. Regular high-capacity Li-ion batteries tend to explode under severe stress, like if they're dropped from a ladder.

This is a SMART idea IMHO. It means that this company will be able to make a profit while positioning themselves to make a real splash with automakers. My only curiousity has to do with the recharge-time, and the energy spent. If you compare the total energy spent on recharging a conventional battery, to that of the M1 battery (which takes much less time) is there a significant net dropoff in the amount of total power needed? Or is it one of those things where the recharge process for conventional batteries was not very efficient? Perhaps some people who are really knowledgeable about this topic would be willing to chime in.
