Envia Systems claims energy density record for lithium-ion batteries

Submitted by GregW on Tue, 06/03/2012 - 11:57

- Two to 3 times times current energy density

- testing by ARPA-E

- $7 million from GM

Ticks all the boxes for a serious effort with good prospects for real world production.

Hopefully, all the above & the, "should cost less than half the price of existing li-ion batteries", makes it into production soon.
