Venturebeat recently headlined news that Envia, a battery development company in Newark, California had developed and was testing a lithium ion battery with a capacity of 400 watt-hours/kilogram. This is far in excess of the current record for such batteries, which is a little more than half of the Envia number. Assuming manufacturing cost in the same range as currently the Envia battery suggests that reductions from around $300 per kilowatt hour to $125 per kilowatt hour will be possible in the foreseeable future. Put another way, we might be looking at a cost reduction of $25K for the Tesla S and $15K for the Chevy Volt with no change in performance. Affordable electric cars? Electric cars that will be bought by regular folks rather than the eco-conscious? Only time will tell and whether Envia has really done what it claims to have done. The Envia web site has an interesting write up on the company and this development – enviasystems.com.
