Under the auspices of the ARPA-E grant, Envia has been able to demonstrate very high capacity (1530 mAh/g) and promising cycle life performance using silicon-carbon nanocomposite anodes. We successfully achieved the ARPA-E program goal to produce a battery with an energy density of 400 Wh/kg. We are currently scaling up the material using a low cost production process. This anode will be ready for commercialization in 2012 and will complement Envia’s high capacity cathode very well.
