Envia Systems Awarded $4M ARPA-E Grant and $1M California Energy Commission Grant for Advanced Li-ion Storage for Vehicles
Envia Systems has been awarded a $4 million grant from the US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) and another $1 million from the California Energy Commission (CEC) to support development of high energy density Li-ion storage technology, targeted at plug-in hybrid and electric vehicles. (Earlier post.)
Envia, in partnership with Argonne National Laboratory, proposes to develop Li-ion batteries using nano silicon-carbon composite anodes and high capacity layered-layered manganese composite cathodes. Paired with the Si-C composite anode, a battery with more than 400 Wh/kg—about triple that of existing EV batteries—and long cycle life can be produced, according to the company.
In July 2009, the Envia/Argonne technology, which provides the highest energy and cycle life of all lithium-ion systems available today for the plug-in hybrid electric vehicle (PHEV) and electric vehicle markets, received an R&D 100 Award.
This product was jointly developed by a team from Argonne and Envia Systems. The Argonne team consisted of Michael Thackeray, Argonne Distinguished Fellow; Khalil Amine, senior scientist; Christopher Johnson, chemist; Sun-Ho Kang, materials scientist; Ilias Belharouak, materials scientist; and Haixa Deng, post doctoral appointee. Other researchers were Jaekook Kim, associate professor, now at Chonnam National University, Korea and Sujeet Kumar, co-founder and CTO of Envia Systems.
