Lithium-Ion Battery Technology Complements Previous Breakthroughs
|Positive Impact:||With support from EERE, Envia has achieved a breakthrough that would enable three times the battery energy density of current lithium-ion batteries and reduce their cost by more than half.|
|EERE Investment:||$5 million|
|Clean Energy Sector:||Sustainable transportation|
Building on advanced battery innovations enabled by EERE, Envia Systems of Newark has become a world leader in the race to commercialize high energy lithium-ion batteries that could result in better performing, less expensive plug-in electric vehicles. Envia's innovative battery cells use a breakthrough mixed-metal cathode material invented at DOE's Argonne National Laboratory and developed through a decade of sustained EERE support. General Motors has found Envia's battery technology using the cathode so promising that it has invested $7 million in the company. With the help of a 2009 ARPA-e award, the Newark startup is also developing and incorporating a silicon-based anode designed to further boost driving range, lower production costs, and improve safety. Through the U.S. Advanced Battery Consortium—a cooperative agreement between DOE and automakers—and an individual cost-share partnership with EERE, Envia continues to optimize this cathode technology. In February 2012, Envia announced it had achieved a breakthrough that would enable three times the battery energy density of current lithium-ion batteries and reduce their cost by more than half.
The Vehicle Technologies Office (VTO) develops and deploys efficient and environmentally friendly highway transportation technologies that will enable America to use less petroleum. These technologies will provide Americans with greater freedom of mobility and energy security, while lowering costs and reducing impacts on the environment.
