The United States Advanced Battery Consortium (USABC), an organization whose members are Chrysler LLC, Ford Motor Company and General Motors Corporation, has awarded a $6.5 million lithium-ion battery technology development contract to Ener1’s EnerDel subsidiary.
USABC awarded the contract in collaboration with the US Department of Energy (DOE) to develop lithium battery technology for hybrid-electric vehicle applications. The 18-month contract, valued at $6.5 million, is the second of a three-phase USABC program and requires a 50% cost share. EnerDel successfully completed Phase I in June. (Earlier post.)
Under the full, three-phase program, EnerDel is working to develop a fully integrated battery system for use in hybrid vehicle applications. The USABC program aims to produce a cost-competitive, lithium-ion battery that is lighter, smaller and higher in power than existing battery technologies for hybrid electric vehicles.
EnerDel’s Phase II contract involves development focused on scaling up to a production caliber cell, lifetime testing and evaluation, and demonstrating the technology in battery modules.
EnerDel has developed its own lithium titanate (titanium oxide, “LTO”) anode material in collaboration with Argonne National Laboratory (ANL) for HEV applications. The company has also developed a hard carbon (HC) anode lithium-ion high capacity battery that it will target at plug-in hybrid (PHEV) and battery electric vehicle (BEV) applications. For the cathode, EnerDel uses manganese spinel (LiMn2O4, “LMO”). EnerDel uses a flat prismatic cell design.
The 5Ah LTO-type cell carries a nominal voltage of 2.5V; the 5Ah HC-type cell carries a nominal voltage of 3.6V.
