Solid-state, rechargeable Li/LiFePO4 polymer battery for electric vehicle application

A solid-state polymer lithium metal battery having a wLiFePO(4)/C composite cathode and a poly(ethylene oxide) PEO-based solid polymer electrolyte was assembled and characterized in terms of specific energy and power according to the protocol for electric vehicle (EV)application set by the USABC-DOE. The results of these tests show that this polymer battery surpasses the goals stated by USABC-DOE and, hence, may be suitable for application in the evolving EV market. (C) 2010 Elsevier Mi.
