Abstract: With the application of spinel LiMn2O4 cathode material and new seperator, a 60 Ah LiMn2O4-based lithium ion battery for plug-in hybrid electric vehicles (PHEV) was developed on the basis of studying the influence of electrode fabrication technology and electrolyte on the rate charge-discharge and cycling performance. Battery electrochemical performances were studied, including rate charge-discharge, cycling and storage. Lithium ion battery module (88 cells in series) for PHEV was also prepared. The rate discharge, 10 s. pulse power, 30 s. pulse power and fast charge performances for the module have been evaluated. The results indicated that the 60 Ah LiMn2O4 lithium ion battery has excellent performance on rate discharge, fast charge, cycle life and storage, it is a promising battery of PHEV applications.
