The development of high power Li-ion batteries is of great relevance for hybrid electric vehicles (HEVs) technology. Electrochemical performance of high voltage cells operating with new fluorinated separators and ethylene carbonate - dimethyl carbonate 1M LiPF6 electrolyte with additives was evaluated according to the FreedomCAR DOE protocols to simulate the dynamic functioning of batteries in plug-in HEVs. The results compared to those of cells with commercial separators evidence the beneficial impact of the new fluorinated separators.
