Progress in research on the performance and service life of batteries membrane of new energy automotive

Abstract

Batteries membrane materials are widely used in new energy automotives such as hybrid vehicles, fuel cell vehicles, and pure electric vehicles. Membrane consists of two categories: fuel cell membrane (power unit) and power battery membrane (charge and discharge device). With rapid development of the processes and technology of cell membrane materials, there is urgent need to study their properties and service life. The article summarizes the recent research progress in proton exchange membrane materials, lithium battery separator materials, and nickel-hydrogen battery separator materials. Based on our laboratory research, the paper features the affecting factors and mitigation strategy of performance and service life for automotive battery membrane materials. Future direction for the batteries membrane material of new energy automotive is discussed. © 2012 The Author(s).
