“…At microscale, the temperature and stress gradients are coupled [32]. Temperature rise causes microstructure expansion and generates stress gradient [33], leading to deformation, stress migration and interface segregation [34]. High energy, which is needed for long-distance cruising, and high power, which is required for heavy load, will result in instantaneous large current and rapid temperature rise in non-equilibrium state [35,36].…”

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. Energy shortages and air pollution are the primary challenges facing global automotive industry. The transport sector accounts for 52% in global oil consumption in 2010 [1]. The world retains about 800 million cars and the number will reach 1.2 billion by 2020. Transport sector's energy consumption has become the main source of pollution and greenhouse gas emissions, making energy transformation imperative. New energy is the clean energy to replace gas and diesel, with high efficiency, environment friendliness, and low emissions. Nickel-hydride, lithium battery, and fuel cell are the major clean energies to provide power and become highly efficient for new energy vehicles, including hybrid electric vehicle, battery only electric vehicle and fuel cell vehicle. Energy battery is green energy and independent from the bottleneck of oil productivity, attracting attentions from many governments, research institutions and enterprises for R&D [2,3]. Among new battery materials, membrane materials work in a complex environment with high requirements for performance and are the first to degrade (even if other anode and cathode materials still work), becoming a weakness for battery system [4,5]. Membrane material properties determine the battery's thermal effects and resistance, directly affecting the battery performance and service life. Therefore, it is urgently needed to enhance the service performance and extend battery life. Taking proton exchange membrane materials, lithium battery separator materials, and nickel-hydride battery separator materials as examples, the paper introduces the research progress of membrane materials and discusses new methods to improve the performance and service life.
