China’s New Nanofibrous Power Lithium-Ion Battery Separator and its Commercialization Status

Abstract

The development of separator is the key issue in the development of lithium battery and further more in hybrid power automobile and BEV Nowadays, the lithium-ion battery separator industry in China falls short of independent innovations and global competitiveness, and is still at its early stages. In addition, the demand of separators in China still relies on import. The nanofibrous lithium-ion battery separators produced by electrospinning bears the quality of high cycle performance, strong thermal stability, and high discharge rate etc, thus can meet the needs of high-standard batteries. In this study, we introduce the new electrospun fibrous separators, present its manufacturing procedures and products properties, analyze the status of the lithium-ion battery separator industry and put forward possible solutions.
