Abstract:

Research progress of lithium-ion battery separator modified with inorganic ultrafine powder in recent years was reviewed.First,the modification methods and effects of commercial Al2O3 and AlOOH on traditional polyolefin separators and new electrospun separators were introduced,which had been used in the modification of lithium battery separators.Then,the modification of lithium-ion battery separator by conventional inorganic materials TiO2 and SiO2 powder was described.Finally,BN and other unconventional inorganic materials modified separator was introduced briefly.The effect of the composition,structure and performance of the inorganic materials modified separator on the overall performance of lithium-ion batteries were summarized and discussed,and its future development trend of the inorganic material modified lithium battery separator was prospected.

Key words: ultrafine powder, lithium-ion battery separator, alumina, boehmite
