Advance in ceramic-based composite separator for lithium-ion battery

Compared with the conventional polyolefin separator,organic-inorganic composite separator has enough flexibility and temperature resistance as well as electrolyte affinity. In this paper ceramic composite separators for lithium-ion battery are reviewed,including advantages of this type separator compared with traditional separators,structural styles and composition materials of ceramic-based composite separator,and worldwide research and development status of ceramic composite separator. Finally the development trend of composite separator is predicted. With the development of lithium ion battery,high performance ceramic composite separator will replace traditional polyolefin separator and become the main separator to meet the needs of batteries.
