In this poster, a optimized dispersity propery of ceramic-coating separator for lithium-ion batteries is successfully prepared by forming a ceramic layer consisted of Al2O3 powder and mix binder onto one side of pristine PE separator.
During the preparation of the separator, water is used as solvent and a very small amount of a mixture binder is applied as binder to obtain better thermal stability. The effect of dispersity property of the ceramic-coating layer on its thermal stability, physical properties and electrochemical performance is also investigated. The results clearly showed that the ceramic-coating separator with SBR–CMC binder has wonderful thermal stability, good wettability and high uptake of liquid electrolyte.
