摘要：
Nano SiO2 were doped in PI film and then treated with HE solution to get PI microporous membranes. The PI separator was characterized by SEM, thermal shrinkage, AC impendance and charge-discharge experiments. The results show that the thermal performance of PI separator is superior to PP separator and the safety of Lithium-ion battery can be greatly improved.
