A PI/cellulose composite separator was prepared by adsorbing bacterial cellulose on a PI separator prepared via a papermaking process. The PI/cellulose separator exhibited good thermal stability and electrolyte wetting properties compared to commercial celgard 2340 separator. The amount of bacterial cellulose added was 20%. Bacterial cellulose fills the porosity of the PI separator. The PI/cellulose composite separator possesses excellent thermal stability even at 200 °C and high electrolyte wettability with a contact angle of 58°.
