Separator plays a major role in lithium-ion batteries. For conventional polyolefin separators, low porosity is a serious problem, which will affect the electrochemical performance of lithium-ion batteries. In this work, we prepared membranes with different porosities by controlling the amount of oxidant in the Tempo oxidation process. 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidation bacterial cellulose (TOBC8) separator exhibits suitable porosity (65%), excellent wettability, high lithium ion conductivity (0.388 mS cm−1), and outstanding cycle stability.
