Hence, lithium ion transport across the PE separator treated by benzoyl peroxide is effectively facilitated by the formation of oxygen functional groups, leading to improved ionic conductivity. The LiB cells assembled with the PE separator treated by BPO exhibit remarkable rate capability and outstanding capacity retention (98.1%) after 70 cycles.
