A comprehensive review of separator membranes in lithium-ion batteries

Lithium-ion batteries (LIBs) have been the leading power source in consumer electronics and are expected to dominate electric vehicles and grid storage due to their high energy and power densities, high operating voltage, and long cycle life [1].The deployment of LIBs, however, demands further enhancement in energy density, cycle life, safety, and

Recent progress of composite polyethylene separators for lithium

Commercial membrane separators used in LIBs typically have porosity values in the 40–60% range, which is required for efficient and fast ion transmission. High porosity contributes to better electrolyte uptake and lowers internal resistance, improving battery performance 38]. Mechanical properties typically decrease as separator porosity increases.
