Lithium ion battery are one of representative rechargeable batteries with high energy density, tiny memory effect, and low self-discharge and composed of anode, cathode, electrolyte, and membrane separator. The importance of membrane separator has been improved further as electric vehicle market increases rapidly. The conventional membrane separators are based on polyolefin (e.g., polyethylene and/or polypropylene). In case of lithium ion battery with a high capacity, polyolefin membrane separators are suffering from low thermal resistance and easy short-circuit formation leading to overheating. For these reasons, in this study, gel polymers are in-situ synthesized in electrolytes used as solvent, which are located in pores of polyolefin separators to obtain gel polymer electrolyte-polyolefin reinforced membranes.
