Abstract

Provided is a composite electrolyte membrane comprising a porous support including a polymer having a melting point of at least 145°C and a coating layer on at least one side of the support, wherein the coating layer includes a polymer binder and hydrophilic oxide particles. The membrane exhibits high heat resistance and improved ionic conductivity, and is suitable for use in electrochemical devices, such as lithium secondary batteries. Experimental results demonstrate excellent capacity retention, stability, and performance compared to conventional polyolefin-based separators, making the membrane advantageous for high-capacity and high-safety battery applications.
