UV OR EB CURED POLYMER-BONDED CERAMIC PARTICLE LITHIUM SECONDARY BATTERY SEPARATORS, METHOD FOR THE PRODUCTION THEREOF

摘要

Porous, electrically insulating, and electrochemically resistant surface coatings that strengthen and protect separators and that improve the operational safety of electrochemical devices using such separators, porous, electrically insulating, and electrochemically resistant standalone separators, the use of ultraviolet (UV) or electron beam (EB) curable binders to secure an electrically insulating, porous, ceramic particle coating on separators or to produce standalone separators, and methods of producing polymer-bound ceramic particle separator coatings, separators and electrochemical devices by UV or EB curing slurries of reactive liquid resins and ceramic particles.
