Abstract

SEPARATOR MATERIALS FOR SECONDARY LITHIUM BATTERIES COMPRISING AS THE BASE MATERIAL A VINYLIDENE FLUORIDE- HAXAFLUOROPROPYLENE (VDF- HFP) COPOLYMER RESIN, WHEREIN POLYMER PARTICLES HAVING A HIGHER SOFTENING POINT THAT THE COPOLYMER ARE BLENDED AND DISPERSED IN THE SEPARATOR. AS THE POLYMER PARTICLES, FLUORINATED POLYMER PARTICLES ARE PREFERABLE. THE SEPARATOR MATERIALS FOR SECONDARY LITHIUM BAATTERIES ARE FREE FROM SHORT- CIRCUITING DURING THE STEP OF THE HEAT LAMINATION OF THE SEPARATOR ON ELECTRODE MEMBRANES.
