COMPOSITE FOR BATTERY CASE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A composite material for a battery case is provided to prevent the degradation of mechanical properties and to improve heat conductivity of existing heat-radiant materials by inserting a knit which is not filled with a filler through laminating. CONSTITUTION: A composite material for a battery case comprises a structure a polymer based heat-radiant layer(10) and a knit layer(11) are alternately arranged and integrated, and radiates heat generated from a heat source through the heat-radiant layer. The heat-radiant layer filled with a heat-radiant filer(12). The knit layer is not filled with the heat-radiant filler. The heat-radiant filler is arranged in a thickness direction and transfers heat in a through-plane direction. The heat-radiant filler and knit layer can be applied to the battery case which is for fixing a pouch type battery or a housing for coupling the battery case.
