Document Type and Number:
Japanese Patent JP2011210524
Kind Code:
A
Abstract:
To provide a stack type battery capable of surely fixing a separator by thermal welding without occurrence of contraction or short circuit, capable of performing a shutdown function at abnormal heat generation in order to secure safety.
In the stack type battery with a plurality of positive electrode plates 1 and negative electrode plates 2 alternately laminated through a separator 3, the separator 3 is to have a structure with heat-melting layers 3M each having a shutdown function and a melting point lower than that of a heat-resistant layer 3R arranged over the entire surface of both sides of the heat-resistant layer 3R with heat resistance. The heat-melting layers 3M of the separator 3 are fixed to each other by thermal welding.
