Title:
COMPOSITION FOR HEAT RESISTANT POROUS LAYER FORMATION, SEPARATION FILM INCLUDING HEAT RESISTANT POROUS LAYER, ELECTROCHEMICAL BATTERY ARRANGED BY USE OF SEPARATION FILM, AND METHOD FOR MANUFACTURING SEPARATION FILM
Document Type and Number:
Japanese Patent JP2016127028
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: a separation film which can retain its own form rather than bursts even under an environment such that the temperature in a battery is raised to 200°C or higher in several seconds, and which has a good adhesive force; and an electrochemical battery arranged by use of such a separation film.SOLUTION: An electrochemical battery separation film and an electrochemical battery are provided. The separation film comprises: a porous base material; and a heat resistant porous layer formed on one or each face of the porous base material. In the separation film, the heat resistant porous layer includes a crosslink type binder. The separation film has a tensile strength of 50-350 kgf/cmafter left at 200°C for 10 minutes.SELECTED DRAWING: Figure 1
