Title:
CONDUCTIVE POROUS LAYER FOR BATTERY, AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/168810
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a conductive porous layer for a battery in which the adhesion between a conductive porous substrate and the conductive porous layer is excellent, and in which the pores in the conductive porous layer are not crushed.
This conductive porous layer for a battery comprises a layered body having a first conductive layer and a second conductive layer. The first conductive layer and the second conductive layer each contain a conductive carbon material and a high molecular weight polymer, and the Tg of the high molecular weight polymer contained in the first conductive layer is at least 30°C higher than the Tg of the high molecular weight polymer contained in the second conductive layer.
