Title:
化学電池用のセパレータ紙
Document Type and Number:
Japanese Patent JP6449888
Kind Code:
B2
Abstract:
A paper suitable for use as separator in an electrochemical cell, including at least 60 wt. % of an aramid fibril and at least 1 wt. % of an aramid fiber. The paper has a grammage of 5 to 100 g/m2, and the aramid fibril has a Canadian Standard Freeness (CSF) in a wet phase of less than 300 ml and a specific surface area (SSA) after drying of less than 3 m2/g. It has been found that a paper with this composition combines good electrolyte absorption and ion permeability with high stability during use, leading to a long lifetime for the electrochemical cell.
