COATING COMPOSITE FOR ACTIVE MATERIAL LAYER, ELECTRODE PLATE FOR NON-AQUEOUS ELECTROLYTIC LIQUID SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTIC LIQUID SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a coating composite for active material layer by which an electrode plate for non-aqueous electrolytic liquid secondary battery having a good storage stability and high battery capacity can be manufactured, an electrode plate for non-aqueous electrolytic liquid secondary battery realizing high battery capacity and having hardly a problem such as deterioration of cycle characteristics and increase of internal resistance, and further a non-aqueous electrolytic liquid secondary battery assembled with the electrode plate having a high battery capacity with good cycle characteristics and low internal resistance.

SOLUTION: This is a coating composite for active material layer which contains a conductive material 2 pts.wt. or less against active material 100 pts.wt, and contains carbon black having oil absorption amount of dibutyl phthalate of 250 ml/100 g or more and BET specific surface area of 50-150 m2/g, 50 wt% or more in the whole conductive material. Further, this is an electrode plate for non-aqueous electrolytic liquid secondary battery which is provided on one side or both sides of a current collector with an active material layer that contains a conductive material 2 pts.wt. or less against active material 100 pts.wt. and contains carbon black having oil absorption amount of dibutyl phthalate of 250 ml/100 g or more and BET specific surface area of 50-150 m2/g 50 wt% or more in the whole conductive material.
