SECONDARY BATTERY, ELECTRODE THEREFOR, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an electrode for secondary batteries that can bring out a high-output effect to the maximum by using an electrode active material having a small particle, and has small internal resistance in the electrode for secondary batteries using the electrode active material having a small particle diameter; to provide a manufacturing method of the electrode; and to provide a high-output nonaqueous secondary battery using such an electrode for secondary batteries.

SOLUTION: The electrode for secondary batteries uses the electrode active substance comprising a small particle having an average particle diameter of 10 μm or smaller. A particle diameter ratio RD(DE/DA) of a particle diameter DEin a conductivity additive agent contained in the electrode to an average particle diameter DAin the electrode active material is set to less than 5 or preferably equal to or less than 1.
