BINDER COMPOSITION FOR LITHIUM ION SECONDARY BATTERY ELECTRODES, LITHIUM ION SECONDARY BATTERY ELECTRODE, AND LITHIUM ION SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a binder composition for lithium ion secondary battery electrodes capable of obtaining a lithium ion secondary battery which can stably provide a high charge/discharge capacity. ! SOLUTION: A binder composition for lithium ion secondary battery electrodes comprises an emulsion including polymer particles originating from an ethylenic unsaturated monomer distributed in a polyvinyl alcohol-based resin solution. The polymer particles have an average particle diameter of 50 nm or more and less than 600 nm. ! COPYRIGHT: (C)2015,JPO&INPIT
