SLURRY COMPOSITION FOR SECONDARY CELL POSITIVE ELECTRODE, SECONDARY CELL POSITIVE ELECTRODE AND SECONDARY CELL

摘要

A slurry composition for secondary cell positive electrode which comprises a polymer (A) having a HOMO value by semi-emprical molecular orbital calculation of 13.5 eV to 10 eV and a content of an ethylenic recurring unit of 30 mol % to 95 mol %, a polymer (B) having a HOMO value by semi-emprical molecular orbital calculation of 13.5 eV to 10 eV, a glass transition temperature of -80 DEG C to 0 DEG C and a gel content of 50 wt %, a positive electrode active material, an electroconductivity imparting agent, and a liquid medium (C) being capable of dissolving the polymer (A) and not capable of dissolving the polymer (B). The slurry composition can be used for manufacturing a lithium ion secondary cell which has a high cell capacity and an excellent charge-discharge cycle characteristics and is improved in charging rate characteristics.
