Patent ID: 8202652

Claim:
A slurry composition for a positive electrode for a lithium ion secondary battery, comprising: a polymer A wherein a HOMO (Highest Occupied Molecular Orbital Energy) value by a semiempirical method molecular orbital calculation is −13.5 eV to −10 eV, a glass transition temperature is −80° C. to 0° C. and a content of ethylene repeating units is 35 mol % to 90 mol %; a polymer B wherein a HOMO value by a semiempirical method molecular orbital calculation is −13.5 eV to −10 eV, a glass transition temperature is −80° C. to 0° C., and a gel content is 50 wt % or more; an active material for a positive electrode; a conductivity adding agent; and a liquid medium C in which the polymer A dissolves but the polymer B does not dissolve.
