SLURRY FOR STORAGE DEVICE ELECTRODE, STORAGE DEVICE ELECTRODE, AND STORAGE DEVICE

摘要

This slurry for storage device electrodes comprises (A) polymer particles, (C) particles of a lithium-containing nickel composite oxide, and (D) water, wherein the polymer constituting the polymer particles (A) has repeating units derived from an unsaturated carboxylic acid and the slurry for electrodes has a total content of sodium and potassium less than 0.02 mass% of the slurry. The lithium-containing nickel composite oxide is inhibited from altering, thereby making it possible to produce a storage device which has a high battery capacity and excellent charge/discharge rate characteristics.
