Title:
COMPOSITION FOR POWER STORAGE DEVICE, SLURRY FOR POWER STORAGE DEVICE ELECTRODE, POWER STORAGE DEVICE ELECTRODE, AND POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2023049608
Kind Code:
A
Abstract:
To provide a composition for a power storage device, which suppresses occurrence of electrode corrosion and decomposition of thickeners by preventing temporal pH increase in slurry for a power storage device electrode, and can improve adhesion and charge/discharge endurance characteristics of a power storage device electrode.SOLUTION: A composition for a power storage device according to the present invention contains a polymer particle (A) and a liquid medium (B). When the total of repeating units that are included in the polymer particle (A) is 100 mass%, the polymer particle (A) contains 5-50 mass% of repeating units (a1) derived from an unsaturated carboxylic acid ester with a hydroxyl group, and 50-90 mass% of repeating units (a2) derived from an unsaturated carboxylic acid ester (excluding the unsaturated carboxylic acid ester with a hydroxyl group). At least a part of a hydroxyl group contained in the unsaturated carboxylic acid ester with a hydroxyl group is protected with a protecting group.SELECTED DRAWING: None
