Inventors include Yuasa Ryuuto; Ishiwatari Nobuyuki; and Yokomizo Masakazu.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present invention relates to a carbon material composition in which the proportion of particles having a volume-based particle size distribution of 3 µm or less is 16.0-40.0%, and the maximum torque in measurement of the oil absorption amount for linseed oil is 13.0 N·m or less. The present invention also relates to a carbon material composition in which the proportion of particles having a volume-based particle size distribution of 3 µm or less is 16.0-40.0%, wherein the ratio (SAe/SAp) of the specific surface area SAe when the carbon material composition is formed into an electrode plate to the specific surface area SAp of the carbon material composition in powdered form is 0.70-1.00 (the specific surface area SAe is the specific surface area of the electrode plate in which the carbon material composition is used).
