▎ 摘　　要

NOVELTY - A negative electrode material, comprises 0.0800.5% a graphene powder with a particle size of 10-20 μm, a specific surface area of 160-200 m2/g, an average thickness of less than 4 nm, and a purity of greater than 99%. USE - Negative electrode material useful for a lead-acid storage battery. ADVANTAGE - The lead acid storage battery negative electrode is added with nano graphene powder in the paste formulation, so that the active material particles, the active substance and the plate grid conductive ability is stronger, and the structure is more stable, thus reducing the temperature rise generated when charging and discharging, also reducing the corrosion speed of the grid, and improving the charging receiving capacity of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the negative electrode materials for acid storage batteries, which comprises stirring and mixing raw materials in sequence.
