▎ 摘　　要

NOVELTY - Producing a battery part comprises: forming graphene nanoparticles using carbon inclusive gas; combining the graphene nanoparticles with at least one dispersing agents to form a combination; and mixing the combination with a battery part liquid. USE - The method is useful for producing a battery part (claimed) e.g. aluminum-ion batteries. ADVANTAGE - The method provides the battery including the battery part that has an energy density of greater than 50-500 Wh/kg and/or a volumetric energy density of 20-1000 Wh/l, and increased voltage up to 3.4-3.8 volts. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a battery including multiple cathodes, separators and anodes in an assembled battery cell to linearly increase the voltage and also increase the cell capacity.
