▎ 摘　　要

NOVELTY - The battery has a header (11), an air solid angle (22), a graphene battery (33), and an embossed plate (44). The header runs through the inside of the graphene battery. The air solid angle is installed on the outer surface of the graphene battery. The embossed plate is welded to the outer surface of the graphene battery. The outward movement strip is attached to the outer surface of the abutment plate, and an end of the abutment plate is away from the outward movement strip and the outer bracket. USE - Graphene battery with easy replacement of high volume energy for electric bicycle. ADVANTAGE - The graphene battery is supported in the middle without friction with the inner case. The internal resistance is eliminated, and allowing stretching back to the top pole, and thus allowing to fill the gap, which is used in graphene batteries. The internal resistance of the restricted space, the corners are retracted and installed smoothly. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a high-volume, easily-replaceable graphene battery of an electric bicycle.
