▎ 摘　　要

NOVELTY - The battery has a locking block (32) whose outer edge of the bottom end is provided with an inclined surface. A spring (34) is connected between the top of the locking block and the inner end of the sliding groove. The outer port of a baffle (3) at the other end of a protective housing (2) is provided with a matching ring (4). The outer diameter of the matching ring is the same as the inner diameter of the annular baffle on the side of the locking block. The outer wall of the matching ring corresponding to the locking block is symmetrically provided with locking grooves matched. The two electrode blocks (11) adjacent to the two battery cores are in contact with each other when the locking block on the battery core is matched with the locking groove on the connected other battery core. USE - Graphene battery. ADVANTAGE - The locking block and the locking groove that are engaged with each other connects the two batteries stably and effectively, and greatly improves the stability and convenience of the graphene battery in use. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene battery. Protective housing (2) Baffle (3) Matching ring (4) Electrode block (11) Locking block (32) Spring (34)
