▎ 摘  要

NOVELTY - The pack has a battery core (2) that is accommodated in a cavity. The battery core is in contact with one of strips (11) to deform a deformed portion (111) of the strip. The battery core includes a positive electrode (21), a negative electrode (22) and a separator (23). The separator is located between the positive electrode and the negative electrode. Graphene material is provided on the negative electrode. A positive ear (211) is connected to the positive electrode. The positive ear is connected to a positive terminal (12). A negative ear (221) is connected to the negative electrode, and the negative ear is connected to a negative terminal (13). An explosion-proof structure (3) is provided on a casing (1). An explosion-proof structure includes a groove (31) opened on the top surface or side surface of the casing. USE - Self-alarm explosion-proof graphene battery pack. ADVANTAGE - The application has the effects of high safety performance, fast charging and high bearing capacity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the self-alarm explosion-proof graphene battery pack.
