This battery combines the excellent electrical conductivity of graphene and the high energy density of lithium-ion batteries, thereby improving the charging and discharging speed, energy density, and cycle life of the battery.

[0003] The existing graphene lithium battery core battery is composed of a positive electrode, a negative electrode, an electrolyte, and a battery package. When the graphene lithium battery core battery is transported, the battery is placed in a transport box. Since the road may be rough during transportation, the transport vehicle may jolt, causing the battery to shake and rub against the inner wall of the transport box during transportation, resulting in wear on the battery surface and thus affecting the transportation quality. Therefore, in view of the above problems, we have proposed a graphene lithium battery core battery. Summary of the Utility Model
