▎ 摘　　要

NOVELTY - The utility model claims a sodium ion graphene comprising a bottom plate, two sides of the top part of the bottom plate are fixedly connected with a clamping mechanism, one side opposite to the two clamping mechanisms is movably connected with a box body, the inner cavity of the box body is movably connected with a battery pack main body, the top part of the box body is fixedly connected with a box cover through a bolt, two sides of the top part of the box cover are provided with a first through hole, the clamping mechanism comprises a limiting box, the bottom part of the limiting box is fixedly connected with the bottom plate, the back side of the top part of the limiting box is provided with a second through hole. The utility model is provided with a bottom plate, a clamping mechanism, a limiting box, a second through hole, a third through hole, a spring, a movable plate, a push rod, a pushing block, a locating block, a clamping block, a box body, a battery pack body, a current collector layer, graphene carbon fibre coating, a vanadium phosphate sodium active material layer, the matched use of the box cover and the first through hole, solves the problem that the existing sodium ion graphene pack is not convenient to disassemble. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the sodium ion graphene to claim.
