NOVELTY - The utility model claims a new energy-saving graphene anti-collision rechargeable battery unit, comprising a sealing cover and graphene charging rod, a sealing cover sealing the upper end middle part connected with the first telescopic through round hole of the movable contact rod is installed in the middle of the upper end of the first telescopic cylinder, sealing by the inner thread screw matched with the outer screw thread port of the battery cylinder on the outside of the corresponding second spring end is fixed connected with the second telescopic cylinder bottom, the second bottom end of the telescopic cylinder is fixedly connected to the lower part of the inner side of the square cylinder. The graphene rechargeable battery unit, clockwise rotating cover, namely the cover cylinder part is removed from the battery, can change the graphene rechargeable battery electrolyte, a first spring contact piece, the contact piece charging rod less than graphene, and graphene charging rod inside the first telescopic cylinder, reduces the air consumption of the graphene rechargeable battery electric quantity, from square tube through the second spring can absorb the impact force, which greatly reduces the damage of the battery cylinder.
