NOVELTY - The utility model claims a protective cover of nickel-hydrogen battery with high-efficiency radiating, comprising a first protective cover body, the inner wall of the first protective cover body is provided with a graphene radiating layer; the inner wall of the graphene radiating layer and located at the left side is provided with an insulating circular plate; the left side of the insulating circular plate is provided with an insulating radiating port; the side wall of the first protective cover body and located at the upper side is provided with a first opening; the side wall of the graphene radiating layer and located at the upper side is provided with a first elastic sheet; the upper surface of the first elastic sheet fixedly connected with a first toggle rod; the side wall of the first protective cover body and located at the lower side is provided with a second opening. In the utility model, through the aluminium protective cover body and graphene radiating layer for radiating the nickel-hydrogen battery, graphene has good thermal conductivity, can effectively conduct the heat to the protective cover body to emit out; the elastic sheet structure and the annular cover can effectively fix the nickel-hydrogen battery in the protective cover.
