NOVELTY - The utility model claims a photovoltaic power generation direct current energy storage battery, comprising a storage box, the bottom of the storage box is equipped with a storage seat, the mounting plate is installed on one side of the inner wall of the storage box, one side of the mounting plate is equipped with a drying box, the inner part of the drying box is equipped with a barrier net, one side of the barrier net is filled with graphene main body, one side of the inner wall of the drying box is fixed with a circulating hole. The utility model through the mounting plate is installed on one side of the inner wall of the storage box under the help of the screw, and then the drying box and the mounting plate are fixed, because the barrier net is placed in the drying box, the graphene body can be filled in one side of the barrier net, the barrier net for separating the main body graphene Because of the filling graphene the main body, it can be moisture under the opening of the flow hole, the position of the graphene body is adsorbed, to a certain degree of moisture-proof ability, improves the protection process of the direct current energy storage battery main body.
