Graphene heating layer based storage battery heating insulation sheath and preparation method thereof

The invention relates to a graphene heating layer based storage battery heating insulation sheath and a preparation method thereof. The storage battery heating insulation sheath is used in the fieldsof electric vehicles, solar power generation, wind power generation, electric power valley energy storage, military storage batteries such as an uninterruptible power supply and the like, and energy storage. According to the graphene storage battery heating insulation sheath, an upper cover surface layer, a right side surface layer, a front side surface layer, a left side surface layer, a back side surface layer and a bottom surface layer are mutually connected to form a hexahedron; a storage battery is wrapped in the hexahedron of the graphene heating layer storage battery heating insulationsheath; the problems that the storage battery is low in output efficiency and low in power in a low-temperature state and the charging and discharging capacity is severely reduced or even cannot be used are solved by utilizing
