The invention provides a battery roll core packaging device. The battery roll core packaging device comprises an upper positioning plate and a lower positioning plate which are hinged together, wherein grooves are formed in the upper positioning plate and the lower positioning plate, when the upper positioning plate and the lower positioning plate are in a closed state, the grooves in the upper positioning plate and the lower positioning plate form a battery cavity for accommodating the battery roll core. The battery roll core packaging device is simple in structure and convenient to operate, when the battery roll core is packaged, the stamping process is omitted, therefore, raw materials are saved, damage to an aluminum-plastic packaging film is avoided, and the safety performance is improved.
