This application provides a battery packaging material. The battery packaging material has both a high-temperature-resistant fireproof characteristic and a fire-retardant fireproof characteristic, and therefore has a powerful fireproof function. The battery packaging material is successively disposed with a protective layer, a metal layer, and an encapsulating layer from outside to inside, where a first high-temperature-resistant layer is disposed between the metal layer and the protective layer; a second high-temperature-resistant layer is disposed between the metal layer and the encapsulating layer; and a fire-retardant layer is disposed above the protective layer, between the protective layer and the metal layer, between the metal layer and the encapsulating layer, or below the encapsulating layer.
