▎ 摘　　要

NOVELTY - The lithium metal battery has a positive electrode, a negative electrode, and a separator. The separator has a first layer of an isolation film comprising an electronically insulating material, a second layer of a separator comprising at least one of an electronically conductive material or a substance that is reactive with lithium metal, and a third layer of barrier film comprising an electronically insulating material. The electronic conductivity of the second layer of the isolation film is 102-108 S/cm. USE - Lithium metal battery for use in an electronic device (claimed) such as a notebook computer, a pen-input computer, a mobile computer, an electronic book player, a portable telephone, a portable facsimile, a portable copier, a portable printer, a headphone, a video recorder, a liquid crystal TV, a handy cleaner, a portable compact discplayer, a mini disc, a transceiver, an electronic notebook, a calculator, a memory card, a portable recorder, a radio, a backup power source, a motor, an automobile, a motorcycle, a power-assisted bicycle, a lighting fixture, a toy, a game machine, a clock, an electric tool, a flashlight, a camera, a large-sized household battery and a lithium ion capacitor, and an energy storage power station, a marine vehicle, and an air vehicle. ADVANTAGE - The isolation film with the multilayer structure can inhibit the growth of lithium dendrites in the circulation process of the lithium metal battery, avoid the lithium dendrites to pierce the isolation film, and obviously improve the circulation performance and the safety performance of the lithium metal battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structure of the isolation film.
