NOVELTY - The battery has a conductive rod (1-1) welded with a conductive sheet (1-2). An end of a negative pole piece (1-3) is connected with the conducting sheet and tightly wound on the conductive rod. A gel electrolyte positive air electrode (2) comprises a gel electrolyte layer. A positive electrode current collector (3) is connected with a positive electrode lead joint (4). An air separating film (7) is covered on a cathode gas sealing head (5). The conductive rod is connected with the cathode gas sealing head by a screw thread.    USE - Changing electrode winding type lithium-air solid-state battery.    ADVANTAGE - The battery connects a conductive electrode sheet and a negative electrode sheet with a tension cable winch in an automatic manner, so that positive and negative electrodes are completely utilized, thus improving working efficiency.    DETAILED DESCRIPTION - The conductive rod is made of stainless steel, copper alloy, aluminum alloy, magnesium alloy, nickel alloy, titanium alloy, oxyacetylene, polyphenol, doped conductive polyester plate, doped conductive amino nitrile and doped conductive aramid fiber or conductive polyimide.
