▎ 摘　　要

NOVELTY - Thermal battery intermediate layer comprises carbon materials, ceramic powders, or a mixed material with a solid electrolyte. The thermal battery intermediate layer is placed between the anode, the separator, and the cathode in any relative position, including (a) anode-intermediate layer-diaphragm, (b) cathode-intermediate layer-diaphragm, (c) anode -diaphragm-intermediate layer, (d) cathode electrode-diaphragm-intermediate layer, (e) diaphragm-intermediate layer-diaphragm. The diaphragm-intermediate layer-diaphragm can be repeatedly installed in the same single thermal battery for many times. The middle layer of the heat battery is within the working temperature range of the heat battery of 200-800°C, and the composition of the middle layer material itself does not change. USE - Thermal battery intermediate layer is used in military weapon systems, e.g. hypersonic cruise missiles. ADVANTAGE - The thermal battery intermediate layer does not block the transmission of the lithium-ion molten salt at high temperature while blocking the shuttle effect. It is simple to assemble and also breaks the assembling mode of the existing heat battery. It improves the specific capacity of the current all heat battery anode to greatly increase the heat battery than the energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of thermal battery intermediate layer.
