▎ 摘　　要

NOVELTY - Lithium-replenishing functional electrolyte membrane comprises a framework layer, a reinforcing layer and a lithium electrolyte layer located between the two. The framework layer has a three-dimensional porous structure. The part of the lithium electrolyte layer is filled in the porous structure of the framework layer. USE - The lithium-replenishing functional electrolyte membrane is useful for solid-state lithium battery. ADVANTAGE - The lithium-replenishing functional electrolyte membrane replaces the traditional lithium-ion battery diaphragm, after assembling the battery, the first coil can be charged to supplement the lithium-ion, the cycle performance of the battery is improved; and the charge of the first ring will not damage the performance of battery. The lithium electrolyte layer is filled between the inner part of the framework layer and the reinforcing layer, can realize good lithium supplement, but also can avoid the lithium adding agent falling to the electrolyte. The lithium-replenishing efficiency is reduced. The inorganic solid electrolyte particles not only can increase lithium-ion conduction, can enhance the heat resistance of the membrane, reduce the thermal contraction and thermal puncture of membrane; and can also reduce the loss of lithium-ion in the anode active material to adjust the amount of the lithium according to the anode and cathode system. The inorganic solid electrolyte particles in the lithium-replenishing electrolyte layer not only can increase the lithium-ion conduction, can enhance the heat resistance of the membrane and reduce the thermal contraction and thermal puncture of the membrane.
