▎ 摘　　要

NOVELTY - Preparing all-solid-state electrolyte battery, comprises (i) preparing the anode sheet, cathode sheet and separator of the electrode, (ii) assembling the anode sheet, the cathode sheet and the separator to obtain a bare cell, (iii) placing the bare cell into the packaging material, encapsulating and leaving the liquid injection port, (iv) injecting a solid electrolyte precursor into the liquid injection port, (v) sealing the liquid injection port, allowing to stand and obtaining the finished product, where the solid electrolyte precursor comprises 2-5 wt.% first polymerized monomer, 3-7 wt.% second polymerized monomer, 1-4 wt.% third polymerized monomer, and 85-94 wt.% the electrolyte. USE - The method is useful for preparing all-solid-state electrolyte battery. ADVANTAGE - The method has simple formula, convenient synthesis, is suitable for large-scale production, and the prepared all-solid-state electrolyte battery has good charging performance and high safety performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for all-solid-state electrolyte battery, obtained by the method as mentioned above.
