METHOD FOR PRE-LITHIATION OF NEGATIVE ELECTRODE FOR ALL-SOLID-STATE SECONDARY BATTERY AND SECONDARY BATTERY USING SAME

WIPO Patent Application WO/2020/226324

A1

An all-solid-state secondary battery according to the present invention has a positive electrode, a negative electrode, and a solid electrolyte formed between the positive electrode and the negative electrode, wherein the negative electrode is formed by performing a pre-lithiation procedure in which a powder mixture for forming the negative electrode is grounded with a lithium metal, before assembly of the battery. Due to such a pre-lithiation procedure, no irreversible capacity is observed, and thus the initial efficiency of the battery is improved, and through a simplified process, mass production and cost reduction can be attained.
