Document Type and Number:
WIPO Patent Application WO/2024/095855
Kind Code:
A1
Abstract:
Provided is a lithium ion secondary battery manufacturing method that is characterized by having: a charge/discharge processing step for performing charge/discharge processing of a first lithium ion secondary battery that includes a positive electrode, a first liquid electrolyte, and a negative electrode, said positive electrode having a positive electrode active material layer that includes a sulfur-modified compound; and an exchange step for exchanging the first liquid electrolyte for a second liquid electrolyte after the charge/discharge processing step, to obtain a second lithium ion secondary battery, wherein the first liquid electrolyte includes a solvent selected from the group consisting of saturated cyclic carbonate compounds and saturated straight-chain carbonate compounds, and the second liquid electrolyte includes a solvent selected from the group consisting of saturated cyclic ether compounds and saturated straight-chain ether compounds.
