Publication number: 20250210660Abstract: This application provides a lithium supplement slurry, a positive electrode slurry, a secondary battery, a secondary battery preparation method, and an electrical device. The lithium supplement slurry includes a lithium supplement additive and a phosphate ester compound. The lithium supplement slurry uses a phosphate ester compound as a solvent. The phosphate ester compound is stable at a normal temperature, and does not react with the lithium supplement additive. Therefore, in a positive electrode slurry that uses the phosphate ester compound for supplementing lithium, the phosphate ester compound does not make the positive electrode slurry prone to gel, but makes the slurry meet performance requirements on an industrial mass-produced slurry, and makes it easy to apply the slurry to form a coating layer. In addition, the phosphate ester compound is of low toxicity and high safety in production.Type: ApplicationFiled: February 6, 2025Publication date: June 26, 2025Inventors: Yue Xu, Keqiang Li, Bin Xie, Shitong Chen
