  "textContent": "An electrolyte includes an additive, where the additive includes a first additive M, and the first additive Mis at least one selected from the group consisting of a fluorinated carbonate compound and a compound containing a sulfur-oxygen double bond. The negative electrode includes a negative electrode active material layer, where the negative electrode active material layer includes a negative electrode active material, and the negative electrode active material includes a hard carbon material. The electrochemical device of the present application has improved high-temperature cycling performance, low-temperature performance, and rate performance while maintaining the specific capacity of the negative electrode active material.",
