Abstract
A battery includes a negative electrode, a separator, a positive electrode, and an electrolyte. The electrolyte includes a first additive with a structural formula (1), where R1 is selected from a group consisting of H, CH, and CH, and R2 is selected from a group consisting of H, CH, and CH, with n satisfying 1≤n≤10. A mass fraction w1 of the first additive in the electrolyte satisfies 0.01%≤w1≤2%. A mass fraction of lithium supplement particles in a positive active layer of the positive electrode is w3, the lithium supplement particle includes a matrix and a coating layer, a plane shrinkage rate α of the matrix satisfies 0.4≤α×w3/w1≤1.7. A chemical formula of the matrix is LiMNOB, with r satisfying 0.1<r<6.1, p satisfying 0≤p<0.99, and s satisfying 0≤s<0.1.
