Abstract
The present disclosure provides a lithium-ion battery. In the lithium-ion battery of the present disclosure, the positive electrode plate comprises a first surface and a second surface arranged oppositely along its thickness direction. The first surface is provided with a plurality of first projections at intervals, and the second surface is correspondingly provided with a plurality of first recesses. The height of the first projection is denoted as H µm, and the diameter of the first projection is denoted as R mm, with H and R satisfying 0.2 ≤ H/R ≤ 80. The electrolyte comprises a carboxylic ester, with the mass percentage of the carboxylic ester relative to the total electrolyte mass denoted as A, which satisfies 10 ≤ A ≤ 80. When the above conditions are met, the battery's fast-charging performance and cycle stability can be improved.
