Abstract
The present disclosure relates to a lithium ion battery including an electrode assembly; and an electrolytic solution for infiltrating the electrode assembly and an electrical apparatus including the same, wherein the electrode assembly includes an electrode body, a positive electrode tab, and a negative electrode tab. The electrode body includes a positive electrode plate, a negative electrode plate, and a separator that are wound together around an axis. The positive electrode plate includes a positive current collector and a positive electrode material layer provided on at least one surface of the positive electrode current collector. In an axial direction (X), the electrode body has two opposite side portions, and the positive electrode tab and the negative electrode tab extend from the two side portions of the electrode body, respectively. A diffusion rate v of the electrolytic solution to the electrode body is from 0.01 μg/s to 5 μg/s.
