Lithium primary button cell, preparation method thereof, and electronic device

Abstract

Provided are a lithium primary button cell, a preparation method thereof, and an electronic device. The lithium primary button cell includes a cell housing (10) and a cell core assembly located within the cell housing (10). The cell core assembly includes a negative electrode (3), a negative electrode modification film (4), separators (5, 6), and a positive electrode (7) that are stacked sequentially. The surface of one side of the negative electrode (3) facing the negative electrode modification film (4) is formed with a concave groove (9) into which the negative electrode modification film (4) is tightly embedded. In the present application, the structure and materials of the lithium primary button cell are optimized so that the lithium primary button cell can have excellent discharging performance and good stability and reliability.
