Abstract

The present application discloses a current collector disc processing method, a current collector disc, a battery cell, and an electrical apparatus. The current collector disc processing method includes: a punching step of providing a first sheet stock; a stacking step of providing a second sheet stock and stacking the second sheet stock with the first sheet stock; a welding step of welding the first sheet stock and the second sheet stock in a welding region; and a cutting step of obtaining the current collector disc. According to the current collector disc processing method, the current collector disc, the battery cell, and the electrical apparatus provided in the present application, the current collector disc is obtained by sequentially undergoing the punching step, the stacking step, the welding step, and the cutting step, and does not require positioning structures to be arranged on an annular sheet and a connecting disc, which is conducive to simplifying the structure of the current collector disc, improving the positional accuracy of the annular sheet and the connecting disc in the current collector disc, and simplifying the production and assembly process of the current collector disc.
