Abstract

The present application discloses an electrode manufacturing method, a battery, and an electrical apparatus. The electrode manufacturing method comprises steps of: providing a slurry mixed with a pore-forming agent; coating the slurry on a current collector to form an active material layer on the current collector; and electrically energizing the active material layer to cause the pore-forming agent in the active material layer to undergo an electrochemical reaction to form pores. Before the step of coating the slurry on the current collector, the method further comprises a step of: providing a roller configured to coat and convey the current collector and provided with a conductive member on a surface of the roller, the conductive member being configured to electrically connect to the current collector. The step of electrically energizing the active material layer comprises electrically energizing the current collector through the conductive member. The technical solutions provided in the present application can improve the pore-forming efficiency of the electrode, thereby enabling, when the electrode is used in the battery, the battery to have relatively high manufacturing efficiency.
