Abstract: A lithium-ion battery electrode includes a current collector and n electrode plate layers laminated on the current collector, n being an integer greater than or equal to 2. The electrode plate layer contains a pore-forming agent. A content of the pore-forming agent in the electrode plate layers gradually increases along a direction gradually away from the current collector. The pore-forming agent is selected from an electrolyte solution additive which is solid at normal temperature.
