Abstract
A secondary battery includes a positive electrode plate. that includes a positive current collector, a first positive active material layer distributed on one side of the positive current collector, and a second positive active material layer distributed on an other side of the positive current collector and a negative electrode plate that includes a negative current collector, a first negative active material layer distributed on one side of the negative current collector and opposite to the second positive active material layer, and a second negative active material layer distributed on an other side of the negative current collector. A resistance of the first positive active material layer is R1, a resistance of the second positive active material layer is R2, a resistance of the first negative active material layer is R3, a resistance of the second negative active material layer is R4.
