Abstract: A battery includes a positive electrode plate, a negative electrode plate, an electrolyte solution, and a separator between the positive electrode plate and the negative electrode plate. The positive electrode plate includes a positive current collector and a positive material layer disposed on the positive current collector. The negative electrode plate includes a negative current collector and a negative material layer disposed on the negative current collector. The positive electrode plate and the negative electrode plate are configured to have a strong liquid retention capability for the electrolyte solution that can reduce the occurrence of lithium plating during charging.

Abstract: An electrode plate includes an electrode active material layer. The electrode active material layer includes a three-dimensional conductive network base, and an electrode active material and a binder that are loaded on the three-dimensional conductive network base. The three-dimensional conductive network base and the electrode active material satisfy a relational expression below: d × 6 ⁢ D 2 × ( m ρ / π ⁢ D 3 6 ) ≤ V ≤ ( D 3 - π ⁢ D 3 6 ) × ( m ρ / π ⁢ D 3 6 ) where V is an actual volume of the three-dimensional conductive network base, whose unit is cm3; m is mass of the electrode active material, whose unit is g; D is a D50 particle size of the electrode active material, whose unit is μm; ρ is true density of the electrode active material, whose unit is g/cm3; and d is a thickness of a single layer carbon atoms with a value of d is 0.334 nm.
