Abstract
A battery cell, a battery apparatus, a power consuming apparatus, and an energy storage apparatus are disclosed. The battery cell includes a stacked electrode assembly having a positive electrode plate, a negative electrode plate, and a separator disposed between them. The positive electrode plate includes a current collector and a film layer containing lithium-containing transition metal phosphate particles, at least partly coated with carbon. In a cross-section of the film layer along the thickness direction, 12% to 50% of the particles have a size of 1 μm or greater. The separator includes a base film, ceramic layers on both sides of the base film, and a bonding layer disposed on at least one ceramic layer facing the positive electrode plate. The bonding layer is a continuous porous layer comprising a vinylidene fluoride polymer, which enhances adhesion and thermal stability of the separator.
