POSITIVE ELECTRODE, BATTERY, ENERGY STORAGE DEVICE, AND ELECTRICAL CONSUMER DEVICE

Abstract

The invention relates to an anode, a battery, an energy storage device, and an electrical consuming device. The anode consists of a positive current collector. The positive current collector has an anode material layer on at least one surface of the anode. The anode material layer consists of an anode material. The anode material consists of primary and secondary particles. Each secondary particle is a secondary particle formed by the fusion of primary particles. Each secondary particle defines the gaps on the surface of the secondary particle, the secondary particle defines the pores inside the secondary particle, and these pores are connected to the outside through the gaps. The average sphericity of the secondary particles is S, and S satisfies S ≤ 0.6.
