Abstract

This application discloses an electrochemical apparatus and an electrical device. The electrochemical apparatus includes a housing and an electrode assembly. The housing includes a first housing portion and a second housing portion with opposite polarities. The electrode assembly includes an electrode plate assembly, a first tab, and a second tab, where the electrode plate assembly includes a first electrode plate and a second electrode plate arranged in a wound manner, the first tab is connected to the first electrode plate and the first housing portion, and the second tab is connected to the second electrode plate and the second housing portion. The electrochemical apparatus further includes a first connector, the first connector including a first arc portion and satisfying: 30° ≤ γ + (10.95 × (R₁/R₀)³ - 31.0144 × (R₁/R₀)² + 28.88 × (R₁/R₀) - 7.012) × β₁ ≤ 180°; and/or, the electrochemical apparatus further includes a second connector, the second connector including a second arc portion and satisfying: 30° ≤ γ - (10.95 × (R₂/R₀)³ - 31.0144 × (R₂/R₀)² + 28.88 × (R₂/R₀) - 7.012) × β₂ ≤ 180°. This application facilitates the reduction of an axial magnetic field at an end face of the electrode plate assembly with a wound structure, thereby facilitating the reduction of interference of the electrochemical apparatus on the electrical device.
