Abstract
A partition plate includes a partition substrate, a positive electrode membrane, a negative electrode membrane, and an insulation layer. The positive electrode membrane and the negative electrode membrane are respectively located on two surfaces of the partition substrate. The insulation layer is disposed on the partition substrate and the insulation layer is disposed at a periphery of the positive electrode membrane. A zone surrounded by orthographic projection of an outer edge of the insulation layer on the partition substrate covers orthographic projection of the negative electrode membrane on the partition substrate. This application can improve self-discharge and safety performances of electrochemical apparatuses.
