Abstract

The invention relates to the field of energy storage, in particular to an electrochemical device and an electronic device. The electrochemical device includes a shell, an electrode assembly, a conductive sheet, an insulator, and a first connector. The electrode assembly is accommodated in the shell, the electrode assembly comprises a first pole piece, a second pole piece and an isolating membrane,and the isolating membrane is arranged between the first pole piece and the second pole piece. The first pole piece comprises a first current collector, and the second pole piece comprises a second current collector. The first current collector includes a first portion that is an outermost layer of the first current collector in the electrode assembly. The conductive sheet is electrically connected with the second current collector, and the conductive sheet is arranged between the first portion and the shell. The insulator is disposed between the first portion and the conductive sheet. A first connecting piece is connected with the conductive sheet and the shell. According to the electrochemical device and the electronic device provided by the invention, SOC can be reduced under the condition that the temperature rises, the risk caused by thermal runaway can be avoided, and the safety is higher.

Description
