Problems solved by technology

After the lithium-ion battery is dropped, due to the impact of the free electrolyte on the diaphragm, the diaphragm is prone to folding, which will easily lead to a short circuit between the positive and negative electrodes, which has a greater safety risk; and the diaphragm folding will also cause the voltage of the lithium-ion battery to drop , performance degradation

Abstract

The present application provides an electrochemical device, which includes an electrode assembly and a casing for accommodating the electrode assembly. The electrode assembly includes a pole piece, a separator, and a first adhesive member. The pole piece includes a first pole piece and a second pole piece with opposite polarities, the first pole piece and the second pole piece are stacked and arranged, and the isolation film is used for isolating the first pole piece and the second pole piece. The outermost layer of the isolation film includes a first part, and in the thickness direction of the electrode assembly, the projection of the first part is separated from the projection of the pole piece. The first part is extended from the part of the isolation film between the adjacent first pole pieces and the second pole pieces, and the first adhesive member adheres the outer surface of the outermost pole piece of the electrode assembly and the first part. The present application also relates to an electronic device. By adopting the above electrochemical device, the short circuit problem caused by the folding of the diaphragm can be improved.

Description

technical field [0001] The present application relates to the technical field of battery manufacturing, and in particular, to an electrochemical device and an electronic device. Background technique [0002] Terminal devices such as mobile phones often fall, and the drop performance of the built-in lithium-ion battery has become a safety performance that people pay close attention to. After the lithium-ion battery falls, due to the impact of the free electrolyte on the diaphragm, the diaphragm is prone to fold, which can easily lead to a short circuit between the positive and negative plates, which poses a greater safety risk; and the folding of the diaphragm will also lead to a drop in the voltage of the lithium-ion battery. , the performance is reduced. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide an electrochemical device and an electronic device, aiming at improving at least one problem existing in the prior art. [0004] Embodiments ...
