Abstract
An electrochemical device includes a first electrode assembly, a second electrode assembly, and a packaging shell. The first electrode assembly and the second electrode assembly B are each located in a separate cavity in the packaging shell. Two opposite-polarity tabs of the first electrode assembly and the second electrode assembly are connected in the packaging shell. The connected two opposite-polarity tabs comprise a first tab extending out of the packaging shell. Such design of extending the tabs and the design of ion insulation between the hermetic cavities improve the charge and discharge performance and the product quality of the electrochemical device.
