Document Type and Number:
WIPO Patent Application WO/2021/135166
Kind Code:
A1
Abstract:
Disclosed are an energy storage device and a method for assembling the energy storage device. The energy storage device comprises an energy conversion element, a housing and a terminal; the energy conversion element is provided with at least one electrical connection part, which is arranged on a surface of the energy conversion element; a cavity is formed inside the housing, the housing comprises a first half housing body and a second half housing body, which are connected together in a sealed manner, and at least one of the first half housing body and the second half housing body comprises a concave structure and a surrounding edge part, which is formed by the edge of the concave structure extending outwards; the concave structure is provided with a windowed structure; and the terminal is of a sheet-shaped structure, the edge of at least one surface of the terminal is in sealed connection with the windowed structure, and the electrical connection part comes into contact with an inner surface of the terminal. The present invention has the technical effect of realizing an electrical connection between the energy conversion element and the outside by means of the terminal, a battery has the characteristics of both a soft pouch and a steel housing, the process is simple and the safety performance is high, the terminal and the housing are in sealed connection, and when the internal pressure of the housing increases, pressure can be relieved at a joint between the terminal and the housing, such that the safety performance is improved.
