Title:
NEGATIVE ELECTRODE SEALING BODY OF SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/197563
Kind Code:
A1
Abstract:
Provided is a negative electrode sealing body of a secondary battery. It comprises: a negative electrode cap, a circuit board module and a sealing ring. A battery housing has a structure of recessed turns at one end close to the negative electrode cap. The circuit board module is located between the turns and the negative electrode cap, and is wedged on one side of the turns. The circuit board module is a plastic flexible circuit board. The sealing ring is a flexible and elastic annular insulation cushion layer, which is arranged in a space between the battery housing, the circuit board module and the negative electrode cap. The part where the sealing ring is in contact with the interior of the battery housing is of arc shape so as to cooperate with the arc structure of the battery housing. A first plating layer is provided at the gap between a side edge of the circuit board module and the battery housing. A second plating layer is provided at the gap between the circuit board module and the turns. The second plating layer extends out by a length along the surface of the circuit board module close to one side of the turns, so as to be in contact with the positive electrode wiring on the circuit board module, thereby realizing the electrical contact between the positive electrode wiring on the circuit board module and the battery housing.
