Abstract

This invention relates to a core conduction connecting structure for secondary Li cells, in which, the core set is located in the inside of a cell tank, this invention sets a connection connecting piece as a conduction connector between positive or negative leading out terminals on the core and the cell tank and the connecting piece is composed of at least a fixed bolt and a conducting wafer of a flexure member, the either end of which is formed with a connecting end and a connecting part is formed between the two connecting ends set correspondingly outside of the positive or the negative connecting region to get the connecting ends and the connecting region contacted closely and connected electrically, and the connecting part is linked with the leading out terminals of the positive or the negative on the cell tank so as to finish the set of cells smoothly by the flexure buffer of the connecting piece even if there is error in size between the core and the tank.

Description

technical field [0001] A cell conductive connection structure of a secondary lithium battery, in particular the design of the connection structure between the cell inside the secondary lithium battery and the positive or negative lead-out terminal on the battery can. Background technique [0002] Please refer to Figure 1, which is the US patent application No. 11 / 456119, the patent application for the conductive structure of the pole roll of the secondary lithium battery, which was proposed by the inventor of the present case. Forming or welding several conductive handles first, and then welding or connecting them to the lead-out terminals of the battery one by one, resulting in process problems, such as time-consuming and labor-intensive welding operations, complicated component structures, and difficult and complicated manufacturing processes. [0003] Therefore, as shown in FIG. 1 , in this application, one end side of the positive and negative electrode layers of the pol...
