Formation and capacity grading conjoined plate of soft package battery and formation and capacity grading method thereof

Abstract

The invention discloses a formation and capacity grading conjoined plate of a soft package battery and a formation and capacity grading method thereof. The formation and capacity grading conjoined plate comprises a lower plate body, an upper gland plate and a wiring port, and the upper gland plate is rotationally connected with one end of the lower plate body; the wiring port is fixedly connectedwith the other end of the lower plate body; a battery accommodating groove is formed in the center of the lower plate body; resistance heating wires are distributed at the bottom of the battery accommodating groove; two ends of the resistance heating wire are electrically connected with the wiring port; wiring grooves are respectively formed in two sides of the battery accommodating groove; a plurality of tab positioning groove bodies which are parallel to one another are connected between the wiring grooves in the two sides; two groups of tab connecting poles are arranged at the bottom in thetab positioning groove body, tab abdicating openings are formed in two sides of the tab positioning groove body, tabs of the soft package battery penetrate through the abdicating openings to be electrically contacted with the tab connecting poles, the tab connecting poles are connected with leads, and the leads are led out from the wiring groove. Formation, shaping and capacity grading are integrated, frequent battery loading and unloading are not needed, the production process is greatly simplified, and cooperation with automatic assembly line operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a soft-pack battery forming and containing integrated board and a forming and containing method thereof. Background technique [0002] The soft pack lithium battery is covered with a polymer shell on the outer layer of the liquid lithium ion battery. In terms of structure, it is packaged with aluminum-plastic film. In the event of a safety hazard, the soft-pack battery will only explode with air at most. [0003] The production process of pouch batteries includes processes such as formation, shaping, and capacity separation. Each process requires placing and removing batteries. The operation is cumbersome, which not only wastes time, but also increases work intensity, which is not conducive to automatic operation. [0004] Therefore, the present application designs a pouch battery chemical composition and capacity conjoined board and its chemical composition and capacity metho...
