Opening formation method for soft package lithium ion battery production

The invention discloses an opening formation method for soft package lithium ion battery production, which synchronously exhausts in the formation process and comprises the following steps: (1) clamping a battery cell; (2) pressing by a clamp; (3) performing formation electrification; (4) performing air bag adsorption; (5) piercing the air bag; (6) performing battery cell formation; (7) finishingformation; (8) pricking and sealing; (9) balancing air pressure; (10) standing for capacity grading; (11) opening the clamp; and (12) taking out the battery cell, and carrying out subsequent secondarysealing and trimming processes. By using the method, exhaust is synchronously performed in the formation process in the battery production process, so that the equipment investment cost of separate treatment is reduced, the formation time is shortened, and the production efficiency is improved. 本发明公开了一种软包锂离子电池生产的开口化成方法，化成过程中同步进行排气，包括以下步骤：(一)电芯装夹；(二)夹具压合；(三)化成通电；(四)气袋吸附；(五)刺穿气袋；(六)电芯化成；(七)化成完成；(八)刺口密封；(九)气压平衡；(十)静置分容；(十一)夹
