Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery production, in particular to a lithium ion battery capping and edge wrapping machine. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is intercalated and deintercalated between the two electrodes: when charging, Li+ is deintercalated from the positive electrode and intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; when discharging, the opposite is true. Lithium-ion battery was first successfully developed by Sony Corporation of Japan in 1990. It embeds lithium ions into carbon (petroleum coke and graphite) to form a negative electrode (traditional lithium batteries use lithium or lithium alloy as the negative electrode). LixCoO2 is commonly used as the positive electrode material, and LixNiO2 and LixMnO4 are also used. The electrolyte uses LiPF6+diethylene carbonate (EC)+dimethyl carbonate (DMC).

[0003] However, in the prior art, when the lithium-ion battery cap is hemmed, a punching machine is generally used to punch up and down to complete the hemming. Such an operation process is complicated and cumbersome, and it takes a lot of time. In addition, the long-term up and down punching, without a buffer structure, will cause damage to the explosion-proof plate and affect the quality of the cap. Utility Model Content
