Description

technical field [0001] The invention relates to the technical field of lithium-ion battery welding, in particular to a welding device for lithium-ion battery processing. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. It has the advantages of high energy density, small self-discharge, high charging efficiency and long service life, and has been widely used in electric tools, digital cameras, mobile phones, notebook computers and other fields. [0003] For example, the patent with ...
