Description

Technical Field

[0001] The utility model belongs to the technical field of lithium ion batteries, in particular to a battery welding fixture. Background Art

[0002] Lithium-ion battery is a secondary battery that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charge and discharge process, Li+ is embedded and de-embedded back and forth between the two electrodes: when charging, Li+ is de-embedded from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state. The opposite is true during discharge. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops all use lithium-ion batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium as electrodes and are the representative of modern high-performance batteries.

[0003] The existing circular lithium-ion batteries need to be fixed with a clamp during the welding process. The clamp of the circular battery is prone to shaking during the welding process, which reduces the fixing effect, causing the battery to break away from the clamp and cause damage.
