A formation device for lithium battery cells

Abstract

This utility model proposes a lithium battery cell formation device, particularly relating to the field of lithium battery technology. It includes a mounting base with a lithium battery body mounted on its top. In use, the lithium battery body is placed in the placement slot of the mounting frame. Then, a motor is started, driving a bidirectional lead screw to rotate, causing the first and second clamping plates to approach each other, bringing the anode and cathode terminals against the two ends of the lithium battery body, thus forming the lithium battery body. After formation, a connecting plate is pushed upwards, compressing a spring through the connecting plate, which in turn pushes a support plate upwards via a sliding rod. The support plate slides out of the through slot, pushing the lithium battery body out for easy removal. Pulling the connecting plate upwards causes it to contact a latch, deforming the latch and fixing it in place. After removing the lithium battery body, pulling the handle disengages the latch from the connecting plate, causing the spring to return and the support plate to reset.

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium-ion batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are typically non-rechargeable and contain metallic lithium, while lithium-ion batteries do not contain metallic lithium and are rechargeable. In existing technologies, lithium battery formation involves charging the battery immediately after production to activate it, similar to formatting a floppy disk. Only after formation can the battery begin normal charging and discharging. Therefore, a lithium-ion battery cell formation device is needed. Utility Model Content
