AI Technical Summary

Technical Problem

During the manufacturing process of secondary batteries, the loss of active materials leads to a reduction in battery capacity, and existing technologies are unable to effectively reduce this loss.

Method used

The secondary battery manufacturing equipment includes a winding section, a conveying section, and a processing section. The active material layer of the electrode plate is precisely grooved through thickness measurement and differentiated processing. A laser generator and a blower are used to reduce the loss of active material.

Benefits of technology

By precisely controlling the grooving process of the active material, the loss of active material is reduced, thereby increasing the battery capacity of the secondary battery and improving the battery quality and defect rate.

Abstract

A secondary battery manufacturing apparatus and method are disclosed. A secondary battery manufacturing apparatus includes a winding section including an unwinding machine and a winding machine, an electrode plate to be unwound from the unwinding machine, and the electrode plate to be wound on the winding machine. A conveying section includes a roller configured to support the electrode plate as the electrode plate moves from the unwinding machine to the winding machine. A processing section includes a first processing section disposed in a path along which the electrode plate moves from the unwinding machine to the winding machine and disposed at a first surface of the electrode plate, and a second processing section disposed at a second surface of the electrode plate. Using the secondary battery manufacturing apparatus and method according to the present disclosure, loss of active material can be minimized. And using the secondary battery manufacturing apparatus and method according to the present disclosure, capacity of a secondary battery can be increased.
