System and method for manufacturing special-shaped three-dimensional battery cell

Abstract

The invention discloses a system and a method for manufacturing a special-shaped three-dimensional battery cell, and relates to a system and a method for manufacturing a secondary battery. The method mainly comprises the steps of preparing pole pieces, preparing a diaphragm, stacking the pole pieces, laminating and forming and the like. The system mainly comprises a positioning mechanism, a stacking mechanism and a transferring mechanism, and automatic high-precision battery cell forming processing is carried out. According to the invention, the battery cell with any irregular shape can be manufactured in a completely personalized customization manner, the negative plates are used as the outer contour shape of the battery cell, the maximization of the electric quantity of the battery cell can be realized, the positive plates can be completely clamped between the two adjacent negative plates, the safe operation of the battery cell can be realized, the product consistency is high, and the product has the characteristics of high yield and wide application prospect. The process is simple and efficient, automatic battery cell manufacturing can be achieved, the yield of special-shaped battery cells is effectively increased, and the problem that batteries in the market are limited by the space of applied products is effectively solved.

Description

technical field [0001] The invention relates to the field of secondary battery manufacturing systems and methods, in particular to a manufacturing system and method for a special-shaped three-dimensional battery cell that can be used for manufacturing soft-packed lithium-ion batteries with high energy density, high safety performance, and strong shape plasticity. Background technique [0002] At present, secondary batteries, especially soft-pack lithium-ion batteries, are widely used in various electronic products, especially mobile phones, computers, and wearable products, due to their high energy density, high safety performance, and strong shape plasticity. With the continuous application and promotion of secondary batteries in various electrical appliances, batteries with standard shapes in the past can no longer meet the needs of the market, such as wearable and household electronic products, the shape of the battery often needs to obey the design needs of the product, a...
