Battery production device and battery production method

Abstract

The invention belongs to the technical field of battery production and manufacturing, and discloses a battery production device and a battery production method. The battery production device comprises a feeding assembly, a lower die assembly, an upper die assembly and a pressing assembly, wherein the upper die assembly includes an upper cover and a lower pressing column, the upper cover is arranged above the feeding assembly, the lower pressing column is arranged on the side, close to the feeding assembly, of the upper cover, and the lower pressing column is arranged in the feeding assembly in a penetrating mode; the pressing assembly includes a pressure maintaining piece and a pressure bearing column, the upper end of the pressure bearing column abuts against pressure controllable equipment, the lower end of the pressure bearing column penetrates through the pressure maintaining piece and then abuts against the upper cover, and the pressure controllable equipment drives the upper die assembly to move relative to the feeding assembly through the pressure bearing column so that the lower pressing column can abut against a medium to be crimped; and the pressure maintaining piece is arranged outside the feeding assembly in a sleeving mode and can slide relative to the feeding assembly so that the inner wall of the pressure maintaining piece abuts against the upper cover. The battery production device reduces the production cost and improves the quality of finished products.

Description

technical field [0001] The invention relates to the technical field of battery production and manufacturing, in particular to a battery preparation device and a battery preparation method. Background technique [0002] At present, solid-state batteries use solid-state electrolytes instead of organic liquid electrolytes for production and manufacturing, which not only has good safety, but also has greater room for improvement in terms of specific energy, specific power density, and cycle performance. [0003] Existing solid electrolytes and all-solid-state batteries are usually constructed by powder molding method, so that current collectors, electrodes and electrolytes form a layered structure. Since the positive and negative electrode materials and solid electrolyte materials require an inert gas as a protected closed environment, during electrochemical characterization (such as charge and discharge experiments, AC impedance, cyclic voltammetry, and DC polarization, etc.), ...

AI Technical Summary

Problems solved by technology

[0004] First of all, because the electrical signal needs to be introduced into the glove box, it is necessary to preset or modify the electrical circuit of the glove box, which brings a lot of inconvenience, difficult processing, and high production cost.

[0005] Secondly, it is necessary to provide a certain accommodation space for the tablet press in the glove box, which is easy to cause space waste

Due to the occupancy of the glove box by the tablet press, when analyzing multiple samples or multiple conditions, for example, experiments under different charging and discharging systems for multiple samples, the multi-channel function of the battery charging and discharging instrument cannot be well utilized. It can only be carried out sequentially, which consumes too much time and greatly reduces the test efficiency

[0006] Thirdly, the battery is easily affected by the outside world, causing short circuit, open circuit, etc., which will affect the quality of the finished product
