A kind of battery preparation device and battery preparation method

Abstract

The invention belongs to the technical field of battery production and manufacture, and discloses a battery preparation device and a battery preparation method. The battery preparation device includes: a feed assembly; a lower mold assembly; an upper mold assembly, the upper mold assembly includes an upper cover and a lower pressure column, the upper cover is arranged above the feed assembly, and the upper cover is close to the feed assembly. One side is provided with a lower pressure column, and the lower pressure column is penetrated in the feed assembly; the pressing assembly includes a pressure retaining part and a pressure bearing column, and the upper end of the pressure bearing column abuts against the pressure controllable equipment, and the pressure bearing column The lower end passes through the pressure-holding part and abuts against the upper cover. The pressure-controllable device drives the upper mold assembly to move relative to the feed assembly through the pressure-bearing column, so that the lower pressure column can press against the medium to be crimped, and the pressure-holding part is pressed. It is configured to be sleeved on the outside of the feeding assembly and be able to slide relative to it, so that the inner wall of the pressure-maintaining member abuts against the upper cover. The battery preparation device reduces production costs 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
