A Static electricity may cause damage to the internal structure of solid-state batteries. For example, electrostatic discharge may penetrate the solid electrolyte layer, resulting in small cracks or defects inside the electrolyte, especially at the interface between the lithium metal negative electrode and the solid electrolyte. This may damage the interface structure, promote the growth of lithium dendrites, and increase the risk of short circuits; And performance degradation, static electricity may change the surface chemical state of electrode materials, reduce active sites, directly affect the battery's charge and discharge capacity and rate performance, and reduce energy density and power density. The glove box can integrate a static electricity removal device, which can effectively solve the impact of static electricity on the development of solid-state batteries.

A Oxygen can trigger oxidation reactions, alter the crystal structure of the positive electrode material, affect charge and discharge efficiency, and cause capacity loss when reacting with the negative electrode under abnormal conditions. It can also affect thermal stability, exacerbate heating, and even lead to thermal runaway; Moisture reacts with electrolytes to generate corrosive hydrofluoric acid, which damages the structure of electrode materials, affects conductivity, and shortens the battery cycle life; Other impurity gases such as carbon dioxide may react with lithium to form deposits that affect lithium ion transport, and nitrogen may also react with battery components at high voltages, all of which can reduce battery performance. The glove box can create an isolated, controllable, water free, oxygen free, and pure atmosphere environment, which is conducive to the research and development of lithium batteries.

A In the production of lithium batteries, glove boxes are filled with inert gases (such as argon or nitrogen) inside to control the atmosphere. The gas purity requirement is high, for example, the purity of argon gas needs to be above 99.999% to reduce impurity gases. At the same time, strict humidity control is implemented, usually below 1ppm, to prevent moisture from entering the battery components, thereby avoiding adverse effects of oxygen, moisture, and other impurity gases on the battery materials.

A If the water oxygen value of the glove box is high after regeneration, the following measures can be taken: re regeneration and adjustment of relevant parameters (such as extending the time and increasing the temperature), inspection and repair of the sealing performance of the glove box, pre-treatment of the materials inside the glove box to reduce water oxygen release, calibration of water oxygen detection instruments to ensure their accuracy, and strengthening the daily maintenance of the glove box, including maintaining internal cleanliness and strictly controlling material entry and exit. Through these methods, the water and oxygen content inside the glove box can be effectively reduced, ensuring the stability of the experimental and production environment.

A The common reasons for the high water oxygen value after glove box regeneration include incomplete regeneration (such as insufficient heating temperature, insufficient vacuum time, or insufficient purity of inert gas), poor sealing (damaged or aged glove box seals), material release of water oxygen (water oxygen molecules released after the glove box material absorbs moisture), and detection instrument errors (inaccurate display of water oxygen detection instruments).

A The single station glove box is suitable for small laboratories and single person operation scenarios. It can meet the processing needs of air and moisture sensitive materials, such as battery assembly, chemical experiments, etc. The dual station glove box is suitable for scenarios that require collaboration among multiple people and different operating environments. It can provide larger operating space and more functions to meet complex experimental and production needs, such as large-scale assembly and testing of batteries, simultaneous preparation, characterization, and testing of materials by multiple people in materials science research, as well as operations that need to be performed separately in sterile and non sterile environments in biomedical experiments.
