These powders are specially processed and used to coat the electrodes of batteries. The cathode powder usually includes an oxide, such as lithium cobalt oxide. The negative electrode powder is usually a carbon-based material. The lithium battery powder directly affects the performance, capacity, and charge and discharge capabilities of the battery. Therefore, it plays an indispensable key role in lithium battery manufacturing.

Storage Conditions of Lithium Battery Powder

The storage conditions of lithium battery powder are critical to ensure their quality and performance. Powders should be stored in sealed packages to avoid the ingress of moisture and oxygen. They should stay away from direct sunlight to prevent humidification, oxidation, or aggregation of the powder. In addition, maintaining the uniformity of the powder and preventing impurities from entering are also critical. Therefore, vacuum packaging is the best way to pack and store lithium battery powder.

The Importance of Vacuum Packaging to the Preservation of Lithium Battery Powder

  • Moisture Protection: Lithium battery powder is very sensitive to moisture. Moisture absorption will cause the powder to agglomerate, condense, or reduce quality. Vacuum packaging can effectively reduce the entry of moisture and keep the powder dry. The dry state is critical to maintaining powder performance and stability.
  • Oxidation Protection: Oxygen can cause oxidation reactions in lithium battery powders, especially for some metal oxide powders. Vacuum packaging can reduce the chance of oxygen contact, reduce oxidation reactions, and ensure the quality of the powder.
  • Long-term Storage: Lithium battery powder needs to be stored for a long time to prepare for future production. Vacuum packaging can extend the life of the powder and reduce the quality changes of the powder during storage.
  • Powder Uniformity: Vacuum packaging helps maintain powder uniformity and prevent stratification or agglomeration of powder materials.
  • Prevent Impurities: Vacuum packaging can reduce the chance of external impurities entering the powder and maintain the purity of the powder. Impurities can negatively affect battery performance.
