Maintenance Instructions For Lithium Battery Aluminum Shell

The lithium battery aluminum shell is a very important part of the lithium battery. It plays an important role in insulation and protection. If you want to extend the battery life and reduce the cost of use, the maintenance and protection of the lithium battery shell is also indispensable. The following is a maintenance instruction for the lithium battery aluminum case, I hope it will be helpful to users.

1. Daily cleaning

Avoid loose loading: When shipping lithium batteries, ensure that the aluminum shell is tightly fixed to avoid loose loading and causing damage.

Regular cleaning: According to the use environment, regularly clean the lithium battery aluminum shell to remove dirt and dust on the surface.

Use a suitable detergent: When cleaning, use warm water containing lubricants or neutral detergents, and avoid using acidic or alkaline detergents to avoid corrosion to the aluminum shell.

Wipe with a soft cloth: Soft cloth and towels should be used as cleaning tools. It is strictly forbidden to use corundum powder, sandpaper, wire brushes or other friction objects to scrub the power battery aluminum case to avoid scratching the surface.

2. Anti-corrosion and protection
Avoid humid environment: The aluminum case of lithium battery should be stored in a dry environment and avoid long-term exposure to humid environment to avoid oxidation and discoloration.
Avoid acid-base environment: Aluminum is easily soluble in dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions. Therefore, the aluminum shell of lithium battery should be avoided in acid-base environment to avoid chemical reaction and performance degradation.
High-quality topcoat protection: After cleaning, the aluminum shell of power battery can be polished with high-quality topcoat protective wax on the anodized film, or a layer of acrylic ester-based varnish can be evenly sprayed to enhance its anti-corrosion ability.

3. Storage and preservation
Suitable temperature: -20\~60°C is the ideal ambient temperature for aluminum storage or use. In extreme environments, aluminum should not be stored or used to avoid deformation, discoloration or corrosion.
Dry and ventilated: Aluminum should be stored in an indoor environment with constant temperature and suitable dryness and humidity to ensure that aluminum will not be oxidized and discolored due to contact with water. At the same time, wooden pallets can be used between aluminum to facilitate ventilation and avoid moisture.
Avoid direct placement: Do not place aluminum directly on the floor. Since the humidity near the ground is greater than that of the upper space, the direct consequence of placing it on the floor is that the aluminum at the bottom will be damp and oxidized.
Half-power storage: Lithium batteries that have not been used for a long time should be charged and discharged once within 3 months, and it is recommended that the single cell voltage be kept within 3.8V~3.95V to maintain battery performance.

4. Precautions for use
Avoid impact: When using lithium batteries, they should be handled with care to avoid impact that may cause deformation of the aluminum shell or even fire.
Avoid overcharging and over-discharging: Lithium batteries must be used within the voltage range of 2.75~4.2V to avoid overcharging or over-discharging to extend battery life.
Timely inspection: When using batteries, you should regularly check whether the battery skin is damaged and whether the battery performance has declined. If there is any abnormality, it should be replaced in time.

In summary, the maintenance of aluminum battery cases requires comprehensive consideration of cleaning, corrosion prevention, storage and use. Through scientific and reasonable maintenance measures, the service life of lithium batteries can be extended and battery performance can be improved, thereby ensuring the reliability and safety of lithium batteries in various application scenarios.
