Battery is not only an essential electrical appliance in our lives, but also one of the sources of environmental pollution. Therefore, batteries must be properly disposed of after use, sorted with waste and recycled in an environmentally friendly manner. Some people may have heard of putting batteries in the refrigerator to extend their life, but does this method really work? How to put the battery in the refrigerator correctly?
In fact, putting the battery in the refrigerator can actually extend its life, especially for nickel-metal hydride batteries and nickel-cadmium batteries. When a battery is exposed to high temperatures, internal chemical reactions accelerate, causing the battery to lose capacity. Placing the battery in the refrigerator can slow down the chemical reaction, extending the life of the battery.
CHowever, if this method is not used correctly, it will cause damage to the battery, including the possibility of the battery case being stained by water vapor, causing internal corrosion of the battery, poor conductivity and reduced lifespan. , or even damage to the battery. Therefore, before placing the battery in the refrigerator, you should pay attention to the following points:
1. Battery type: Metal hydride batteries and nickel-hydrogen batteries can be placed in the refrigerator, but lithium batteries are. not recommended for use in the refrigerator.
2. Storage temperature: The suitable storage temperature is about 15℃. Too low a storage temperature may cause the battery to expand or leak, affecting its use.
3. Packing method: plastic bags or sealed bags should be used to wrapthe battery to avoid moisture.
4. Storage duration: Batteries that are not used for a long time should be stored in the refrigerator and charged regularly to prevent battery self-discharge.
In short, properly placing the battery in the refrigerator can extend its life, but you also need to pay attention to factors such as storage temperature, packaging method and storage time . Most importantly, when a battery reaches the end of its lifespan or fails, it must be disposed of properly and recycled in an environmentally friendly manner.
How to store batteries?
Battery negative electrode materials can be stored in boxes. When lithium batteries are produced, graphite powder is used to make negative electrode sheets. In order to facilitate transportation and storage, grap powderhite will be filled in storage boxes. storage. , but the existing storage box does not have a drying device, and the graphite powder will contain moisture. At the same time, humidity in the air will also penetrate into the graphite powder during long-term storage, causing the graphite powder to be stored. become wet, which will cause the graphite powder to deteriorate; Therefore, a storage box for lithium battery negative electrode materials is proposed to solve the above problems
Lithium battery storage height requirements
< p>Daily maintenance of lithium batteries:
1. The newly purchased lithium battery will have a certain power, so users can use it directly when they receive it, use the energy remaining, then charge it. . After 2-3 times of normal use, the activity of the lithium battery may befully activated. Here's a special reminder: don't believe the seller or internet rumors. New lithium batteries should be activated for up to 12 hours when first used.
2. Lithium batteries have no memory effects and can be charged at any time. However, it should be noted that lithium batteries cannot be over-discharged, causing irreversible loss of capacity. When the machine reminds you that the battery is low, it immediately begins charging.
3. In daily use, freshly charged lithium batteries should be left aside for half an hour until the charging performance is stable before use, otherwise the battery performance will be affected.
4. When not using the instrument, be sure to remove the battery and store it in a dry, cool place.
5. Pay attentionNote the usage environment of lithium batteries: the charging temperature of lithium batteries is 0°C ~ 45°C and the discharge temperature of lithium batteries is -20°C ~ 60°C. .
6. Do not mix batteries with metal objects to avoid metal objects touching the positive and negative terminals of the battery, causing a short circuit, damaging the battery or even causing danger.
7. Do not hit, acupuncture, step on, modify or expose the battery to sunlight, or place the battery in a microwave, high voltage or other environment.
8. Use a matching lithium battery charger to charge the battery. Do not use inferior or other types of battery chargers to charge the lithium battery.

How to store lithium batteries when not in use fora long time
1 When lithium batteries are not used for a long time, they should be charged to 50% to 80% of their capacity and removed from the instrument. Store in a dry and cool environment, and charge the battery every 3 months to prevent the battery from becoming too low due to self-discharge, resulting in irreversible capacity loss. .
2. Self-discharge of lithium batteries is affected by ambient temperature and humidity. High temperature and humidity will accelerate the battery's self-discharge. It is recommended to store the battery in a dry environment. 0? ℃ and 20? ℃.
No. There are no height requirements for stacking lithium batteries. Warehouse requirements require dryness, coolness, ventilation, emergency lighting, safety exits, concrete structures and fire-fighting equipment. Stacking requires fixed supports andshould not exceed 5 layers. It should not be placed sideways or vertically. It should be placed horizontally, and the cells and batteries should be placed in categories. The storage requirements are that the storage temperature must be below 30 degrees, not exceeding the minimum and maximum temperatures specified by the manufacturer, and the storage power must be maintained between 30% and 50%.
