The difference between square lithium battery and round lithium battery in safety maintenance

The difference between square lithium battery and round lithium battery in safety maintenance: 1. In the past, the key to safety protection of lithium battery can be divided into two parts: the outside refers to the threat caused by external force such as collision and penetration; the internal refers to heat removal And the threat caused by the attenuation factor. 2. In fact, not only square lithium batteries, ring-shaped lithium batteries and soft-pack batteries are also mostly common in car safety maintenance. Since the internal structure of these three rechargeable batteries is not very different from square and cylindrical lithium batteries, the big difference is that the casing of the soft pack battery is a plastic-steel composite bag, and the casing of the square and cylindrical rechargeable battery is a metal composite material. . 3. Square lithium battery protection plan method: When the battery temperature rises abnormally, it will show a high resistance to block the battery charging current of the rechargeable battery and ensure the safe use of the rechargeable battery. 4. Cylindrical lithium battery protection plan: there is PPTC inside the rechargeable battery to carry out soft overcurrent protection. When the battery temperature is too high or the current is too high, the PPTC will become a high-impedance condition, which will block the battery charging current of the rechargeable battery, and be alert for the rechargeable battery to catch fire and explode. Therefore, when using cylindrical lithium batteries, be sure to pay attention to temperature, working voltage and current. 5. Informing the maintenance concept of lithium battery is: 1) To ensure the safety inside and outside the battery pack, including accidental impact and penetration; 2) To ensure the battery cycle length, the rechargeable battery is embrittled, the temperature inside and outside of the rechargeable battery must be monitored. Lithium battery storage method 1. The temperature of the rechargeable battery and the rechargeable battery compartment is controlled within the range of 20±5℃, the highest temperature does not exceed 30℃, and the air humidity does not exceed 75%. The warehouse should be kept clean, dry, and naturally ventilated, and cannot be stored Other objects. 2. The rechargeable batteries and rechargeable batteries should be placed neatly and do not need to be stacked too high. The storage equipment should be made of non-flammable raw materials and antistatic measures should be adopted. 3. If the rechargeable battery emits odor, hotness, discoloration, deformation or any abnormal phenomenon during the whole process of use, storage and battery charging, the rechargeable battery should be removed from the machine equipment or charging head and stopped. All in all, cylindrical and hard-packed prismatic batteries have gained a rapid development trend because they have been very well used in their respective critical applications. The maintenance of lithium batteries can not only improve the service life of rechargeable batteries, but is also related to the safety of rechargeable batteries. Lithium batteries are likely to explode and harm customers. my country's power lithium battery processors predict that the decomposition of square will become the popularity of power lithium batteries, but they still need to carry out independent innovation in technology. The specific energy of the whole car rechargeable battery continues to increase, and the battery performance is even more extraordinary.
