　　Differences in safety maintenance between square lithium ion battery cells 18650 and circular lithium ion battery cells 18650

　　Differences in safety maintenance between square lithium ion battery cells 18650 and circular lithium ion battery cells 18650:

　　1. In the past, the key to lithium battery safety protection can be divided into two parts: external refers to threats caused by external forces such as collision and penetration; internal refers to threats caused by heat dissipation and attenuation coefficients.

　　2. In fact, not only square lithium ion battery cells 18650, ring lithium ion battery cells 18650 and soft pack batteries are also widely used in vehicle safety maintenance.

　　Since the internal composition of these three rechargeable batteries is not very different from square and cylindrical lithium ion battery cells 18650, the biggest difference is that the casing of soft-pack batteries is a plastic steel composite bag, while the casings of square and cylindrical rechargeable batteries are made of metal composite materials. .

　　3. Square lithium battery protection solution: When the battery temperature rises abnormally, a high resistance will appear, blocking the battery charging current and ensuring the safe use of the battery.

　　4. Cylindrical lithium battery protection scheme: There is PPTC inside the battery for over-soft over-current protection. When the battery temperature is too high or the current is too high, PPTC will become a high resistance state, thereby blocking the battery charging current and preventing the rechargeable battery from catching fire and exploding. Therefore, when using cylindrical lithium ion battery cells 18650, you must pay attention to the temperature, operating voltage and current.

　　5. Notice that the maintenance concept of lithium ion battery cells 18650 is to: 1) ensure the safety inside and outside the battery pack, including accidental impacts and punctures; 2) to ensure that the battery does not age during the battery cycle, the temperature inside and outside the battery must be monitored.

　　How to store lithium ion battery cells 18650

　　1. The temperature of batteries and battery compartments should be controlled within the range of 20±5°C, the maximum temperature should not exceed 30°C, and the air humidity should not exceed 75%. The warehouse should be kept clean, dry, and well ventilated, and no other objects should be stored.

　　2. Batteries and batteries should be placed neatly and not piled too high. Storage equipment should be made of flame-retardant materials and anti-static measures should be taken.

　　3. If the battery smells, becomes hot, discolors, deforms or has any abnormal phenomena during use, storage and charging, the battery should be removed from the device or charging head immediately and stopped.

　　All in all, cylindrical and hard-packed prismatic batteries have achieved rapid development because they have been well used in their respective applications. Maintenance of lithium ion battery cells 18650 can not only extend the service life of the rechargeable battery, but is also related to the safety of the rechargeable battery. The lithium battery may explode and harm users.

　　Chinese power lithium battery manufacturers predict that Square will become the most popular power lithium battery, but they still need to innovate technically so that the specific energy of vehicle batteries continues to increase and the battery performance becomes even better.
