18650 lithium ion battery 3.7v

　　Will polymer 18650 lithium ion battery 3.7v explode?

　　Most of today's polymer 18650 lithium ion battery 3.7v are plastic soft-pack rechargeable batteries, and the plastic shell is aluminum-plastic film. When organic chemical lithium battery electrolytes are used internally, explosions will not occur even if the liquid is hot. Because the aluminum-plastic film polymer lithium battery is a solid or colloidal solution, there is no leakage, only natural rupture. However, everything is uncertain. If the instantaneous current is large enough to cause a short circuit, the battery may catch fire or explode. Most of the safety accidents of smart phones and laptops are caused by this kind of situation.

　　The service life of polymer 18650 lithium ion battery 3.7v is generally several years.

　　Scientific and standardized statement: The service life of lithium battery is closely related to the number of battery charging cycles, but not directly related to the number of battery charging cycles. With each battery charging cycle, the power consumption will decrease a little. However, the decrease is very small. High-quality batteries can still maintain 80% of the original power consumption after charging the system several times. This is why many lithium-powered products have remained in use for the past year or two. Under national standards, the service life of a rechargeable battery is not expressed by time, but by the frequency of cycles, that is, the rechargeable battery is fully charged and discharged once. The average lithium battery life is between 500-800 times, and the A-class polymer lithium battery can achieve 800 times. Therefore, if you choose a good rechargeable battery dealer, the quality of the rechargeable batteries will be guaranteed and the service life may be longer.

　　The service life of lithium polymers is closely related to the characteristics of the two. Polymer lithium battery is also called polymer lithium battery. Judging from the appearance and appearance, the polymer lithium battery is an outer packaging box with a plastic steel casing, which is different from the plastic casing of liquid 18650 lithium ion battery 3.7v. Plastic steel casings are often chosen. The key is that polymer 18650 lithium ion battery 3.7v use some colloidal solution chemicals to help the rechargeable battery pole pieces adhere to or absorb the lithium battery electrolyte, thus greatly reducing the use of liquid lithium battery electrolyte.

　　With the improvement of structure, polymer 18650 lithium ion battery 3.7v have the advantages of high energy density, better usability and thinness. Compared with liquid 18650 lithium ion battery 3.7v, polymer 18650 lithium ion battery 3.7v have a longer service life, at least 500 cycles.

　　In fact, shallow charging and discharging are more beneficial to 18650 lithium ion battery 3.7v. The power supply of the product only needs to be charged and discharged deeply when calibrating the lithium battery. Therefore, products with lithium battery systems do not need to be subject to the operation process, which saves time and effort. They can be charged at any time without worrying about affecting the service life.
