Introduce the characteristics of 18650 batteries

What is the characteristic of the 18650 battery? The 18850 battery has a fixed shape, which is the middle and low end of the battery field. It doesn't look like. 5Battery. Generally, the field is installed in a cylindrical steel shell with liquid lithium ion electrolyte inside. The 18850 battery can only be a graphic bar. If you are buying a large shape of a mobile power supply, you can basically use the 18550 battery. Polymer lithium ion battery has large capacity Compared with 18650 battery of the same volume, polymer lithium ion battery has a larger capacity, which is more than 30% higher. If you want to buy a large-capacity power bank, you'd better choose a polymer battery, which is thinner and more portable. The 18650 battery capacity is small. The 18650 battery capacity is generally 2200mAh, 2400mAh and 2600mAh. The 18650 cellular power bank is basically a parallel connection of the above specifications. It is conceivable that the 18650 mobile power supply is above 8000 mA. The shape must be larger. Life-span polymer lithium ion battery VS18650 battery The polymer lithium ion battery can be charged and discharged more than 1000 times with the smallest capacity. The 18650 battery is cycled more than 500 times, and the capacity is reduced by about 30%. Safety polymer lithium ion battery VS18650 battery polymer electric oil is covered with a layer of aluminum film, and then covered with a layer of strong tape, it will not explode, at most only air drums will appear, and the most evil is burning and flame. Therefore, compared with 18650, polymer battery is still very flexible. Due to the special nature of the 18550 battery packaging (using steel shell), short circuits are prone to occur. If the product quality is not up to standard, the biggest risk is explosion. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
