Which is better, polymer lithium battery or 18650 battery

Which is better, polymer lithium battery or 18650 battery? Polymer lithium battery polymer lithium battery polymer battery, light Grosvenor Co., Ltd. battery side beautiful appearance, shape can be customized, ultra-thin battery, such as 0.25 mm, Therefore, polymer batteries and mobile power sources can also be designed with more spirit in appearance. Now many smart wear equipment batteries use lithium polymer batteries, which can make their products more fashionable and more free in appearance design. 18650 lithium battery 18650 lithium battery 18850 battery is fixed and formed. It is a low-end product in the battery field. It doesn't look like. 5Battery. 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 battery has large capacity Compared with 18650 battery of the same volume, polymer lithium 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 battery capacity of the 18650 is very small. Generally, the battery capacity of the 18650 is 3 kinds of 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. Lifetime polymer lithium battery VS18650 battery The polymer lithium 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 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, there will be air drums. The most evil thing is burning and flame. Therefore, compared with 18650, polymer battery is still very flexible. Due to the special nature of the 18550 battery package (using a steel shell), short circuits are prone to occur. If the product quality is not up to standard, the biggest risk is explosion.
