　　Which is better, polymer lithium battery or 18650 lithium battery

　　Large capacity polymer lithium batteries.

　　Polymer lithium batteries and 18650 rechargeable batteries with the same capacity have a large polymer volume, about over 30%. When choosing a mobile charger with a large space, it is best to choose polymer lithium batteries that are lighter.

　　18650 battery has low power.

　　The most necessary capacity for a 18650 rechargeable battery is generally 2200mAh,

　　There are three specifications of mobile chargers, 2400mAh and 2600mAh, all of which use 18650 lithium batteries. The vast majority of these specifications are connected in series.

　　Imagine an 18650 mobile charger with a capacity of over 8000mAh. The appearance must be larger.

　　Polymer lithium batteries have a long lifespan.

　　Polymer lithium batteries can be charged and discharged more than 1000 times with the smallest capacity.

　　The 18650 battery undergoes 500 cycles of charging and discharging, resulting in a capacity reduction of approximately 30%.

　　Polymer lithium battery lithium battery.

　　Polymer lithium batteries are coated with a layer of aluminum film and then wrapped with a layer of wear-resistant medical tape, which will definitely not cause explosions. At most, there will be air bubbles, and in the worst case, it will ignite and produce flames. Therefore, compared to 18650, polymer batteries are still very flexible.

　　The application of lithium battery 18650.

　　The key to the application of lithium secondary batteries in the industrial production of electric energy rechargeable batteries lies in their excellent characteristics. With the continuous development trend of lithium secondary battery technology, its application in daily life is becoming increasingly common, and rechargeable batteries that can be reused multiple times are receiving more and more attention from customers. Committed to the power energy battery industry, we have a comprehensive understanding of rechargeable batteries, ensuring that they are "affordable". Nowadays, 18650 lithium batteries are widely used in the following industries.
