18650 battery 3500mah lithium.Which is better, polymer lithium battery or 18650 lithium battery?

　　Large capacity polymer lithium battery.

　　For polymer lithium batteries and 18650 rechargeable batteries with the same volume, the polymer volume is very large, about 30% or more. When buying a mobile charger with a large space, it is best to choose polymer lithium batteries, which are lighter.

　　18650 battery is low.

　　18650 rechargeable batteries, generally the most necessary one is 2200mAh.

　　There are three specifications of 2400mAh and 2600mAh, all using mobile chargers with 18650 lithium batteries. Most of the specifications are connected in series with the above types.

　　As you can imagine, an 18650 mobile charger above 8000mAh. The appearance must be larger.

　　Lithium polymer batteries have long life.

　　Lithium polymer batteries can be charged and discharged more than 1,000 times and have the smallest capacity.

　　After 500 charge and discharge cycles of 18650 battery, the volume is reduced by about 30%.

　　Polymer lithium battery lithium battery.

　　Polymer lithium batteries are covered with an aluminum film and a layer of highly wear-resistant medical tape. They will never explode. At most, they may bulge. In the worst case, they may ignite or produce flames. Therefore, compared with 18650, polymer batteries are still very soft.

　　Application of lithium battery 18650.

　　The key to the application of lithium secondary batteries in the industrial production of power energy rechargeable batteries lies in their excellent characteristics. With the continuous development of lithium secondary battery technology, its use in people's daily lives is becoming increasingly common, and reusable rechargeable batteries are increasingly attracting the attention of consumers. We are committed to the power energy battery industry and have a comprehensive grasp of rechargeable batteries, so that we can ensure "affordability". Nowadays, 18650 lithium batteries have certain applications in the following industries.
