Performance comparison of polymer battery and 18650 battery

Which is the most durable polymer battery or 18650 battery? 1, polymer battery and battery durable shape first, 18650, 18650, belong to cylindrical lithium ion battery, polymer battery alien, or square, using polymer battery aluminum plastic film The packaging is relatively fragile on the outside, easy to scratch, pits, and broken skin. If you accidentally put the polymer battery, the battery anode ear is easy to break. The 18650 cylindrical battery is wrapped in a metal shell and can be flipped several times at will without any major problems. Two 18650 batteries, polymer batteries are durable: if all use the same ternary polymer material, and the conditions of 18650 batteries, polymer batteries and battery charging and discharging conditions, and conditions to use polymer batteries in 18650 and 18650 , 18650 battery, polymer battery cycle conditions are the same, similar standard voltage standard structure and the same working environment, in fact, basically said 18650 battery, polymer battery and durable. 3. Whether the 18650 battery or polymer battery is durable depends on the application scenario. If the Bluetooth headset is also equipped with the durability of the 18650 battery, but the size of the case is not limited, it is recommended to use the 18650, which is more durable. Which is the more expensive polymer battery or 18650 battery? 1. The price of polymer battery and 18650 battery is expensive mobile power with 5000mAh battery. 18650 needs at least two 2600 in parallel to reach 5000mAh, and polymer can reach 5000mAh. Change within the size range. Let it be the shape you want; but for the 18650, only Panasonic Sanyo monomer can reach a maximum of 3200 mAh, and a polymer battery of 5000 mAh can be purchased. 2. The price of the same polymer is much more expensive, such as domestic: 5000MAH polymer price is 35 yuan, 18650 or even two parallel prices are 27 yuan, but 18650 is more risky than polymer batteries, and it is easy to explode, I recommend choosing polymerization Safety first. If the 18650 lithium-ion battery and polymer lithium-ion battery are both well-structured, then find the reason for the charger. Generally, the charging current should be set according to the 18650 and polymer battery specifications. 18650 battery or polymer battery which is better? 1.18650 Li-ion battery is better or polymer battery is really difficult to draw conclusions. However, no matter how good the battery is, it can easily break if used improperly. However, polymer batteries are much more complicated. In addition to considering the safety of normal electrical performance, the appearance of the packaging assembly and the possibility of the positive earrings breaking during the packaging process should also be considered. 2. From a consumer's point of view, the advantages of 18650 batteries and polymer batteries may be more beneficial to polymer batteries. The burning probability of the 18650 battery is lower than that of the 18650 battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
