3.7v 18650 battery pack

　　Which performance is better between polymer lithium battery and 18650 lithium battery

　　1. The raw materials of polymer lithium batteries are very complicated, while 18650 lithium batteries are relatively simple.

　　Polymers and 18650 are very complex and very amazing and are not safe. High-quality 18650 lithium-ion batteries are much safer than fake polymer batteries, so customers still need to use their eyes to identify them. Polymers and 18650 are very complicated. There are relatively many types of polymer lithium batteries. Different types of batteries have different battery capacities and battery specifications. I don’t understand the needs of polymer lithium battery customization solutions for batteries. Lithium-ion batteries are more complex.

　　Lithium-ion batteries have a magnetic coil of metallic material and a flammable lithium-ion battery fluid in which fragments of the metallic material float. The contents of a rechargeable battery are under operating pressure, so if a piece of metallic material breaks through a barrier separated by a durable object, or if a rechargeable battery is penetrated, sometimes the lithium ions are killed due to the high temperatures generated by the reaction of lithium with water in the air. Activated, Li-ion displays high power output with small net weight, Li-ion battery components are designed to be dominant, which means that the thin system distinguishes the rechargeable battery and the thin case. These battery plates and coatings are sensitive, they can be punctured, if the battery is damaged, a short circuit failure can occur, a spark can ignite a lithium-based enzyme, another possibility is. Lithium can be heated to levels that cannot be controlled thermally, where the heat generated stresses the rechargeable battery.

　　2. The 18650 can be assembled with a large capacity, and the capacity of a single polymer battery

　　18650 lithium-ion batteries are relatively single, because the battery models are the same, but the battery brands have certain differences. Different 18650 rechargeable battery manufacturers develop and deliver 18650 lithium-ion battery core brands, generally 2200mah, 2400mah, 2600mah, 2800mah volume specifications. According to 360 professionals, the current 18650 guarantees a large capacity of 3400 Mach. If the mobile charger uses 18650 as the lithium-ion core, it will be connected together based on multiple models. At present, a batch of imported lithium-ion batteries are more famous, such as Sung batteries, Hisense batteries, Konka batteries, etc., while domestic 18650 batteries The price is relatively more convenient than the price of imported lithium-ion batteries.

　　3. There is a layer of aluminum plastic film on the outside of the polymer lithium battery and 18650 lithium battery, and a layer of high-temperature rubber cloth. The high safety factor of the polymer is the common fault of leakage and short circuit faults, resulting in high packaging and extreme cases. Ignition , Produce flames. So polymer cores are safer than some cores compared to 18650. However, ignition can also cause safety hazards, so it is recommended that mobile phone charger users try not to put mobile phone charger pillows and bedroom beds in certain places.
