18650 battery 3500mah.Which one has better performance, polymer lithium battery or 18650 lithium battery?

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

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

Lithium-ion batteries have a metallic electromagnetic coil and a flammable lithium-ion battery liquid in which metal fragments 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 Activated, lithium-ion displays high power output with a small net weight, and the lithium-ion battery component is designed to be dominant, which means that the thin system distinguishes the rechargeable battery and the thin case. These panels and coatings are sensitive, and they can be punctured. If the battery is damaged, a short-circuit failure can occur, and a spark can ignite the lithium-based enzyme, another possibility. The lithium may be heated to levels that cannot be thermally controlled, where the heat generated stresses the rechargeable battery.

2. 18650 has a large assembly capacity and a polymer battery has a single cell capacity.

The 18650 lithium-ion battery is relatively single, because its battery model is the same, but the battery brand has 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 Mach 3,400. If the mobile charger uses 18650 as the lithium-ion core, it will be connected together based on multiple models. Currently, the more famous ones are a batch of imported lithium-ion batteries, 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 an aluminum plastic film on the outside of the polymer lithium battery and 18650 lithium battery, and there is a layer of high-temperature rubber cloth. When the polymer encounters a large safety factor, it is a common fault of leakage and short circuit failure, resulting in high packaging, and in extreme cases, ignition. , produce flame. So compared to 18650, the polymer core is safer than some cores. However, ignition can also cause safety hazards, so it is recommended that mobile phone charger users try not to place mobile phone charger pillows and bedroom beds in certain places.


Which one is more durable, polymer lithium battery or 18650 lithium battery?

1. 18650 lithium battery is resistant to falling

The 18650 type lithium-ion battery is a cylindrical battery, while the polymer lithium battery is a special or prismatic battery. Polymer lithium batteries are coated with aluminum plastic films, which are sensitive to the outside world and can be easily scratched. If the polymer lithium-ion battery is accidentally dropped to the ground, the rechargeable battery ears can easily break. The cylindrical rechargeable battery of the 18650 is made of a metal casing, which is not a problem

2. The same necessary conditions as the polymer cycle

If both polymer and 18650 rechargeable batteries are made of the same ternary material, storage requirements for polymer and 18650 rechargeable batteries, storage requirements for polymer and 18650 rechargeable batteries, polymer and 18650 rechargeable batteries The application requirements, the application requirements of 18650 and polymer lithium batteries, and the necessary conditions for 18650 and polymer circulation systems are all the same. In fact, in most cases it is unclear which one is the durability of 18650 and polymer lithium batteries.

3. 18650 is more durable and has a larger battery capacity.

The key to the durability of polymer lithium batteries and 18650 lithium batteries is to see the main use. If the mobile phone Bluetooth fitness exercise or even the 18650 battery can no longer be put into the battery for durability, I don’t know the specific situation. I recommend using 18650, which is more durable.
