Are polymer lithium-ion batteries and 18650 lithium-ion batteries comparable?

1) Are polymer lithium-ion batteries and 18650 lithium-ion batteries comparable? 1. Polymer battery materials are more complicated. The 18650 lithium-ion batteries are relatively simple. Which of the polymer and 18650 is more complicated? It is worthy of warning, and the safety is also Not absolute. High-quality 18650 batteries are much safer than inferior polymer batteries, so consumers still have to keep their eyes open for identification. Under the condition of quality assurance of batteries, the volume of 18650 will be larger than that of polymers, so From a portable point of view, polymer batteries will be relatively lighter. Polymer or 18650 is more complicated. Relatively speaking, there are many polymer battery models and specifications. Different battery models have different battery capacities and battery specifications. They are not familiar with the customization method of polymer lithium-ion batteries. For demanders, polymer batteries are much more complicated. 2. The 18650 can be assembled with a large capacity, while the polymer battery single-cell capacity 18650 lithium-ion battery is relatively simple, because its battery models are basically the same, but the battery capacity of the battery brand is different. Different 18650 battery manufacturers research and develop different brands of takeaway 18650 lithium batteries, usually with 2200mAh, 2400mAh, 2600mAh, and 2800mAh capacity standards. According to industry insiders, the 18650 has achieved the largest single-cell capacity of 3400mAh at this stage. If the mobile charger uses 18650 as the battery core, basically the above specifications are connected together. Nowadays, the more famous ones are several imported batteries, such as sung batteries, Hisense batteries, and Konka. Batteries, etc., while the price of domestic 18650 batteries is relatively more convenient than imported batteries. 3. Which is more complicated polymer battery or 18650 polymer battery with a layer of aluminum plastic film and a layer of high temperature tape. The greatest safety of polymer is leakage, short-circuit failure, and the worst case. The situation is the formation of burning, forming a flame. So compared with 18650, polymer batteries are better in terms of safety. But burning can also bring hidden dangers to safety accidents. Therefore, it is recommended that users who use mobile chargers should try not to place mobile chargers on pillows or bedside places. 2) Advantages of 18650 lithium battery 1. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model aircraft, toys, camcorders, digital cameras and other electronic equipment. 2. The series connection can be connected in series or in parallel to form a 18650 lithium ion battery pack. 3. Small internal resistance. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. , It can reach the level of international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen batteries. 4. There is no memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 5. High voltage 18650 lithium-ion battery voltage is generally 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 6. High safety performance 18650 lithium-ion battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; all kinds of safety performance are completed in one go, and the number of cycles is greater than 500; high temperature resistance performance, 65 degrees The discharge efficiency reaches 100%. In order to prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium-ion battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to prevent overcharge and overdischarge of the battery, which can also extend the service life of the battery. 7. Long service life The 18650 lithium ion battery has a long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 8. The capacity of 18650 lithium ion battery with large capacity is generally between 1200mah~3600mah, while the general battery capacity is only about 800. If 18650 lithium ion batteries are combined to form a 18650 lithium ion battery pack, the 18650 lithium ion battery pack is casual It can break through 5000mah. 1. The 18650 is more durable. The battery capacity is larger, which is more durable than the polymer or the 18650. The important thing depends on the application field. If a Bluetooth sports headset is durable even if the 18650 battery is durable, it will not fit in. However, if the size is not limited, I personally recommend it. 18650, relatively more durable. 2. Polymer battery materials are more complicated. The 18650 lithium-ion battery is relatively simple, which is more complicated, polymer or 18650. It is worth warning that safety is not absolute. High-quality 18650 batteries are much safer than inferior polymer batteries, so consumers still have to keep their eyes open for identification. Under the condition of quality assurance of batteries, the volume of 18650 will be larger than that of polymers, so From a portable point of view, polymer batteries will be relatively lighter. Polymer or 18650 is more complicated. Relatively speaking, polymer batteries have more models and specifications. Different battery models have different battery capacities and battery specifications. They are not familiar with the customization method of polymer lithium-ion batteries. For demanders, polymer batteries are much more complicated. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
