Introduction to the advantages and characteristics of 18650 lithium-ion batteries

Generally speaking, 18650 lithium ion batteries have the following advantages: 1. Wide application coverage: notebooks, wireless walkie-talkies, portable DVDs, instruments and equipment, professional audio equipment, aviation models, small toys, digital cameras, digital cameras and other electronic products. 2. The series connection of 18650 lithium-ion battery packs can be connected in series or in parallel. 3. Low internal resistance. The internal resistance of the polymer core is lower than that of the liquid core. The internal resistance of the domestic polymer transformer skeleton is below 35m, which greatly reduces the functional loss of the battery, adds the battery life on the mobile phone, and completely achieves the level of docking with the world. This type of polymer lithium battery suitable for high-current charging and discharging is an ideal choice for remote operation and is the most anticipated product to replace nickel-hydrogen batteries. 4. There is no reminiscence utility. It is not necessary to clear the remaining power before charging the battery, which is convenient to use. 5. High working voltage The working voltage of 18650 lithium-ion battery is 3.6V, 3.8V and 4.2V respectively, far exceeding nickel-cadmium battery and nickel-hydrogen battery. 6. High safety use 18650 lithium ion battery has high safety use, no explosion, no ignition; non-toxic, zero pollution, according to RoHS brand certification; various safety uses are carried out at one time, and the frequency of the circulation system is 500 times. Top; Good heat resistance, 100% charge and discharge output power at 65°C. In order to better prevent battery short-circuit failures, the positive and negative stages of the 18650 lithium-ion battery were separated. Therefore, the probability of short-circuit failure is likely to have already fallen to the limit. A lithium-ion battery protection board can be installed to prevent excessive battery charging and increase battery life. 7. Long service life 18650 lithium ion battery has a long service life. The cyclic system service life of 18650 lithium-ion batteries in all normal applications is more than 500 times longer than that of ordinary batteries. 8. Large volume The volume of 18650 lithium-ion batteries is generally between 1200mAh~3600Mah, and the average battery volume is only 800. If the 18650 lithium-ion battery is composed of a 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack is very easy to penetrate 5000 Mach.
