Price analysis of 18650 lithium ion battery

The price of 18650 lithium ion battery, how long is the life of 18650 lithium ion battery? The capacity of 18650 lithium ion battery can now reach 2500mAh, and the charging rate of the battery can be used and discharged normally at 2C. The 18650 lithium-ion batteries on the market are a mixture of different types of batteries, and there are big differences in pricing and sales positioning according to different brands and models. Therefore, we have to choose the most suitable one according to the specific situation. 18650 lithium-ion battery price analysis 18650 is the standard lithium-ion battery model adopted by Sony, the originator of lithium-ion batteries in Japan, in order to save costs. 18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery. Ordinary 18650 batteries are divided into lithium ion batteries and lithium iron phosphate batteries. The voltage of the lithium ion battery is 3.6v and 4.2v, and the voltage of the lithium iron phosphate battery is 3.2v, and the usual capacity is 1200mAh-3000mAh and 2200mAh-3600mAh. 18650 lithium-ion battery.

Different boards can be divided into several types of products, pricing, they have certain differences, light weight, large capacity, no memory effect, etc. Li-ion batteries in 18650 play a very important role. In many cases, this also makes, Starting a large number of inferior products on the market, because consumers without relevant background knowledge, how to correctly choose the most suitable machine, it becomes very important. Advantages of 18650 lithium ion battery 1. Large capacity, the capacity of 18650 lithium ion battery is generally between 1200mah~3600mah, while the general battery capacity is only about 800. If the 18650 lithium ion battery is combined with the 18650 lithium ion battery pack, 18650 lithium The ion battery pack can exceed 5000mah at will. 2. Long service life: The 18650 lithium ion battery has a long service life. Under normal use, its cycle life can reach more than 500 times, which is more than twice that of ordinary batteries. 3. High safety performance, high safety 18650 lithium ion battery, no explosion, no burning; non-toxic, non-polluting, RoHS trademark certification; various safety performance, more than 500 cycles; high temperature resistance, 65 degrees power efficiency up to 100 %. In order to prevent short circuits, the positive and negative electrodes of the 18650 lithium-ion battery are separated. Therefore, the possibility of its short circuit has been reduced to the limit. You can add a protective panel to prevent the battery from being overcharged, which can extend the life of the battery. 4. High voltage: The voltage of 18650 lithium ion battery is generally 3.6v, 3.8v, 4.2v, which is much higher than the 1.2v voltage of nickel-hydrogen nickel-cadmium battery. How long is the life of 18650 lithium ion batteries? At present, the general cycle life of 3.7v18650 lithium ion batteries can reach 500~1000 times, and the general life of 3.2v18650 lithium ion batteries can reach more than 2000 times. Of course, the premise is that the regular manufacturers produce qualified batteries. If the battery is defective or fake, the life span will be very short. The service life of 18650 lithium ion batteries is generally 300 to 500 recharges. Assuming that the power supplied by a complete discharge is Q, if the reduction in power after each charging cycle is not taken into account, lithium can supply or supplement 300q-500q of power during its service life. From here we understand that if you use 1/2 charge each time, you can charge 600-1000 times. If you charge 1/3 each time, you can charge 900 to 1500 times. By the same token, if the battery is charged randomly, the number of times of charging will also change. In any case, no matter how you charge, you can always get 300Q to 500Q of energy, which is a constant. Therefore, we can also understand that the life of a lithium-ion battery is related to the total power of the battery, and has nothing to do with the amount of power. Deep charge and shallow charge have the same impact on the life of lithium-ion batteries. The theoretical life of a ternary lithium-ion battery is about 800 times, which makes it a medium for commercial rechargeable lithium-ion batteries. Lithium iron phosphate has about 2,000 cycles, while lithium titanate is said to be able to reach 10,000 cycles. Currently, mainstream battery manufacturers promise to exceed 500 times their ternary battery specifications. However, after the battery pack is matched into a battery pack, the important reason is that the voltage and internal resistance cannot be exactly the same.
