What is the capacity of a common 18650 lithium battery?

Common 18650 lithium batteries are divided into lithium batteries and lithium iron phosphate batteries. The voltage of lithium battery is 3.6V and 4.2V, the voltage of lithium iron phosphate battery is 3.2V, the capacity is usually 1200mAh-3000mAh, and the common capacity is 2200mAh-3600mAh. The 18650 lithium battery capacity is the key selling point of the manufacturer. In addition, the 18650 lithium battery cell brand with the same capacity is also a factor affecting the price. Generally speaking, imported brands are more expensive than domestic brands of the same type. As mentioned earlier, 18650 lithium batteries are decided. The important factor of capacity is the structure of raw materials. Therefore, from the perspective of the positive electrode, the price of lithium cobalt oxide, lithium manganate and ternary materials, and lithium iron phosphate will be different. Due to the fixed size of the 18650 lithium battery, its maximum capacity has always attracted the attention of many practitioners. In recent years, various manufacturers have improved their technology, and the capacity has increased accordingly. Samsung, Panasonic, LG, Sony, and Toshiba can achieve more than 3600mAh. , But the best stability and consistency is the capacity range of 2600~3000mAh. If it is a battery pack, it is best not to use the highest capacity. Both the cost performance and the service life of the battery pack after the group are not very cost-effective, so it is not the battery. The higher the capacity, the more stable it will be used for a long time. 18650 lithium batteries are generally divided into capacity type and rate type. The capacity type mainly reflects the large capacity, but the discharge current is generally lower than 1C, and the current is small; the rate type can discharge at a large current, but the capacity is low, and the use time is not long. The price of 18650 lithium battery is directly proportional to the capacity. The larger the capacity, the greater the energy ratio, and the more raw materials used, so the price will be more expensive. The general price is 10~30 yuan/piece.
