Brief description of the capacity of 18650 lithium battery

The capacity of 18650 lithium battery is the personal concern of many industrial users and consumers. This is because the larger the capacity of 18650 lithium battery, the longer the use time, which can provide users with longer power supply. However, under the same system, 18650 The high capacity of lithium batteries will bring negative uses of high prices, so the balance between capacity and price is very important. Among the above-mentioned battery processing manufacturers, the capacity of 18650 lithium batteries is distributed between 1000mAh and 3000mAh, but the more mature technology is generally between 1800mAh and 2600mAh. This is because the capacity of 18650 lithium batteries is too low, which will affect the effective working time of the battery. , There are problems in applicability. However, if the capacity of 18650 lithium battery is too high, the cost will increase greatly, and the significance of 18650 lithium battery with too high capacity in non-special category is not very great. In the case that the battery volume has been fixed, the method to increase the capacity of the 18650 lithium battery is mainly to add the active material and increase the specific capacity of the active material. The 18650 lithium battery capacity increase is a historical process, from 600mAh in the 1990s to the current 3000mAh. In the process of increasing the capacity of 18650 lithium batteries, Japanese companies have made outstanding contributions. The 18650 lithium battery capacity is the key selling point of the manufacturer. In addition, the 18650 lithium battery cell brand of 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. Because of the dominant use of capacity on price, the capacity of 18650 lithium batteries on the market will have a false standard. For example, the capacity of 18650 lithium batteries with a capacity of 2200mAh is marked as 2600mAh. This is an act of deceiving consumers. Therefore, users should look for authentic manufacturers' brands. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
