Influencing factors of 18650 lithium battery price
1. The relationship between price and capacity of 18650 lithium battery
Capacity is a hotspot for most new users, and the higher the capacity, the higher the cost. We know that the most stable battery capacity range in the entire 18650 lithium battery market is about 2200-3000mah, and the highest battery capacity is about 3200mah. Generally speaking, the higher the capacity, the higher the battery price. Therefore, when you buy cylindrical lithium batteries every day, you must choose a solution that suits your power supply needs, rather than blindly pursuing high-capacity lithium batteries.
2. The relationship between the price of 18650 lithium battery and the internal resistance value
At present, there are not many devices for testing battery capacity and internal resistance in China. For most ordinary families, there is not much time to pay attention to the real parameters of 18650 lithium batteries. However, for the purchasers engaged in the lithium battery procurement business, the understanding of the internal resistance range helps to obtain the final price of the lithium battery more accurately. Generally speaking, the larger the internal resistance and the smaller the capacitance, the lower the price of the 18650 lithium battery and the worse the quality. For those applications that require more power, the resistance is relatively small, and the price of 18650 lithium batteries is naturally relatively high. So another factor that affects the price of a battery is its resistance.
3. The relationship between the price of 18650 lithium battery and the quality of battery shell
It is generally believed that most of the time, the 18650 lithium battery price shell is not sensitive to most battery buyers, but we have to say that the quality of the shell directly affects the final quality stability of the battery. So the quality of the casing will also affect the price of 18650 lithium batteries.
4. 18650 lithium battery price and explosion-proof design Most of 18650 lithium batteries are designed with steel shells, so it is obvious that this kind of battery has the possibility of accidents, so the explosion-proof design can effectively prevent such accidents and even tragedies. . Therefore, explosion-proof design is another factor that affects the price of 18650 lithium batteries.
5. The relationship between 18650 lithium battery price and intelligent battery management system
The price of 18650 lithium battery is to use IC circuit to control its various overcharge, overflow and various protection, but with the continuous improvement of modern technology, high-quality lithium battery is fully capable of designing a suitable intelligent battery management system. The design of the intelligent battery management system is another important factor affecting the price of lithium batteries.
