What factors will affect the price of 18650 lithium-ion batteries?

1] Lithium-ion battery capacity We understand that capacity is a hotspot of lithium-ion batteries that most novice users are most concerned about. Generally, the higher the capacity, the more expensive it is. We understand that the most stable battery capacity in the current 18650 lithium-ion battery market is roughly in the range of 2200-3000mah, and the highest can be measured at about 3200mah. Therefore, when you buy cylindrical lithium-ion batteries daily, you must choose a method that suits your power supply needs, not blindly chasing high-capacity lithium-ion batteries. [2] The internal resistance of lithium-ion batteries. We understand that there are not many household equipment for testing battery capacity and internal resistance. Most ordinary families do not have so much time to pay attention to the real parameters of lithium-ion batteries. However, for purchasing personnel engaged in the procurement of lithium batteries, grasping the range of internal resistance helps to obtain the final price of lithium-ion batteries more accurately. Generally, the larger the internal resistance, the smaller the corresponding capacity. Regarding those operating environments with higher power requirements, the resistance value is relatively small, and the price is naturally relatively high. So another price influence factor of the battery is its resistance value. [3] Battery case I believe that most of the time, the battery case is not sensitive to most battery purchasers, but what we have to say is that the quality of the case directly affects the final quality of the battery. Therefore, the quality of the shell also affects its price. [4] Explosion-proof design We understand that since most of the current 18650 lithium-ion batteries are designed with steel shells, there is obviously the possibility of accidents in these batteries, so the explosion-proof design can effectively curb such accidents and even tragedies. . Therefore, whether there is an explosion-proof design is another reason that affects the price of lithium-ion batteries. [5] Intelligent battery management system We understand that most of the time, most lithium-ion batteries use IC circuits to control their various overcharge, overcurrent, and various protections. However, with the continuous improvement of modern technology, high-quality lithium-ion batteries Fully capable of designing a suitable intelligent battery management system. The design of this intelligent battery management system is another important factor affecting the price of lithium-ion batteries.
