What are the factors that affect the capacity and price of the 18650 lithium-ion battery pack? The 18650 lithium-ion battery ranges in capacity from 1000mAh to 3000mAh. As the market is particularly hot, but also led to today's 18650 lithium-ion battery prices are very messy. 18650 lithium-ion battery pack capacity is the concern of many industrial users and consumers, this is because the greater the capacity of 18650 lithium-ion battery, the longer the use of time, can supply power for users for a longer time.
What are the important factors affecting the capacity of the 18650 lithium-ion battery pack?
The capacity of the monomer is clearly affected by the degree of aging. As we all know, the capacity attenuation to a limit is when the battery is eliminated, so there is an absolute correlation between the two. Secondly, the capacity is also affected by temperature. Under low temperature, the activity of the active substance decreases, and the ion supply becomes less, so the capacity will inevitably decrease.
18650 lithium ion battery pack capacity is an important selling point of manufacturers, in addition, 18650 lithium-ion battery batteries of the same capacity brand is the influencing factors of price, in general, import brands than the same type of domestic brand price is high, the front said, decided that 18650 lithium ion battery capacity and raw material structure, the important factors and from the point of the anode, The price of lithium cobalt acid, lithium manganese acid and ternary materials, lithium iron phosphate will be different.
Because the capacity of the dominant use of the price, the 18650 lithium-ion battery pack capacity on the market will have a false standard phenomenon, such as the capacity of 2200mAh 18650 lithium-ion battery capacity is marked as 2600mAh, which is to deceive consumers, capacity is often caused by artificial nutrition, so users should identify the authentic manufacturer's brand.
Lithium ion battery pack capacity reduction, in addition to the aging and decline of the cell itself, there is a more common, more critical factor, is the self-discharge rate is different, resulting in series battery power imbalance, eventually lead to lithium ion battery capacity reduction and durability.
What are the factors affecting the price of 18650 lithium-ion battery packs?
1.18650 lithium-ion battery pack capacity
We understand that capacity is a hot spot for most new users, and the higher the capacity, the more expensive the battery will be. We understand that the most stable battery capacity range of the entire 18650 lithium-ion battery pack market is approximately 2200-3000mAh, and the highest can be measured around 3200mAh. Therefore, in your daily purchase of cylindrical lithium ion batteries must choose a suitable method for their own power supply needs, and not blindly chase high capacity lithium ion batteries.
2. Internal resistance value of lithium ion battery
We do not know much about the battery capacity and internal resistance detection of home devices, the vast majority of ordinary households do not have that much time to pay attention to the real parameters of lithium-ion batteries. However, for the procurement personnel engaged in the procurement of lithium electricity, the interval grasp of the internal resistance is conducive to more accurate acquisition of the final price of lithium ion batteries. Usually, the larger the internal resistance, the smaller the capacity. For those operating environments that require higher power, the resistance value is relatively small, and the price is naturally relatively high. So another factor that affects the price of a battery is its resistance.
3. Battery housing
I believe that most of the time, the battery shell is not sensitive to most battery purchasing personnel, but we have to say that the quality of the shell directly affects the final quality of the battery stability. So whether the shell is good or not also affects its price.
4. Explosion-proof design
We know that most of the current 18650 lithium-ion battery packs are designed with steel shell, so there is obviously the possibility of accidents in this kind of battery, so the explosion-proof design can effectively prevent the occurrence of such accidents and tragedies. So whether there is explosion-proof design is also another reason that affects the price of lithium-ion batteries.
5. Intelligent battery management system
We know that most of the time, lithium ion battery pack mostly uses IC circuit to control its various overcharge, overcurrent, all kinds of protection, but with the continuous improvement of modern science and technology, high-quality lithium ion battery is fully capable of designing a set of appropriate intelligent battery management system. The design of this smart battery management system is another key factor affecting the price of lithium-ion batteries.
Important consists of batteries, the price of the lithium ion battery protective plate and shell parts, at the same time due to the power consumption and size of the current electric appliances, the batteries of the connection between the material selection will affect the cost of different connectors are also likely to impact on the cost is larger, and the different PACK process will also affect the cost.
The above is the important factors affecting the capacity and price of the 18650 lithium ion battery package. The length of the use of lithium ion battery is important to depend on the capacity of the lithium ion battery. The higher the voltage of the lithium ion battery, the greater the capacity, that is, the stronger the load capacity.
