What are the requirements for customizing 18650 lithium batteries.
Nowadays, there is an increasing demand for customized lithium batteries, which are designed for devices with special requirements for lithium batteries. Currently, lithium batteries have been applied in various industries. Generally, the lithium battery products we use in our daily lives do not need to be customized. What needs to be customized are industrial grade lithium batteries.
What is customized lithium battery?
Battery customization is a highly technical activity that involves evaluating a new battery model based on the specific needs of the customer. Compared to traditional standardized cylindrical batteries such as 1865021700, it requires consideration of the battery factory's production process, material control, and whether they have rich experience in solutions. General situation
Next, we will customize based on the five major requirements provided by users:
1. Battery shape
You can customize the size and shape of the battery, in addition to the different dimensions of length, width, and height, it can also be made into various shapes such as circular, trapezoidal, triangular, etc.
2. Capacity
Calculate whether the battery capacity can meet the user's battery life requirements based on the power consumption of the product.
3. Magnification ratio
Some special products have certain requirements for magnification, such as electronic cigarettes, drones, emergency starting power supplies for cars, and electric supercars. High current charging and discharging performance is the primary consideration for batteries, meeting the needs of fast charging or high explosive power.
4. Temperature
The optimal operating temperature for lithium batteries is about 25 ℃, with a general operating temperature range of -20 ℃ to 50 ℃. However, if in special high and low temperature environments, the capacity of lithium batteries will rapidly decline, affecting their lifespan and even rendering them unusable. Therefore, special customized high-temperature or low-temperature lithium batteries are required. Like Haizhitong in low-temperature batteries.
There is rich experience in the field and many mature low-temperature lithium battery solutions, with a minimum temperature of -55 ℃, to meet the electricity needs of special industries.
5. Voltage
The full charge voltage of a typical lithium battery is 4.2V. In order to improve energy density and longer battery life, more and more product designers are using high-voltage lithium batteries (LiHv). For example, Apple's latest series of phones use 4.35V high-voltage lithium polymer batteries to increase battery life. However, this depends on the electrical appliances and PCB design.
