Advantages and disadvantages of 18650 lithium batteries.
1. The working standard voltage of 18650 lithium batteries is generally 3.6V, 3.8V, and 4.2V, far exceeding the 1.2V working standard voltage of nickel cadmium and nickel hydrogen batteries.
2. Without memory ability, there is no need to relax with the remaining power consumption before charging the battery, which is convenient and fast.
3. Low internal resistance: The internal resistance of polymer battery cells is lower than that of general liquid lithium battery cells. The internal resistance of Chinese polymer battery cells can even ensure below 35m Ω, greatly reducing the battery's self consumption and improving the battery life of mobile phones. It can fully guarantee the level of global connection. This type of high polymer lithium battery with a large total charge and discharge capacity is also a rational choice for remote control models, becoming the most promising product to replace nickel hydrogen batteries.
4. Can be connected or serially connected to form an 18650 lithium battery pack.
5. Widely used in electronic devices such as laptops, wireless intercoms, portable DVDs, electrical instruments, technical professional audio equipment, model airplanes, toys, surveillance cameras, digital cameras, etc.
Customized production and processing of lithium batteries
Defects:
1. The major disadvantage of 18650 lithium batteries is that their capacity has long been fixed and cannot be accurately positioned when installed in some laptops or products. Of course, this disadvantage can also be called an advantage, as it is a disadvantage compared to other polymer lithium batteries that can be customized and have variable specifications. And relativity is different from some special cases
For products with battery model specifications, it has become an advantageous subsidiary.
2. 18650 lithium batteries are prone to short circuit faults, common malfunctions, or explosion events, which is also relative to high polymer lithium batteries. If the relativity is average, this disadvantage is not so obvious.
3. 18650 lithium battery production and processing must have maintenance routes to prevent the battery from being overcharged and causing charging and discharging. Of course, this is the best approach for lithium batteries, which is also a common drawback of lithium batteries. The raw materials used in lithium batteries are mostly lithium cobalt oxide batteries, and lithium batteries made from cobalt oxide batteries cannot be charged and discharged with high total current, resulting in poor safety performance.
4. The production and processing standards of
18650 lithium batteries are high, which is relatively different from general battery production and processing. 18650 lithium batteries have high production and processing standards, which undoubtedly increases production costs.
