What is the purpose of 18650 lithium battery?
As we all know, those who have a little understanding of batteries know that although lithium batteries are a new type of battery in the battery industry, they can also be divided into many types such as polymer lithium batteries, 18650 cylindrical lithium batteries, and ternary lithium batteries. Cylindrical lithium batteries are one of the typical representatives of lithium batteries.
Advantages of cylindrical lithium iron phosphate batteries
1. The unity of monomers is relatively good; Cylindrical lithium batteries have already established a series of internationally unified standard specifications and models, with mature and complete processing technology, suitable for large-scale batch uninterrupted production and manufacturing
2. The material of the monomer itself has good mechanical properties, with a large specific surface area of the cylinder and excellent heat dissipation effect of the heat pipe, which can achieve high bending strength;
3. The technology application is mature and complete, and the cost is relatively low. The metal shell of the battery has high pressure resistance, making it less prone to situations such as square or flexible packaging battery swelling during the entire operation process
4. The individual energy is small, and the probability of multiple accidents is low. When an accident occurs, the form is easy to control, and cylindrical batteries are usually sealed batteries, so there will be no maintenance issues during the entire operation process
5.18650 rechargeable battery has no memory, and the remaining power may not be discharged before charging, making it more convenient to use; Low internal resistance, minimal irreversible volume damage, can greatly reduce the power consumption of rechargeable batteries and improve battery life;
6.18650 lithium batteries have a high safety factor and are not prone to explosions, explosions, or environmental pollution. Experimental data shows that due to the separation of the positive and negative poles of ternary lithium batteries, the probability of short circuit faults is reduced to the optimal state in most cases. The protective plate of polymer batteries can repair ternary lithium batteries, which can prevent overcharging or power loss of rechargeable batteries.
Disadvantages of cylindrical lithium iron phosphate batteries:
1.The processing technology for welding multi pole ears in cylindrical lithium batteries is limited, resulting in slightly weaker rate characteristics and less outstanding rate performance.
2. The organic chemical specificity at the corners of cylindrical batteries is poor, and the performance of batteries decreases significantly after long-term operation.
3. Poor compatibility with common batteries is due to the fact that lithium-ion batteries can only be used for replacement when using three common batteries (3.6V).

18650
lithium batteries are more complete and stable worldwide, and their market share is also a leading technology for other lithium-ion products. They have been widely used in the fields of small and medium-sized lithium batteries such as consumer digital electronics, industrial equipment, medical instruments, etc. They are also used in the power lithium battery fields of intelligent robots, AGV logistics vehicles, drones, and new energy vehicles, as well as in the digital category (smartphones, tablets, laptops, electric toy cars, MP3/MP4, headphones, mobile phone power banks, model airplanes, mobile chargers, etc.) It has shown strong development potential.
The Performance and Function of 18650 Lithium Battery
A material that is relatively balanced in terms of capacity and safety, with better cycling performance than normal lithium cobalt oxide. Due to technical reasons, its nominal voltage was only 3.5-3.6V in the early stage, which limited its range of use. With continuous improvement of the formula and structural perfection, the nominal voltage of the battery has reached 3.7V, which has reached or exceeded the level of lithium cobalt oxide batteries in terms of capacity.
