The price of 18650 lithium-ion power battery, the capacity of the battery is getting larger and more expensive?
18650 lithium ion battery can be divided into capacity type and multi-purpose type. Battery recycling line The type of capacity is very important for large capacity, but the discharge current is usually less than 1C, and the current is very small. The price of 18650 lithium ion battery is directly proportional to its capacity. The greater the installed capacity, the greater the proportion of energy consumption, the more raw materials used and the higher the price.
18,650 lithium-ion battery
Large-capacity, 18650 lithium-ion batteries are generally between Mach 1200 and Mach 3600,lithium battery welding machine while the general battery capacity is only about Mach 800. If the 18650 lithium-ion batteries are combined, the 18650 lithium-ion batteries can easily break through Mach 5000.
2. Long Life: the 18,650 lithium-ion battery has a very long life, with a cycle life of more than 500 times that of an ordinary battery.
3. The safety technical performance is high, and the 18650 lithium-ion power battery has safe production performance and does not explode or burn; Non-toxic and pollution-free, and passed the RoHS trademark product certification; mounting machine The performance of all kinds of information security work has been achieved in one go, and the number of cycles has obviously exceeded 500 times; Good high temperature resistance, 65-degree power management efficiency of 100%.
The high voltage of 18,650 lithium-ion battery is typically 3.6 volts, 3.8 volts and 4.2 volts, much higher than the 1.2 volts of nickel-cadmium and nickel-hydride batteries.
5, no memory effect, no need to empty the remaining power before charging, easy to use.
6. The internal resistance of polymer battery is smaller than that of liquid battery. The internal resistance of domestic polymer batteries can be even less than 35 meters.
The brand of 18650 lithium-ion battery with the same capacity is also a factor affecting the price. Generally speaking, the price of imported brands is higher than that of domestic brands of the same type. As mentioned earlier, an important factor that determines the capacity of 18650 lithium-ion battery is the structure of raw materials. Therefore, from the front, the prices of lithium cobaltate, lithium manganate and ternary materials in lithium ferrous phosphate will be different.
Lithium battery in 18650, inherited the general characteristics of lithium battery, but also has its unique status. First, it is through an important standard battery, making it easy to achieve industrial enterprise production, can be carried out on a large scale to improve the efficiency of social production management, if R & D personnel or custom, at the same time, the 18650 lithium-ion battery features a V-I flame retardant and a sealed multilayer circuit designed to provide effective information to protect the national security of the battery system itself, avoid the dangerous phenomenon of spontaneous combustion or explosion. A balance of nature car or an electric car that uses it as a battery can also greatly protect the safety of passengers or drivers. Finally, the 18650 lithium-ion battery technology research has been relatively mature, if we develop new batteries from the new China or custom-made new batteries, from an economic point of view is not cost-effective. To sum up, 18650 lithium battery is now widely used in China.
