The price of 18650 lithium-ion power battery, the capacity of the battery is getting larger and more expensive?


The 18650 lithium-ion battery can be divided into capacity type and multi-duty. 18650 pack builder The capacity type is important for large capacities, but the discharge current is usually less than 1C and the current is small. The price of the 18650 lithium-ion battery is proportional to the capacity. The larger the installed capacity, the larger the energy consumption ratio, the more raw materials used, the higher the price.

The advantages of 18650 lithium-ion batteries

Large capacity, 18650 lithium-ion batteries are generally between Mach 1200 and 3600, battery manufacturing machine while the general battery capacity is only about Mach 800, if the 18650 lithium-ion batteries combined, 18650 lithium-ion batteries can easily break through Mach 5000.

Long service life: The service life of 18650 lithium-ion battery is very long, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.

high safety technical performance, 18650 lithium-ion power battery for safe production performance, li ion battery construction no explosion, no combustion; Non-toxic, pollution-free, through the RoHS trademark product certification; All kinds of information security work performance in one go, the number of cycles is significantly more than 500 times; Good high temperature resistance, 65 degrees of power management efficiency of 100%.

The voltages of high-voltage 18650 Li-ion batteries are typically 3.6 volts, 3.8 volts, and 4.2 volts, which is much higher than the 1.2 volts of nickel-cadmium batteries and nickel-metal hydride batteries.

no memory effect, no need to empty the remaining power before charging, easy to use.

The internal resistance of polymer batteries is less than that of liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35 meters.

The brand of the 18650 lithium-ion cell 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 in determining the capacity of the 18650 lithium-ion battery is the structure of the raw material. Therefore, from the positive point of view, the price of lithium cobaltate, lithium manganate and ternary materials in lithium ferrous phosphate will be different.

18650 lithium battery, inherited the general characteristics of lithium battery, but also has its unique place. First of all, it is through an important standard battery, so that it is easy to achieve industrial enterprise production, can carry out large-scale improvement of social production management efficiency, if the R & D personnel or customized, the efficiency problem will start to drop to a lot; At the same time, the 18650 lithium battery has the characteristics of V-I flame retardant and closed multi-layer circuit design protection, which can obtain effective information to protect the national security of the battery system itself and avoid the phenomenon of spontaneous combustion or explosion at risk. Using it as the battery of an ecological balance car or an electric vehicle can also greatly protect the safety of riders or drivers. Finally, the process research of 18650 lithium batteries has become relatively mature, if we develop new batteries or customized new batteries from the new China, it is not cost-effective from the perspective of economic environment. Considering the above, 18650 lithium battery is currently widely used in China.
