The manufacturing technology of lithium batteries is improved every year. Adding new substances to stabilize the chemical process can significantly increase the safety of the use of such products.
Also, modern technologies in the field of production of rechargeable power supplies are aimed at maximizing the power of one element, which positively affects the size and mass of assemblies from such batteries.
Batteries made using LINMC technology have a unique capacity ratio per kg of weight, which is one of the best indicators today. Such products have other positive properties, which will be discussed in detail in this article.

What is Li NMC?
Li NMC batteries are a type of lithium rechargeable battery. The main difference between such products is the use of a complex alloy that contains nickel, manganese and cobalt. A battery anode is made from a mixture of these metals, which can significantly increase the power of the power source.
A feature of the Li-Nickel-Manganese-Cobalt oxide battery is that even at the production stage, you can change the characteristics of the battery by increasing or decreasing the content of the elements that make up the battery.
Specifications and Li NMC device
Given the features of Li NMC, which were given above, the capacity indicators, even with the same size of the battery, can differ significantly. Nevertheless, to get an idea of the characteristics of this battery, it is worth bringing the basic parameters of a battery of this type.
- Voltage: 3.7 V
- Capacity: 3000 mAh or more.
- Number of charge-discharge cycles: at least 1000.
- Thermal breakdown: + 210˚С.
The indicated voltage value is nominal. The maximum battery charge is possible up to a value of 4.3 volts.
Where apply
The main scope of Li NMC batteries is electric transport for various purposes. In this case, the power of the device does not matter. Batteries can be successfully used both in electric scooters and in large machines.
Li NMС batteries are fireproof products, therefore, they can be used as uninterruptible power supplies installed in residential premises.
Such devices are also successfully used in devices where previously installed lithium ion, nickel cadmium and nickel metal hydride power sources.
Advantages and disadvantages
The main advantage of Li NMC batteries is its high electrical capacity. This indicator can reach 220 W * h / kg. Accordingly, in any portable devices, this quality reduces the weight of the batteries.
Electric batteries consisting of Li NMC batteries have high capacitance values. If necessary, you can make an assembly for 10 Ah, 25 Ah and even 60 Ah, while the capacity of one cell can reach 7500 ampere-hours.
If it is necessary to obtain high discharge currents, then Li NMС elements, as a rule, are manufactured with a relatively small capacity (3,000 - 4,000 mAh).
The disadvantages of elements of this type are standard for new technologies. As a rule, the high cost of products does not allow to completely replace obsolete battery models with newer ones. Li NMC batteries made in China can be bought relatively inexpensively, especially if you purchase a bulk batch of goods.
How to charge LINMC batteries
Typically, LINMC batteries are used in assemblies consisting of many cells.If such a battery is installed in an electric car or bicycle, it is enough to connect the network adapter to a special connector of such equipment and charging will occur automatically.
Individual cells can be completely restored by installing them in a lithium battery charger. The full recovery time of LINMC is about 3 hours.
Popular manufacturers and their features
The most popular manufacturer of LINMC batteries is the South Korean company LG Electronics. The batteries produced under this brand are of high quality and long life.
The Chilwee Battery company, which produces reliable LINM cells of standard size, also proved to be quite good. 26650, 32650 and 32700.
What to look for when purchasing
When purchasing new LINMC batteries, the discharge current of the device into which these products will be installed must be taken into account. Under heavy load it is recommended to purchase items with a relatively small capacity.
When buying, you should give preference to sellers who exist in the market for a long time. As a rule, you can find real customer reviews about them who purchased and operate LINMC batteries.
