Nickel or Ni is used widely in batteries. The significance of using nickel in batteries is that it helps in delivering high energy density and more excellent capacity storage at a little cost. This results in making the cost of each kWh of battery storage much competitive.
The lithium ion batteries were incorporated and used into the next generation of electric vehicles, i.e., cars. Their higher power density has become crucial for moving vehicles for long distances. Lithium ion batteries containing nickel is commonly used in car batteries in order to offer excellent energy density and lower cost of storage.
There are majorly two categories of batteries, i.e., primary and secondary. The primary batteries are used for once because they are disposable. But secondary batteries are rechargeable batteries that can be reused. There is a wide number of secondary batteries which are available in the market. For example, nickel cadmium (NiCd), lead acid battery, nickel metal hydride (NiMH), and lithium ion batteries. Nickel is a vital component for the cathodes of secondary battery designs, including lithium ion batteries.
The difference between nickel manganese cobalt and lithium ion batteries can be clearly determined with the following detailed discussion.
" Nickel manganese cobalt batteries
This is one of the most famous lithium ion systems which have a cathode combination of nickel-manganese-cobalt. This system can be used to operate as power cells or energy cells. The components of NMC are combined and made with nickel and manganese. Nickel is popular for its high energy density but low and poor stability. Whereas, manganese has the merit of forming a spinel structure to gain low internal resistance but provides low specific energy. When these two metals are combined together, they enhance each other strengths very well.
Nickel manganese cobalt batteries are an excellent choice for e-bikes, power tools, and other electronic power trains. The cathode combination consists of one third of nickel, one third cobalt, and one third of manganese. The ratio stands as 1:1:1, which offers a unique mix and blend; it also lowers the cost of raw material due to the low amount of cobalt content. The nickel based batteries systems have a high energy density, low cost, and long life span as compared to the cobalt based cells, but they possess slightly low voltage output. Nickel manganese cobalt batteries serve as a hybrid cell as well, whose market share is increasing.
" Lithium ion battery
The lithium batteries started beginning to produce in 1912 by G.N Lewis. Lithium is the lightest among all the metals. It offers great electrochemical potential and enormous energy density. Many attempts got failed to manufacture rechargeable lithium batteries because it had some safety issues. Lithium ion batteries that are rechargeable are a safe option provided that certain precautions are taken into consideration when the battery is put to charge and discharge.
There is a thing to notice in lithium ion batteries, which are the energy density of lithium ion batteries is twice than the standards of nickel cadmium batteries. The lithium ion batteries have similar characteristics in terms of discharge. The high cell voltage of 3.6 volts allows battery pack designs with only one cell, whereas the nickel based batteries require three 1.2 volt cells.
Aging is one of the issues with most lithium ion batteries. The deterioration of capacity is noticeable after around one year. The battery fails to perform after two or three years. The producers are trying to improve lithium batteries continually. There are new and enhanced chemical combinations in every six months.
Can you replace lithium ion with nickel manganese cobalt battery?
Lithium is expensive because the resources are irregular distribution across the planet. Gallons of drinking water are used in the extraction of lithium. Also, the extraction techniques are becoming more costly and energy intensive due to the rising demand for lithium. With the continually growing demands of electric power trains, electric cars, and electronic bikes, the requirement of rechargeable batteries is increasing drastically. Therefore, it would be best to discover something that carries similar features to lithium ion batteries, which does not cost much and is available.
The nickel manganese cobalt batteries can prove to be a great replacement because, as mentioned earlier, nickel based batteries have high density and low cost. It is true that lithium ion batteries cannot be replaced entirely because they carry low maintenance costs. They have relatively low self discharge; the self discharge rate of lithium ion batteries is low than that of the nickel based batteries. Therefore it is a bit hard to say that lithium ion can be replaced on the whole with nickel manganese cobalt batteries.
Well, that's all for nickel manganese cobalt batteries and lithium ion batteries. With the above listed difference, you can easily make out which battery will work best for your purpose.
