NMC 622 Nickel Manganese Cobalt Oxide (LiNi0.6Mn0.2Co0.2O2) PLD Target

Introduction to NMC 622 Nickel Manganese Cobalt Oxide Thin Film

NMC 622 (LiNi0.6Mn0.2Co0.2O2) is a type of lithium-ion battery cathode material that consists of a mixture of nickel, manganese, and cobalt oxides. It belongs to the family of layered oxide cathode materials and is commonly used in high-performance lithium-ion batteries for electric vehicles, consumer electronics, and other applications that require high energy and power densities.

 NMC 622 Nickel Manganese Cobalt Oxide is a popular material used for thin film deposition in various applications, including energy storage, electrochromic devices, and sensors. On this e-commerce website, we provide high-quality targets for pulsed laser deposition of NMC 622 thin films. 

 Thin film is being deposited on SrTiO3 substrates and for electrochemical testing, they can be deposited on SrRuO3 high conducting lattice matched interlayers. Sometimes, Nb-doped SrTiO3 substrates are also used but typically not as easy for electrochemical measurements as SrRuO3 interlayers.

Chemical Composition of NMC 622 Nickel Manganese Cobalt Oxide

The chemical formula of NMC 622 indicates that it contains 60% nickel, 20% manganese, and 20% cobalt. NMC 622 is a ternary oxide with the chemical formula LiNi_0.6Mn_0.2Co_0.2O₂. It consists of nickel, manganese, cobalt, and oxygen.

 In NMC 622  the nickel content is high as compare to cobalt because it was wanted to reduce the amount of Cobalt as it is Toxic and difficult to extract from the ground in a clean way and there is a need for higher voltage cathodes, as the Nickel content increases, so does the voltage. 

Application of NMC 622 Nickel Manganese Cobalt Oxide

NMC 622 thin films have excellent electrochemical properties and are commonly used in lithium-ion batteries as cathode materials. They can also be used in electrochromic devices, such as smart windows and mirrors, and in sensors for gas detection.
