NMC 811 Nickel Manganese Cobalt Oxide (LiNi0.8Mn0.1Co0.1O2) PLD Target

Introduction to NMC 811 Nickel Manganese Cobalt Oxide Thin Film

NMC 811 is called 811 because it has a composition of 80% nickel, 10% manganese, and 10% cobalt. NMC 811 is a type of cathode material used in lithium-ion batteries. It is a layered oxide material made of nickel, manganese, and cobalt in the ratio of LiNi0.8Mn0.1Co0.1O2. The numbers in the formula refer to the relative percentages of the metals in the material.

NMC 811 Nickel Manganese Cobalt Oxide is a thin film material used in pulsed laser deposition. This material has a unique chemical composition and crystal structure, which make it ideal for various applications in thin film form. There are several methods of this thin film deposition, including: Pulse laser depsoition (PLD), physical vapor depsoition (PVD), chemical vapor deposition (CVD), CVD, and sol-gel method. 

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 811 Nickel Manganese Cobalt Oxide

NMC 811 Nickel Manganese Cobalt Oxide is a ternary oxide. It is made up of nickel, manganese, and cobalt in a specific ratio, with the formula LiNi0.8Mn0.1Co0.1O2 indicating that the material contains 80% nickel, 10% manganese, and 10% cobalt. 

In NMC 811 the Nickle content is kept high as compare to cobalt because there is a want 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.
