NMC 111 Nickel Manganese Cobalt Oxide (LiNi0.33Mn0.33Co0.33O2) PLD Target

Introduction to NMC 111 Nickel Manganese Cobalt Oxide Thin Film

NMC 111 (Nickel Manganese Cobalt Oxide) is a type of cathode material used in lithium-ion batteries. It is composed of equal parts nickel, manganese, and cobalt oxides, with a chemical formula of LiNi1/3Mn1/3Co1/3O2. NMC 111 is a layered oxide cathode material, meaning that its crystal structure is made up of layers of metal oxide ions. 

NMC 111 is widely used in the field of energy storage, particularly in rechargeable lithium-ion batteries, due to its high energy density, good thermal stability, and low cost. It also has potential applications in other areas, such as catalysts, electrochromic devices, and gas sensors.

 The thin film form of NMC 111 is fabricated using a process called sputtering. There are several methods of thin film deposition, including: physical vapor depsoition (PVD), Plasma laser deposition (PLD), chemical vapor deposition (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.
