Lithium Nickelate (LNO) LiNiO2 PLD Target

Lithium Nickelate (LNO) or LiNiO2 is a high voltage layered cathode material used in lithium-ion batteries. It is one of the promising materials for next-generation batteries due to its high energy density and low cost. 

Lithium Nickelate is a transition metal oxide with a perovskite crystal structure. It is widely used in thin film form due to its unique properties such as high electrical conductivity, excellent electrochemical stability, and strong magnetism.

The most common method for depositing LiNiO2 thin films is by physical vapor deposition (PVD) techniques such as sputtering or pulsed laser deposition (PLD).Lithium Nickelate thin films have been extensively studied for their potential applications in energy storage devices, spintronics, and catalysis.

 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.

Application of Lithium Nickelate

Lithium Nickelate thin films have various applications in the field of electronics and energy storage. They are used in the production of batteries, supercapacitors, and fuel cells. Lithium Nickelate is also used in spintronic devices, which have potential applications in magnetic data storage and spin-based computing.
