Lithium Manganese Spinel (LiMn2O4) PLD Target

Introduction to Lithium Manganese Spinel (LMO) Thin Film

LMO is a widely used cathode material in lithium-ion batteries due to its high energy density and good cycling performance. There are several techniques for depositing LMO onto substrates, including the Sol-gel method, Electrodeposition, Spray pyrolysis, and Chemical Vapor Deposition (CVD). Lithium Manganese Spinel (LiMn₂O₄) is a popular material used in pulsed laser deposition (PLD) to create thin films for various applications.

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 Manganese Spinel, LMO

Lithium Manganese Spinel is widely used in the production of high-performance cathodes for lithium-ion batteries, and as an electrode material for supercapacitors, due to its excellent electrochemical performance and high stability.

Advantage of Lithium Manganese

Lithium Manganese Spinel exhibits high thermal stability, excellent electrical conductivity, and good cycling stability, making it an ideal material for use in various energy storage applications.

Crystal Structure of Lithium Manganese LiMn2O4

Lithium Manganese has the spinel structure, space group Fd-3m, in which lithium and transition metal atoms occupy the 8a tetrahedral and 16d octahedral sites of the cubic close-packed oxygen ions framework respectively. Lithium can move in 3 dimensions in this structure compared to single plane in layered materials.

Typical substrates for the epitaxial growth of Lithium Manganese Spinel.

Substrates such as MgO, SrTiO₃, and LaAlO₃ are commonly used for the epitaxial growth of Lithium Manganese Spinel, as they have a good lattice match with the crystal structure of LMO.
