Paper Title:
The Effects of Partially Substituting Manganese with Copper in LiMn2O4 Cathodic Material
  Abstract

Although LiMn2O4 is a very promising material for use as cathodes in lithium ion batteries, it exhibits capacity fading on cycling. Substituting some of the Mn with a 3d metal may improve the stability of the material. In this research, LiMn(2-x)CuxO4 (where x = 0.2 and 0.4) are synthesized and characterized by TGA, XRD and EDX. Cyclic voltammetry is also done to study their electrochemical characteristics. Results indicate improved thermal stability and some structural change in the material. Cyclic voltammetry results show the redox potentials have been shifted from those obtained from pure LiMn2O4 material.
