Abstract : With the advancement of nanotechnology, there is an interest in the replacement of conventional materials by nanomaterials. There is a reasonable chance that as the active mass of electrode for lithium batteries is comprised of smaller particles, they will perform better in terms of capacity, power, rate capability and stability. LiMn2O4 is inexpensive material but it shows rather poor cyclic performance. The electrochemical performance of spinel type LiMn2O4 has been effectively improved with doping of Nd the
