Abstract

Novel compound comprising of Li2FexMn(1-x)SiO4/MWCNT were prepared by using Sol-Gel technique. In this study, improved electrochemical properties are observed by substituting Fe to replace Mn. and further multiwalled carbon nano tubes are used to prepare composite with prepared cathode material in Lithium ion battery and electrode materials in super capacitors. Various characterization techniques like: FESEM, EDX confirms the structure, morphology and texture of the material. Average particle size is found to be of order of 20-30 nm. As particles with smaller size reveal better electrical conductivity/electrochemical properties, which are confirmed by A.C Impedence spectroscopy and cyclic voltammetery results.
