Development of Novel Cathode Materials based on MWCNT for Energy Storage/Conversion Devices
摘要：
采用溶胶-凝胶法制备了Li 2FexMn（1-x）SiO 4/MWCNT复合材料。在这项研究中，观察到改善的电化学性能，通过取代Fe取代Mn。进一步将多壁碳纳米管与制备的锂离子电池正极材料和超级电容器电极材料制备复合材料。各种表征技术，如：FESEM，EDX证实了材料的结构，形态和纹理。发现平均粒度为20-30 nm的量级。随着颗粒尺寸的减小，显示出更好的导电性/电化学性能，这被交流阻抗谱和循环伏安法结果所证实。
英文摘要：
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.
