| Popis: | We have developed novel cathode materials in the chemical composition of Li2ZnSiO4, Li1.5Zn1.5SiO4, Li1Zn2Sio4, Li0.5Zn2.5SiO4 and Zn2SiO4 by a sol-gel method. Structural and thermal properties of these materials have been carried out from the measurement of their XRD, FTIR, and TG-DTA profiles. For the Zn2SiO4 sample, the optimized synthesis temperature has been found to be 900°C and maintaining this temperature; the remaining other samples have also been developed for their analysis. The ac conductivity, dielectric constant, dielectric loss values have been obtained and their trends have been explained on the basis of the distribution of Li+ ions in them because of their display of Maxwell- Wagner interfacial- type polarization. |
