Abstract
work was conducted to study the potential of rice husk silica and lithium battery cathode waste as raw material for making transition metals incorporated in Li2CoSiO4. This study includes the phase analysis, element mapping, band gap energy, and electrical conductivity of the sample. The sample was prepared from fine rice husk silica powder and cathode waste powder with a mass ratio of 1:1 using a solid-state reaction method. It was sintered at 900 oC with a holding time of 12 hours at peak temperature. The results of the phase analysis show that Li2CoSiO4 dominates the phase in the sample, even though there is an impurity phase, i.e., Na2SO4. Elements mapping shows that transition metals in the form of Ni and Mn are incorporated evenly on the surface of the sample. It has band gap energy of around 1.4 eV and electrical conductivity around 6.26x10-5-6.34x10-5 S/m at a range frequency of 1-1000 Hz. In further work, it is essential to study the phase, element mapping, and electrical properties of samples sintered at varying temperatures. Besides, electrochemical performance also needs to be tested.
