Synthesis and Characterization of ZnO from Thermal Decomposition of Precipitated Zinc Oxalate Dihydrate as an Anode Material of Li-Ion Batteries

Zinc oxide (ZnO) is one of the most promising materials applied in Li-ion batteries. In this research, ZnO was synthesized by thermal decomposition zinc oxalate dihydrate. This precursor obtained from precipitation process sulfate with oxalic acid. In-depth studies were carried out on effect various heating temperatures dihydrate precursors synthesis. The as-prepared characterized XRD, SEM, and FTIR. Based XRD analysis, presence ZnO-wurtzite phase can be confirmed samples heated at above 400 °C. Meanwhile, SEM-EDX results showed that particles have a micron size. Cells as anodes low columbic efficiency. contrast, cells ZnO/Graphite composite relatively large capacity compared to pure graphite anodes. Overall, based consideration characterization electrochemical performance, optimal sintering temperature obtain 600 °C cell discharge anode form composites 356 mAh/g 450 mAh/g, respectively. suggests used an material additive component improve commercial anodes’ performance.
