C-1: Preparation of Battery-grade Ferrous Oxalate by Screening of Reaction Conditions: Keyu Zhang1; Xiaoyan Yang1; Jian Wu1; Yaochun Yao1; 1Kunming University of Science and Technology
     Ferrous oxalate, a kind of chemical material, is widely used as chemical precursors of synthetic nanomaterials, ceramic superconductors or catalysts. In this study, battery-grade ferrous oxalate was prepared by using liquid-phase precipitation method for raw material of lithium-ion battery. Various factors such as the concentration of ferrous sulfate and oxalic acid solution, reaction temperature, pH values, stirring speed and dispersant proportion were investigated to prepare high-performance ferrous oxalate by Plackett-Burman design (PBD). Results revealed that the model owned a good fitted response and a good liner correlation with the date of Adj R-Squire, C.V, and Adeq Precision. The reaction temperature, pH values, concentration of ferrous sulfate and aging time had significant effects on the particle size of ferrous oxalate. The concentration of ferrous sulfate had substantial negative effects on particle size and the purity of ferrous oxalate.

C-2: Synthesis and Characterization of Electrodes Made from Banana Peel for Multivalent Batteries: Tazmin Mumu1; Ramesh K. Guduru1; 1Lamar University
    Currently growing demand for high energy density and safer batteries have led researchers to explore for new alternatives to Li-ion batteries, especially multivalent ion batteries. Among various multivalent chemistries, Al has attracted more attention because of more charge, less expensive and safer compared to the Li-ion batteries. Therefore, in this research, we explored the applicability of carbon electrodes made of banana peel in Al-ion batteries. Initially, banana peel were thermally treated at 900 0C in Argon atmosphere to obtain carbon, and then washed with chemicals and de-ionized water to remove unwanted residue. Thus obtained carbon was also verified for purity through thermo gravimetric analysis, and then characterized for phase, microstructures and electrochemical properties for Al-ion battery applications, which will be presented in the conference. These studies demonstrate the use of banana peel in rechargeable batteries as an attractive solution from the waste recycling point of view.
