Abstract

Lithium ion battery (LiMn2O4) cathode materials have been successfully synthesized using LiCl as a source of Li and MnO2 from waste batteries as a source of Mn. This research aims were to determine the optimum parameters for dry cell paste acid leaching. The parameters that optimized i.e. mass variation of dry cell battery, H2SO4 concentration, and reaction time. The dry cell paste was analyzed using X-Ray Fluorescence (XRF) to determine its composition. The synthesis of LiMn2O4 was carried out by solid state reaction (SSR). MnO2 that obtained from acid leaching was mixed with LiCl with a mole ratio of MnO2 and LiCl (2:1). The mixture then calcined at 750°C for 4 hours followed by sintering at 900°C for 6 hours. LiMn2O4 was characterized by X-Ray Diffraction (XRD). The cyclic voltammetry test on a battery with LiMn2O4 cathode materials obtained shows that the peak pairs of reduction and oxidation were 3.3 V and 4.3 V. The LiMn2O4 charge-discharge test shows that the capacity of the battery were 4.12 mAh/g and 2.12 mAh/g with efficiency of 50.97 %.
