Abstract
Material katoda baterai ion lithium (LiMn2O4) telah disintesis dengan prekusor LiCl sebagai sumber Li dan MnO2 dari limbah baterai dry cell sebagai sumber Mn. Penelitian ini bertujuan untuk mengetahui kondisi optimum pelindian limbah baterai dry cell yaitu meliputi massa serbuk baterai dry cell, konsentrasi H2SO4, dan waktu untuk memurnikan MnO2 pada limbah baterai dry cell dan MnO2 yang dihasilkan dari pelindian tersebut akan digunakan sebagai material untuk membuat katoda baterai ion lithium yaitu LiMn2O4. Limbah baterai dry cell diuji X-Ray Fluorescence (XRF) untuk mengetahui komposisi unsur dalam bentuk oksida. Metode yang digunakan pada sintesis LiMn2O4 adalah Solid State Reaction (SSR). MnO2 dicampurkan dan dihomogenkan dengan LiCl dengan perbandingan mol MnO2 dan LiCl (2:1). MnO2 dan LiCl kemudian dikalsinasi pada suhu 750°C selama 4 jam dilanjutkan sintering pada suhu 900°C selama 6 jam. LiMn2O4 dikarakterisasi X-Ray Diffraction (XRD) dan elektrokimia. Uji cyclic voltamettry pada baterai dengan katoda LiMn2O4 menunjukkan pasangan puncak oksidasi reduksi berada diantara tegangan 3,3 V hingga 4,3 V. Hasil uji charge-discharge LiMn2O4 4,12 mAh/g dan 2,12 mAh/g dengan efisiensi 50,97%.

Lithium ion battery cathode material (LiMn2O4) has been synthesized with precursor LiCl as a source of Li and MnO2 from dry cell battery waste as a source of Mn. This study aims to determine the optimum conditions for leaching dry cell batteries, which include the mass of dry cell battery, H2SO4 concentration, and the time to purify MnO2 in dry cell and MnO2 battery waste generated from leaching to be used as a material for cathode lithium ion batteries LiMn2O4. The dry cell battery waste was tested by X-Ray Fluorescence (XRF) to determine the elemental composition in the form of oxide. The method used in the synthesis of LiMn2O4 is the Solid State Reaction (SSR). MnO2 is mixed and homogenized with LiCl with a mole ratio of MnO2 and LiCl (2: 1). MnO2 and LiCl were then calcinated up at 750 ° C for 4 hours followed by sintering at 900 ° C for 6 hours. LiMn2O4 was characterized by X-Ray Diffraction (XRD) and electrochemistry. The cyclic voltamettry test on batteries with the LiMn2O4 cathode shows that the reduction oxidation peak pair is between 3.3 V to 4.3 V. The LiMn2O4 charge-discharge test results are 4.12 mAh / g and 2.12 mAh / g with efficiency of 50.97%.
