Fabrication Of Lithium-Carbon Composite Material From Pepper Peel Waste As Battery Electrodes
Abstract The manufacture of battery cathode electrodes made of LiFeO4 and activated carbon from pepper peel has been successfully carried out. The electrodes were made using the soli state reaction method with the addition of adhesives in the form of PVdf and NMP. The resulting homogeneous mixture is then placed in a mold and dried in an oven at 90° to dry to form sheets. The dried electrode sheets were then characterized using FTIR and tested for conductivity values using EIS. The FTIR results showed that there was no change in the functional group with the addition of carbon mass. Meanwhile, the results of the conductivity test showed that the optimum conductivity value occurred in the sample with the addition of 10% carbon mass is 7.42 × 10-4 S/cm.
