Synthesis of activated carbon/bismuth oxide composite and its characterization for battery electrode

Synthesis of activated carbon/bismuth oxide composite and its electrical conductivity characterization have been undertaken. The purpose of this study was to synthesize activated carbon/bismuth oxide composite with several variations in the mass ratio of the composition of both precursors and to characterize the electrical property to determine the potential of this composite material as a battery electrode. Activated carbon from rice husk was mixed with bismuth nitrate pentahydrate with variations in the mass ratio activated carbon and bismuth nitrate pentahydrate 2:1, 1:1, and 1:2. The mixture was then put into a reactor and heated at 100°C for 5 hours. The next step was results of the hydrothermal process were then filtered and dried in an oven. LCR analysis demonstrated that the mass ratio of activated carbon and bismuth oxide 1:1 had the highest electrical conductivity value of 1.24 x 10−5 S.m−1.
