“…The electrical conductivity of pure bismuth oxide is 1.550 × 10 −7 Sm −1 [15]. Thus, based on the conductivity values achieved in this study, it can be seen that the addition of activated carbon and graphite with bismuth oxide into a composite product can promote electrical conductivity.…”

“…The monoclinic phase is more favoured as a semiconductor for batteries owing to thermodynamic stability and relatively small band gap [13,14]. However, bismuth oxide does have its shortcomings for such application, which include the low electrical conductivity of its pure form of 1.56 × 10 −7 S•m −1 [15]. This low electrical conductivity, fortunately, may be overcome by combination with a carbon-based composite matrix [16], such as activated carbon and graphite materials, that would help improve the electrochemical performance of Bi-active materials [17].…”

“…The p-Bi 2 O 3 /Ni anode produced had a capacity of 782 mAhg −1 after 40 cycles at a current density of 100 mAg −1 . A more recent research by Astuti et al [15] on the synthesis and characterisation of bismuth oxide-activated carbon composite as battery anode made using the hydrothermal method with variations in weight ratio of activated carbon and bismuth nitrate pentahydrate precursor produced a highest electrical conductivity of 1.24 × 10 −5 Sm −1 from the 1:1 weight ratio variation. Still, its electrical conductivity value was still low and XRD results showed weak peaks.…”

Bismuth oxide/commercial activated carbon/graphite composite was successfully synthesised using the hydrothermal method with time variations and characterisation using Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Scanning Electron Microscopy-Energy Dispersive X-ray mapping, Gas Sorption Analyzer, and battery performance tests including analysis of electrical conductivity, charge–discharge, and cyclic voltammetry. The formation of bismuth oxide is indicated by the presence of Bi-O and Bi-O-Bi groups and the presence of α-Bi2O3 crystal structure. In addition, based on SEM mapping, bismuth oxide particle is well distributed on the composite having rod-like shape morphology. The best electrochemical behaviour is shown by composite synthesised longer that is 1.35 × 10−2 S.m−1, 285.882 mAhg-1, 131.745 mAhg−1 for electrical conductivity, charge specific capacity, and discharge specific capacity, respectively. These results open a way for the composite as Li-ion battery anode.

This research is concerned with the synthesis and characterization of a composite material that may be used as a battery electrode. Bismuth oxide (Bi2O3) was synthesized from Bi(NO3)3·5H2O, Na2SO4, and NaOH mixed with commercial activated carbon and graphite. The composite formation process was carried out using the hydrothermal method at 110 °C for 5 h. The characterization data indicated the composites produced contained Bi2O3 with a monoclinic crystal system, and Bi2O3 particles were evenly distributed in the composite. The composites were characterized to be mesoporous, with the electrical conductivity reaching 10−1 S m−1. The development of this composite material has potential applications in the field of energy storage, particularly in the development of battery anode.

“…Moreover, self standing Bi2O3 nanoparticles/carbon nanofiber hybrid films was succesfully produced as a binder free anode for sodium batteries [5]. Previous research conducted Aprialdi et al [25] on the synthesis and characterization of bismuth oxide/activated carbon composites for battery anodes using the hydrothermal method with variations in the weight ratio of activated carbon to bismuth nitrate pentahydrate at 2: 1, 1: 1, and 1: 2 has resulted in the electrical conductivity of each variation of 0.59 × 10-5 Sm -1 , 1.24 × 10 -5 Sm -1 , and 0.51 × 10 -5 Sm -1 , respectively. However, XRD results showed that bismuth oxide was not fully formed in the composite, and SEM results showed that the distribution of carbon was more dominant than bismuth [25].…”

This study aims to synthesize bismuth oxide/activated carbon composites composed of rice husks for battery anodes and to determine the effect of bismuth nitrate pentahydrate mole variations on the characteristics of the resulting composites. The bismuth oxide/activated carbon composite synthesis was carried out using bismuth nitrate pentahydrate, sodium sulfate, and sodium hydroxide precursors which were mixed with rice husk-based activated carbon. A variation was made for the mole of bismuth nitrate pentahydrate used, while the compositions of activated carbon and other precursors were made fixed. The composites were synthesized using the hydrothermal method at a temperature of 110 0 C for 5 hours. The results showed that bismuth oxide was successfully formed as a composite in the 8 mmol variation with a composite electrical conductivity value of 2.40 x 10 -3 S.m -1 .
