| Abstract |
This research aimed to study the performance of an Al-air battery using three-dimensional carbon nanomaterial architecture from the synthesis of candle flame combustion for using a cathode in a mixed solution of sodium chloride and sodium hydroxide. The results presented that the oxygen reduction reaction (ORR) on the surface of the three-dimensional carbon nanomaterial cathode would increase as the solution contains a proportion of reduced sodium hydroxide, which would make the aluminum battery have a higher capacity density in the mixed solution than in a sodium hydroxide solution, but would still be reduced in sodium chloride. However, the capacity density of the battery does not depend only on the ORR, it also depends on the current density and discharge time interval, which affect the decreasing of the of the aluminum anode and increasing of the capacity density of the mixed solution. The maximum capacity density in the mixed solution was returned as high as 4,688 mAhg-1, which was higher than the sodium chloride and sodium hydroxide solution only for 1.4 times and 12.99 times, respectively. |
