| Popis: | Addition of redox active/ inactive dopants often promotes the battery performance of any anode material. In this research work, we report the tin antimony (SnSb) alloy anodes included with three different dopants viz. Cu, Ti and Ce. The relative performances of these three different alloys have been systematically analyzed and reported. The electrochemical studies carried out by cyclic voltammetry analysis exhibit amplified redox activity and better reversibility of doped samples compared to the pristine. The specific capacitance values for 50 cycles are found to be in the range of 34 mAhg−1, 52 mAhg−1, 47 mAhg−1 and 65 mAhg−1 when tested with aqueous LiNO3 electrolyte solution for the pristine, Cu, Ti and Ce doped SnSb alloys respectively. The room temperature AC Impedance analyses of these samples reveal the augmented electrical conductivities of the doped samples. Overall, SnSb: Cu and SnSb: Ce samples are found to offer better anodic properties compared to the other samples. |
