Executive Summary : | This research proposal seeks to identify a cost-effective and environmentally friendly alternative to lithium-ion batteries (LIBs), particularly suitable for use in wearable devices. The proposed alternative is Zinc Ion batteries (ZIBs), which offer a higher theoretical gravimetric capacity of 820 mAh g-1 compared to traditional LIBs. The primary challenge with ZIBs is dendrite formation, leading to short circuits between the anode and cathode and a shortened battery life cycle. To address this issue, the utilization of Vanadium-based Mxene (V2CTx) as the electrode material is proposed. V2CTx exhibits a large surface area, which effectively suppresses dendrite growth and enhances the Zn stripping/plating kinetics, thereby improving ZIBs' performance. The research strategy revolves around synthesizing and optimizing layered V2CTx cathode materials and sulfolane-based aqueous electrolytes. The inclusion of sulfolane-based electrolytes in the system further enhances Zn0 reversibility, suppresses H2 evolution, improves corrosion resistance, and promotes enhanced reaction kinetics and dendrite suppression. The overarching objective of this proposal is to synthesize and fabricate a hybrid AZIBs system that enhances competitiveness within the field of metal-ion batteries. The research will comprehensively investigate the electrochemical behavior of Vanadium Mxene-based AZIBs with sulfolane-based electrolytes under various parameters and conditions. This research encompasses a full research cycle, starting from materials synthesis and physio-chemical characterization, leading to the fabrication of the final hybrid AZIBs device. By addressing the challenges associated with ZIBs and optimizing their performance, this study aims to contribute to the advancement of sustainable and efficient energy storage technologies. |
