Enhancing Electrochemical Performance through Li₂Mn₃ZnO₈ Integration into Ti₃C₂Tx MXene Nanocomposites for Advanced Supercapacitors and Hydrogen Evolution Reactions

In this study, we combined Li 2 Mn 3 ZnO 8 with MXene (Ti 3 C 2 T x ) to improve performance in supercapacitors and hydrogen evolution reactions. MXenes are known for their electrical conductivity and high surface area, making them promising for energy storage. The Ti 3 C 2 T x /Li 2 Mn 3 ZnO 8 composite electrode showed a specific capacitance of 182 F g -1 at 1 A g -1 , outperforming individual Li 2 Mn 3 ZnO 8 and MXene electrodes. Even after 3,000 cycles, the composite retained 71% of its initial capacitance. This research introduces innovative electrode materials for next‐generation supercapacitors and hydrogen evolution applications, contributing to sustainable energy solutions.
