High-Energy-Density Quasi-Solid-State Supercapacitor with a MoS2@FeS2 Core–Shell Heterostructure as an Advance Electrode Material

“…The urgency arises due to the rapid depletion of fossil fuels and modern industrialization, which directly impacts the global climate. − In recent decades, supercapacitors have attracted tremendous attention due to their unique charge storage mechanisms and efficiency. Supercapacitors stand out not only for their exceptional energy storage capabilities but also for their prolonged operational lifespan, maintaining an efficiency of approximately 90% even after 10 000 charge–discharge cycles, making them a long-term champion compared to typical batteries. − Nowadays, transition metal sulfides (TMSs) are emerging materials with unique structures, high theoretical capacitance, abundant active sites, excellent electrochemical properties, natural abundance, and cost-effectiveness, making them promising electrode materials for energy storage applications. − The remarkable capacitance exhibited by TMSs can be attributed to their ability to undergo rapid redox reactions, facilitating the efficient transfer of a considerably greater number of electrons. These advantages arise due to the low electronegativity of the sulfur atom and a narrow energy band gap, which provides smoother electron transport, high conductivity, and a more stable configuration.…”

Phase-Engineered Tin Sulfides and Their Heterostructure with Ti3C2Tx MXene for All-Solid-State Flexible Asymmetric Supercapacitors

“…In the symphony of our ever-expanding global population and the relentless consumption of fossil fuels, an unyielding energy crisis has taken center stage .
