Abstract
In the search for cutting-edge energy storage technologies, alkali ion batteries (AIBs) development has accelerated significantly. Due to its outstanding qualities, indium sulfide (In2S3) has emerged as a potential contender among the many anode materials for lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), and potassium-ion batteries (PIBs). This review paper thoroughly examines In2S3-based materials for AIBs, placing particular emphasis on their importance in the context of environmentally friendly energy storage technologies. We explore In2S3's distinctive characteristics, such as its high theoretical capacity, improved rate capability, cyclability, adjustable bandgap features, and environmental friendliness, which make it suited for AIBs. The development in material engineering, nanostructuring, composite materials, and novel electrode topologies is also highlighted as we discuss current developments in In2S3-based electrodes. In2S3-based materials provide a compelling path towards a cleaner and greener energy future, opening the way for scalable and sustainable energy storage systems thanks to their outstanding features and continuous advances. Further material engineering, improved knowledge of degradation mechanisms, exploring synergistic composite materials, and cutting-edge characterization techniques are all part of the future outlook for In2S3-based materials in AIBs. Due to their large theoretical capacity and advantageous electrochemical characteristics, materials based on In2S3 have demonstrated promise as anodes in AIBs. Researchers can maximize the performance of In2S3 in AIBs by concentrating on these factors, which will progress the development of effective and environmentally friendly energy storage technologies.
