Used as a solid lubricant in high-temperature and high-vacuum environments where conventional lubricants fail. Its layered structure allows easy shearing between layers, reducing friction in mechanical systems. Also investigated for use in lithium-ion batteries due to its ability to intercalate lithium ions, enhancing charge storage capacity. Shows promise in catalysis, particularly in hydrogen evolution reactions for water splitting. Applied in composite materials to improve strength and thermal stability. Explored in nanoelectronics and optoelectronics because of its semiconducting properties and potential for flexible, ultra-thin devices.
