LiAlSe2 is a ternary lithium aluminum selenide compound belonging to the chalcogenide family of materials. This compound is primarily of research and development interest rather than an established commercial material, with potential applications in optoelectronics and solid-state ion conductors where lithium-containing ceramics are explored. Its significance lies in the material family's potential for optical transparency in the infrared spectrum and possible use in advanced energy storage or photonic devices, though practical industrial adoption remains limited.
