Li2 Nb2 Se4

Li₂Nb₂Se₄ is a layered transition metal dichalcogenide semiconductor compound combining lithium, niobium, and selenium in a quasi-2D crystal structure. This is primarily a research material explored for its potential in energy storage, optoelectronics, and quantum applications, rather than a commercially established engineering material. The layered structure and mixed-valence composition make it of interest for battery electrodes, photodetectors, and fundamental studies of charge transport in low-dimensional systems, though engineering-scale applications remain under investigation.
