Vanadium dibromide (VBr2) is a layered transition metal halide compound that belongs to the family of two-dimensional materials and van der Waals solids. This is primarily a research-stage material being investigated for its potential in energy storage, catalysis, and electronic applications, rather than an established engineering material with widespread industrial use. The layered crystal structure and moderate mechanical properties make it of particular interest to researchers exploring next-generation battery electrodes, catalytic materials, and thin-film electronic devices.
