· Li4 V2 B2 O8

Li₄V₂B₂O₈ is an experimental mixed-metal oxide compound containing lithium, vanadium, and boron—a ceramic semiconductor belonging to the family of complex borate-vanadate systems. This research-phase material is being investigated primarily for energy storage and electrochemical applications, where the combination of lithium ion mobility and vanadium's multi-valent redox behavior offers potential advantages over conventional cathode materials. Its viability relative to commercial alternatives (layered oxides, phosphates) depends on synthetic scalability, cycling stability, and rate performance—characteristics still under development in the materials science community.
