South Korea’s Standard Energy has unveiled a vanadium‑ion battery designed for grid and energy‑storage applications.

South Korea’s Standard Energy has developed a vanadium-ion battery that retains ~99% capacity after 20,000 deep‑discharge cycles—just 1% degradation—with a round-trip efficiency of 96%, using safe, non‑flammable aqueous electrolytes. They’ve already deployed 10 MWh domestically as they aim to expand into Japan and Europe.

Standard Energy, the world's first developer of the Vanadium Ion Battery (VIB), has made its first major step toward entering the North American market by successfully participating in CES 2025 held last week in Las Vegas, Nevada.
