Solid-state batteries use non-flammable solid electrolytes instead of the flammable liquid electrolytes found in lithium-ion batteries, making them safer and less prone to fire. Additionally, they offer the advantage of significantly increasing energy density through efficient cell and system structural design. With the global increase in demand for electrification, an era where everything is powered by batteries is approaching. In response, the Korean government has announced the “National Strategy for Strengthening the Competitiveness of Battery Industry” to support the focused development of national solid-state battery technology. Is Korea developing a Universal standard for Solid-state batteries which needs adoption ?
