LG Energy Solution identifies the primary hurdle for solid-state batteries as scaling large-cell production, predicting the technology will appear in smartphones roughly ten years before it becomes viable for electric vehicles. Europe’s first solid-state gigafactory began construction in France in February, while the newly opened U.S. battery plant remains skeptical about near-term solid-state cell deployment.
