“The shift toward all-solid-state battery architectures represents the biggest materials science challenge since lithium-ion commercialization. While current 20-layer prototypes achieve 420Wh/kg, scaling to automotive-grade 800-layer systems requires solving interfacial resistance issues through atomic-layer deposition techniques. Expect 2028 production models to feature hybrid solid-liquid electrolyte systems as a transitional technology.”Dr. Elena Varela, Battery Innovation Consortium CTO
