国金证券：固态电池产业化节奏逐渐加快 上游相关的核心材料也将从中受益

Core Viewpoint - The core change in solid-state batteries compared to liquid batteries is the use of solid electrolytes instead of liquid electrolytes and separators, which directly impacts key performance indicators such as power density, energy density, and cycle life [1] Summary by Category Solid Electrolyte Types - The most mature industrial applications of solid electrolytes are the sulfide and oxide routes, with sulfide electrolytes having the highest ionic conductivity and the largest capacity layout among downstream companies [1] - Sulfide lithium is a core raw material in the sulfide route, suggesting a focus on companies that are early adopters of sulfide lithium and possess certain technological advantages [1] - Oxide electrolytes have moderate ionic conductivity but better stability, leading to accelerated industrialization progress, indicating a focus on companies that have diversified oxide electrolyte layouts and certain cost advantages in the supply chain [1]
