Abstract Advanced battery systems based on solid electrolytes promise superior energy storage performance and better security than current liquid electrolytes‐based Li‐ion batteries (LiBs). Li‐metal anode solid‐state (SSBs) have been extensively studied, but chemically active Li seems to be incompatible with SSB featuring high safety stability. This contradiction runs through the whole process of electrode fabrication, cell stacking, operation. Poor chemical stability in air results manufacturing costs, dendritic formation, uncontrolled interfacial reactions, increasing risk thermal runaway. Silicon anodes, characterized by capacity, low working potential, mild properties, abundant natural resources, successfully applied commercial systems. Research Si anodes‐based SSBs (Si‐SSBs) is great significance given that rapid development field has put forward higher demands for density safety. However, publications comprehensively summarize studies Si‐SSBs, from fundamentals practical applications are scarce. Therefore, this review intended provide a comprehensive overview research, involving material, electrode, cell, package then propose prospects future direction scientific research industrial SSBs.
