The Pursuit for High Power Density in Silicon‐Based ASSBs: Insights Into Limitations and Perspectives (Adv. Energy Mater. 14/2026)

All-Solid-State Batteries In article number e05061, Jaekyung Sung and co-workers illustrate the role of integrated design in mitigating mechanical degradation and interfacial instability. Compared to conventional electrodes with cracks, voids, and side reactions, the optimized structure maintains electrical contact, alleviates stress, and minimizes parasitic reactions, thereby improving rate capability at high current and low stack pressure operations.
