Advanced Science, EarlyView.In this study, we developed elastic hollow graphene spheres (GS) that serve as a pore‐engineering additive. This strategy enables the direct fabrication of porous electrodes, effectively mitigating volume expansion and mechanical stress in silicon‐based anodes during cycling without compromising active material or increasing production costs.

Hydrogen Production from Ammonia Electrochemical Cracking
Advanced Science, EarlyView.NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries
Advanced Energy Materials, EarlyView.The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries
Advanced Energy Materials, EarlyView.This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,
