Summary: Recent research has shown that not only the solid-electrolyte interphase (SEI) layer but also the metal-ion solvation structure and interfacial model in the electrolyte significantly affect the performance of lithium-ion batteries. In this paper, the authors summarize recent studies on the importance of electrolyte solvation structure, develop a quantitative model, and propose an interfacial model to understand the electrode's performance. These findings may lead to a new era beyond the SEI and have implications for the design and improvement of LIBs.

Summary: This paper examines the behaviors, mechanisms, and influencing factors of Li plating/stripping and proposes general strategies to control Li deposition. It is essential to have comprehensive design strategies for the electrode, electrolyte, and their interface. Three dimensional (3D) anodes and artificial interface engineering can reduce the risk of Li deposition, while electrolyte engineering favors Li transport and suppresses dendrites, serving as the final barrier to uncontrolled Li deposition.

Summary: The large-scale production of stable and active ORR electrocatalysts based on iron was achieved using a core-shell zeolitic imidazolate framework-tannic acid coordination polymer composite (ZIF-8@K-TA) as the catalyst precursor. The resulting H-Fe-Nx-C demonstrated efficient electrocatalytic activity and stability towards the ORR, surpassing the majority of recently reported Fe-N-C catalysts and the standard Pt/C catalyst, with outstanding tolerance to methanol.
