Summary: A freestanding membrane with a unique bean pod-like structure composed of nitrogen-doped carbon fibers and hollow carbon spheres encapsulated with SnCo nanoparticles was synthesized. The Sn acts as a host for Na+ storage, while the Co serves as an electrochemically inactive matrix that buffers volume variations and inhibits aggregation and particle growth of the Sn phase. The introduction of hollow carbon spheres provides sufficient void space to withstand volume expansion and improves anode conductivity. The freestanding membrane also increases the contact area between the active material and the electrolyte, providing more active sites during cycling. When used as an anode material for Na-ion batteries, the B-SnCo/NCF anode exhibits excellent rate capacity and specific capacity.

Summary: Employing lithium-rich layered oxide (LLO) as the cathode in all-solid-state batteries (ASSBs) is desired for high energy density, but its poor kinetics due to low electronic conductivity and oxygen-redox-induced structural degradation hinders its application. This study enhances the charge transfer kinetics of LLO by constructing efficient electron transport networks within solid-state electrodes, reducing electron transfer resistance, and stabilizes the lattice oxygen of LLO through an infusion-plus-coating strategy, suppressing interfacial oxidation and structural degradation. The LLO-based ASSBs exhibit high discharge capacity and long cycle stability, providing important insights for the development of high-energy-density ASSBs.

Summary: In this study, the addition of CMC electrolyte additive in AZICs successfully addresses the performance issues caused by zinc deposition and parasitic reactions. The CMC additive can adsorb onto the (101) facet of zinc, preventing the formation of zinc dendrites. Moreover, the interaction of CMC with Zn2+ alters the solvation structure and suppresses water-induced side reactions. This strategy significantly improves the cyclic stability of the zinc anode at both low and high rates, thus promoting the comprehensive performance of AZICs.
