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: Silicon (Si) anodes are expected to be used in lithium-ion batteries (LIBs) in the future due to their high capacity. However, the main challenge is to assemble Si with conductive materials to improve the conductivity and stability of Si anodes. This study optimized a method to prepare Si nanoparticles (NP)/MXene anode materials for LIBs through electrostatic assembly of positively charged Si nanospheres coated with poly-diallyl dimethyl ammonium chloride and negatively charged MXene nanosheets, which increased the active sites for Si NP attachment and reduced restacking of MXene nanosheets and Si NP aggregation. The Si NP/MXene anodes exhibited a capacity of 1917.9 mA h g-1 after 300 charge/discharge cycles at 0.5 A g-1, indicating high energy storage, cycle stability, and rate performance. Optimization of Si/MXene composites can enhance their performance as anode materials for high energy density LIBs.

Summary: CuCo2Se4/reduced graphene oxide (rGO) composites were prepared for the first time by a solvothermal method, and applied as anode material for lithium-ion batteries (LIBs) with excellent performance. CuCo2Se4/rGO showed a reversible capacity of 845.49 mAh g-1 (0.1 A g-1) after 200 cycles, significantly better than CuCo2Se4 (36.90 mAh g-1). The rate performance of CuCo2Se4/rGO (318.4 mAh g-1 at 2 A g-1) was much better than the pure CuCo2Se4 (15.1 mAh g-1 at 2 A g-1). The results indicate a promising future for CuCo2Se4/rGO in LIBs.

Summary: Designing nanocomposites with heterointerface as bifunctional electrocatalysts is a potential strategy to enhance the activity and stability of electrocatalytic water splitting in acidic media. In this study, a highly efficient RuO2/Co3O4 electrocatalyst with a uniform nanoflower structure is prepared by hydrothermal growth combined with interface engineering. The optimized migration of electrons and intermediates, as well as the enhanced electrochemical active surface area at the RuO2/Co3O4 heterointerfaces, contribute to the impressive catalytic activity and stability of the catalyst. RuO2/Co3O4 demonstrates low overpotentials for hydrogen evolution reaction and oxygen evolution reaction, and exhibits a low operating voltage for overall electrochemical water splitting. This study highlights the importance of heterostructure engineering in developing acid-stable bifunctional electrocatalysts for energy conversion applications.
