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: Carbon nanosheets (CNSs) with graphite microcrystalline layers and amorphous carbon structures were synthesized using a space-confined carbonization strategy. The microstructures of CNSs were determined by the molecular weight of carbon precursors. Starch-CNSs derived from larger molecular weight exhibited more ordered graphite microcrystalline layers, fewer microporous defects, richer oxygen-containing functional groups, and more mesoporous structures. Starch-CNSs showed excellent lithium storage properties as an anode for lithium-ion batteries.

Summary: In this study, Co0.85Se nanoparticles encapsulated in N-doped carbon matrix nanotubes were successfully prepared using a self-generated sacrificial template method. The stable Co-N/C and Se-C formation, as well as enhanced mechanical strength between active materials and N-doped carbon matrix nanotubes, critically affected the performance by suppressing dissolution of Se/Co, decreasing the energy band, promoting ion/electron movement, and mitigating volume expansion during charge-discharge. The encapsulation of Co0.85Se nanoparticles in a robust carbon matrix inner wall ensured good electron transfer, prevented aggregation of nanoparticles, and provided space for volume changes, ultimately leading to superior electrochemical reversibility.

Summary: By decorating three-dimensional porous Si/SiOx with nitrogen-doped carbon composites through hydrothermal and megnesiothermic reduction, we achieved a high reversible capacity of 1082 mAh g-1 after 200 cycles at a current density of 200 mA g-1. The rate performance of the composites was evaluated from 100 to 1000 mA g-1, and even at a high current density of 1000 mA g-1, the reversible specific capacity remained at 510 mAh g-1. The good electrochemical performance of the composites can be attributed to the three-dimensional porous structure and the introduced nitrogen-doped carbon.

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: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
