Summary: In this study, Sb nanoparticles embedded in hollow porous N-doped carbon nanotubes were used as a freestanding anode for Li-ion batteries (LIBs) and K-ion batteries (PIBs). The Sb@N-C nanotubes exhibited exceptional reversible capacity, long cycle stability, and outstanding rate performance in LIBs. The superior electrochemical properties were attributed to the unique structure, allowing for quick ion and electron migration, prevention of particle aggregation, accommodation of volume expansion, and reduction of ion diffusion length.

Summary: Alkaline ion hybrid capacitors, which combine the advantages of batteries and supercapacitors, can bridge the gaps in performance. However, the mismatch in electrochemical kinetics between anodes and cathodes leads to reduced energy density. In this study, a hybrid composite material, CoS/C HC, was synthesized using a cobalt-based metal-organic framework. The material exhibited abundant electrochemical active interfacial sites and good mechanical robustness, making it suitable for use as an electrode material in sodium-ion hybrid capacitors with high energy and power densities.

Summary: The development of sodium hybrid supercapacitors is hindered by the imbalance in reaction rates between the anode and cathode, emphasizing the importance of suitable anode materials for enhanced performance. The sandwich-shell-structured CoMn2O4/C hollow spheres show excellent sodium storage performance with high specific capacity and prolonged cycling durability. A Na-HSC assembled with CoMn2O4/C HSs anode and activated carbon cathode demonstrates high energy density and wide-operating voltage range.

Summary: This study reveals that the mechanism for improving the rate capability of carbonaceous anode through heteroatom doping is not as traditionally believed, which is to increase the diffusion-controlled capacity by expanding the interlayer spacing. Instead, it is found that doping has little impact on interlayer spacing in the bulk phase, but can significantly expand the spacing in the subsurface region when syngergized with tensile stress. This leads to improved accessibility of the subsurface region at high current densities, resulting in higher specific capacity and cycling stability for the electrodes.

Summary: The crystallographic role and electrochemical impact of lithium at different sites in PNNMO were investigated. Lithium occupancy on prismatic Na sites is promoted in Na-deficient PNNMO, leading to enhanced stability and slightly increased specific capacity with partial substitution of Na. However, when lithium is primarily located on octahedral TM sites, capacity is increased at the expense of stability.
