A composite electrode material was successfully fabricated by a well-designed hydrothermal method supplemented with selenium powder-promoted high-temperature calcined selenization technique, which features Ni3Se4/MoSe2 nanoparticles as charcoal-layer-coated attached and grown on three-dimensional reduced graphene oxide network structure (NMSeCG). The preparation approach ensures the structural stability of composites while bringing into full play synergistic effect among components. results indicate that plentiful diverse heterogeneous interfaces oxide, carbon-layer, Ni3Se4, MoSe2 have potential to enhance active sites effectively regulate electronic structure, resulting in electrochemical reaction kinetics accelerated significantly. anode for lithium-ion batteries such NMSeCG demonstrates exceptional performance lithium storage. Specifically, at 50 mA g–1 current density, initial discharge capacity reaches 822.5 h value, even though density is 40 times increased, it maintains 428.6 capacity. Moreover, after 200 cycles applied 0.5 g–1, cycling remains 106.2%, high value. This study presents practical selenium-based heterostructure materials developed remarkable activity contributes significantly development domain.

Abstract Lithium‐sulfur (Li‐S) batteries, with their high theoretical energy density and cost‐effectiveness, have become one of the most promising next‐generation storage devices. However, they still face challenges such as “shuttle effect” caused by dissolution polysulfide intermediates slow sulfur conversion kinetics. In this study, based on Co 7 Fe 3 alloy catalyst, additional metal is introduced to form a catalyst heterostructure through simple heat treatment process. This incorporated into Ketjenblack (KB) sulfur‐infused cathode material (designated S/KB/Co Co). Li‐S batteries using demonstrate outstanding electrochemical performance, maintaining reversible specific capacity over 500 mAh g −1 after 1000 cycles at current 1 C, decay rate 0.046% per cycle. DFT calculations experimental results both reveal that introduction effectively regulates d‐band center material, enhancing adsorption promoting bidirectional catalytic conversion. work highlights importance construction heterostructured materials role in improving performance batteries.
