Summary: Heteroatom doping is a common modification method for lithium-ion battery electrodes, and it can improve the electrochemical performance of materials. In this study, CO2-modified VO2(B) nanorods were synthesized, resulting in a CO2-VO2 electrode with high rate capacity and capacity retention. The role of CO2 small molecules as a pillar in the interlayer of VO2(B) and the weak electrostatic attraction between OCO2 and Li+ contribute to the stability and diffusion of lithium ions.

Summary: A carbon-decorated MoS2/CoS heterostructure was synthesized to enhance the performance of sodium-ion batteries. The built-in electric field at the MoS2 and CoS heterointerfaces improved the electron conductivity and Na-ion transport rate. The different redox potentials between MoS2 and CoS effectively mitigated mechanical strain and maintained structural integrity. The resulting MoS2/CoS@CC electrode exhibited high reversible capacity and excellent rate performance.

Summary: A spherical composite of silicon oxycarbonitride with ultrafine CoS (CoS@SiOCN) is synthesized as an anode material for lithium-ion batteries. The in-situ formation of well-dispersed CoS particles is achieved through the pyrolysis of a polymerized product of Co(II) with a Schiff-base ligand. Compared to other anodes, the CoS@SiOCN anode exhibits superior cyclic performance and a high initial reversible capacity, attributed to its unique structure and well-dispersed CoS particles. The electrochemical analysis indicates that both CoS and in-situ formed Co nanoparticles contribute to the electrochemical properties.

Summary: A novel structural Si-based anode with high compact density, stability, and superior performance during cycling is proposed in this study. The method involves adding a small amount of Sn to the Si anode material, carbonization of the organic binder, subsequent hot pressing, and the formation of a Cu3Si/Cu3Sn interlayer, leading to metallurgical bonding between the active materials and the current collector. The electrode shows potential for high volumetric capacity and offers new insights into advanced silicon-based anodes for lithium-ion batteries.

Summary: FeS2/CoS and FeS2/CoS/C composites were synthesized via solvothermal method and vapor phase vulcanization, using CoFe2O4 as precursors. The composites exhibited similar morphology of solid microspheres. As anode materials for LIBs, the composites showed higher reversible capacity and better cycling performance compared with bare FeS2 and CoS. The FeS2/CoS composite with a molar ratio of Fe3+ and Co2+ of 2:1 achieved a high reversible capacity of 1150 mAh g(-1) after 100 cycles at 100 mA g(-1) and even 610 mAh g(-1) at 1.0 A g(-1) after 900 cycles. This strategy of synthesizing heterogeneous binary sulfides can effectively improve the kinetics and enhance the electrochemical performance of materials. This work provides an effective method and idea for the preparation and modification of FeS2 and other transition metal sulfide anode materials for LIBs in the future.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
