Numerous efforts are made to improve the reversible capacity and long‐term cycling stability of Li‐S cathodes. However, they are susceptible to irreversible capacity loss during cycling owing to shuttling effects and poor Li+ transport under high sulfur loading. Herein, a physically and chemically enhanced lithium sulfur cathode is proposed to address these challenges. Additive manufacturing is used to construct numerous microchannels within high sulfur loading cathodes, which enables desirable deposition mechanisms of lithium polysulfides and improves Li+ and e‐ transport. Concurrently, cobalt sulfide is incorporated into the cathode composition and demonstrates strong adsorption behavior toward lithium polysulfides during cycling. As a result, excellent electrochemical performance is obtained by the design of a physically and chemically enhanced lithium sulfur cathode. The reported electrode, with a sulfur loading of 8 mg cm‐2, delivers an initial capacity of 1118.8 mA h g‐1 and a reversible capacity of 771.7 mA h g‐1 after 150 cycles at a current density of 3 mA cm‐2. This work demonstrates that a chemically enhanced sulfur cathode, manufactured through additive manufacturing, is a viable pathway to achieve high‐performance Li‐S batteries. [ABSTRACT FROM AUTHOR]

The hierarchical V 2 O 5 nanofibers cathode materials with diameter of 200–400 nm are successfully synthesized via an electrospinning followed by annealing. Powder X-ray diffraction (XRD) pattern confirms the formation of phase-pure product. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) obviously display the hierarchical porous nanofibers constructed by attached tiny vanadium oxide nanoplates. Electrochemical behavior of the as-prepared product is systematically studied using galvanostatic charge/discharge testing, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). It turns out that in comparison to the commercial V 2 O 5 and other unique nanostructured materials in the literature, our V 2 O 5 nanofibers show much enhanced lithium storage capacity, improved cyclic stability, and higher rate capability. After 100 cycles at a current density of 800 mA g −1 , the specific capacity of the V 2 O 5 nanofibers retain 133.9 mAh g −1 , corresponding to high capacity retention of 96.05%. More importantly, the EIS at various discharge depths clearly reveal the kinetics process of the V 2 O 5 cathode reaction with lithium. Based on our results, the possible approach to improve the specific capacity and rate capability of the V 2 O 5 cathode material is proposed. It is expected that this study could accelerate the development of V 2 O 5 cathode in rechargeable lithium ion batteries. [ABSTRACT FROM AUTHOR]
