A sulfur host based on titanium monoxide@carbon hollow spheres for advanced lithium–sulfur batteries
Lithium-sulfur batteries show advantages for next-generation electrical energy storage due to their high energy density and cost effectiveness. Enhancing the conductivity of the sulfur cathode and moderating the dissolution of lithium polysulfides are two key factors for the success of lithium-sulfur batteries. Here we report a sulfur host that overcomes both obstacles at once. With inherent me...
متن کاملAssembled hollow and core-shell SnO2 microspheres as anode materials for Li-ion batteries
SnO2 microspheres with controllable morphology were prepared via a hydrothermal-annealing method. The SnO2 morphology can be tuned by using AlOOH sol and g-Al2O3 as additive. The hollow SnO2 microspheres with incomplete core-shell structure prepared with small amount of g-Al2O3 presented the best cycling performance in Li-ion battery, exhibiting a specific capacity of 374.2 mAh g 1 up to 100 cy...
متن کاملHollow carbon nanospheres/silicon/alumina core-shell film as an anode for lithium-ion batteries
Hollow carbon nanospheres/silicon/alumina (CNS/Si/Al₂O₃) core-shell films obtained by the deposition of Si and Al₂O₃ on hollow CNS interconnected films are used as the anode materials for lithium-ion batteries. The hollow CNS film acts as a three dimensional conductive substrate and provides void space for silicon volume expansion during electrochemical cycling. The Al2O3 thin layer is benefici...
متن کاملMesoporous hollow carbon spheres for lithium–sulfur batteries: distribution of sulfur and electrochemical performance
Hollow carbon spheres (HCS) with a nanoporous shell are promising for the use in lithium-sulfur batteries because of the large internal void offering space for sulfur and polysulfide storage and confinement. However, there is an ongoing discussion whether the cavity is accessible for sulfur. Yet no valid proof of cavity filling has been presented, mostly due to application of unsuitable high-va...
متن کاملHierarchical TiO2 spheres as highly efficient polysulfide host for lithium-sulfur batteries
Hierarchical TiO2 micron spheres assembled by nano-plates were prepared through a facile hydrothermal route. Chemical tuning of the TiO2 through hydrogen reduction (H-TiO2) is shown to increase oxygen-vacancy density and thereby modifies the electronic properties. H-TiO2 spheres with a polar surface serve as the surface-bound intermediates for strong polysulfides binding. Under the restricting ...
