C @ S nanocomposites based on mesoporous hollow carbon capsules, a restricted polysulfide shuttling and an improved electron transport on sulfur are attributed to their excellent properties as a cathode material in a lithium secondary battery of S-sequestration of elemental sulfur.
Hollow Micro‐/Nanostructures: Synthesis and Applications
Hollow micro‐/nanostructures are of great interest in many current and emerging areas of technology. Perhaps the best‐known example of the former is the use of fly‐ash hollow particles generated from…
Poly(ethylene oxide)/Silica Nanocomposites: Structure and Rheology
The effects of polymer−particle and particle−particle interactions on viscoelastic properties of nanocomposite materials are investigated using narrow molecular weight distribution poly(ethylene…

Solid-state electrolytes (SSEs) have emerged as high-priority materials for safe, energy-dense and reversible storage of electrochemical energy in batteries. In this Review, we assess recent progress…
Stable lithium electrodeposition in liquid and nanoporous solid electrolytes.
This work finds that simple liquid electrolytes reinforced with halogenated salt blends exhibit stable long-term cycling at room temperature, often with no signs of deposition instabilities over hundreds of cycles of charge and discharge and thousands of operating hours.
Template‐Free Synthesis of SnO2 Hollow Nanostructures with High Lithium Storage Capacity
Constructing hierarchical spheres from large ultrathin anatase TiO2 nanosheets with nearly 100% exposed (001) facets for fast reversible lithium storage.
This work shows that the high surface density of exposed TiO(2) (001) facets leads to fast lithium insertion/deinsertion processes in batteries that mimic features seen in high-power electrochemical capacitors.
