Constructing MIL-101(Cr) membranes on carbon nanotube films as ion-selective interlayers for lithium–sulfur batteries
It is of significant importance to suppress the polysulfide shuttle effect for the commercial application of lithium–sulfur batteries. Herein, continuous MIL-101(Cr) membranes were successfully
Lithium–Metal Batteries Using Sustainable Electrolyte Media and Various Cathode Chemistries
The use of concentrated glyme-based electrolytes, the fine-tuning of the operative conditions, and the careful selection of active materials chemistry are suggested as significant steps to achieve practical and safe lithium–metal batteries.
A Stable High‐Capacity Lithium‐Ion Battery Using a Biomass‐Derived Sulfur‐Carbon Cathode and Lithiated Silicon Anode
The data reported herein well indicate the reliability of energy storage devices with extended cycle life employing high-energy, green and safe electrode materials.
Simple and Sustainable Preparation of Cathodes for Li−S Batteries: Regeneration of Granular Activated Carbon from the Odor Control System of a Wastewater Treatment Plant
This “trash into treasure” strategy leads to a new way for using hazardous waste material as high‐performance and environmentally safe electrodes for advanced Li−S batteries.

Highly graphitized carbon nanosheets with embedded Ni nanocrystals as anode for Li-ion batteries
A C/Ni composite was prepared via thermal decomposition of a nickel oleate complex at 700 °C, yielding disperse Ni nanocrystals with an average size of 20 nm, encapsulated by carbon nanosheets as
Cr2O3/carbon nanosheet composite with enhanced performance for lithium ion batteries
A Cr2O3/carbon nanosheet composite is directly synthesized by solution combustion synthesis using chromium nitrate as the chromium source and glucose as the carbon source. The Cr2O3/carbon nanosheet
Ordered mesoporous carbons obtained by a simple soft template method as sulfur immobilizers for lithium-sulfur cells.
Electrochemical results showed that well-ordered mesoporous carbons perform better than those with a random mesopore arrangement, and the hierarchical pore structure formed by micro- and mesopores should guarantee the required fast mobility of the Li(+).
Cathode composites for Li-S batteries via the use of oxygenated porous architectures.
Electrodes containing sulfur impregnated within the pores of the MOF were found to show a marked increase in the capacity retention of Li-S cathodes and increased knowledge about the interface between polysulfide species and oxide surfaces could lead to novel approaches in the design and fabrication of long cycle life S electrodes.
Rational design of a metal–organic framework host for sulfur storage in fast, long-cycle Li–S batteries
Unlike an intercalation cathode, which has an intrinsic host structure made of redox metal sites allowing the transport of Li+/e−, sulfur as a conversion cathode requires an additional host to store
