A three-dimensional conductive cross-linked all-carbon network hybrid as a sulfur host for high performance lithium-sulfur batteries

A Porous Carbon Polyhedron/Carbon Nanotube Based Hybrid Material as Multifunctional Sulfur Host for High‐Performance Lithium‐Sulfur Batteries

“…However, the commercial application of Li−S batteries is still impeded by a multitude of intractable issues. These obstacles mainly include the low utilization of active material and sluggish electrochemical reaction kinetics originating from the insulativity of sulfur and Li 2 S/Li 2 S 2 , fast capacity decay, perishing cycling stability and poor Coulombic efficiency induced by the large volumetric variation and dissolution/shuttle behaviors of polysulfides …”

“…These obstacles mainly include the low utilization of active material and sluggish electrochemical reaction kinetics originating from the insulativity of sulfur and Li 2 S/Li 2 S 2 , fast capacity decay, perishing cycling stability and poor Coulombic efficiency induced by the large volumetric variation and dissolution/ shuttle behaviors of polysulfides. [5,6] In the past few years, to meet these challenges, strenuous efforts have been dedicated to developing novel sulfur host materials, especially nanostructured porous conductive carbon. A variety of porous carbon/sulfur composite materials have been explored and investigated which exhibited excellent electrochemical performance.…”

Characterization of Hierarchical Porous Carbons Made from Bean Curd via K2CO3 Activation as a Supercapacitor Electrode

“…Electrode material is one of the main SC components that has dominant role in determining SC performance. Activated carbon (AC) in particular has been widely studied and used as electrode materials in SC given its high specific surface area (SSA), high chemical stability, high electrical conductivity, low cost, and simple preparation procedure . Biomass is presently one of the most preferred precursors for AC preparation given its renewable characteristic and abundant availability .…”

“…Activated carbon (AC) in particular has been widely studied and used as electrode materials in SC given its high specific surface area (SSA), high chemical stability, high electrical conductivity, low cost, and simple preparation procedure. [3][4][5] Biomass is presently one of the most preferred precursors for AC preparation given its renewable characteristic and abundant availability. [6] One of the main research and development efforts in the SC field has been geared towards the development of new, facile method to convert biomass into highly porous activated carbon with well-defined nanostructure.…”

One‐Step Synthesis of a Coral‐Like Cobalt Iron Oxyhydroxide Porous Nanoarray: An Efficient Catalyst for Oxygen Evolution Reactions

“…The depletion of fossil energy has caused serious environmental pollution, and thus it is urgent to explore high-efficiency clean energy and develop new technologies. [1][2][3][4][5] Hydrogen energy, considered as a kind of important renewable energy, has drawn people's widespread attention. [6] As mentioned in several reported researches, electrocatalytic water splitting are regarded as one of the most promising approaches to the production of hydrogen, which proves that water splitting can be applied further to the industry.…”
