Abstract Double‐shelled NiO‐NiCo 2 O 4 heterostructure@carbon hollow nanocages as efficient sulfur hosts are synthesized to overcome the barriers of lithium–sulfur (Li–S) batteries simultaneously. The double‐shelled can prevent diffusion lithium polysulfides (LiPSs) effectively. heterostructure is able promote polysulfide conversion reactions. Furthermore, thin carbon layer outside improve electrical conductivity during cycling. Besides, such unique nanocage architecture also accommodate...
Abstract The practical application of lithium‐sulfur (Li‐S) batteries remains remote because rapid capacity fade caused by the low conductivity sulfur, dissolution intermediate lithium polysulfides, severe volumetric expansion, and slow redox kinetics polysulfide intermediates. Here, to address these obstacles, a new sulfiphilic highly conductive honeycomb‐like spherical cathode host constructed from hollow metallic polar Co 9 S 8 tubes is designed. can effectively bind polysulfides for...
Tin (Sn) has been considered as one of the most promising anode materials for high-capacity lithium-ion batteries (LIBs) due to its high energy density, abundance, and environmentally benign nature. However, problems fast capacity fading at prolonged cycling poor rate hinder practical use. Herein, we report development a novel architecture Sn nanoparticle-decorated three-dimensional (3D) foothill-like graphene an in LIBs. Electrochemical measurements demonstrated that 3D Sn–graphene...
A double-hierarchical sulfur host has been synthesized in which hierarchical carbon spheres, constructed from building blocks of hollow nanobubbles used for loading sulfur, are sealed by a polar MoS<sub>2</sub> coating that is composed ultrathin nanosheets (MoS<sub>2</sub>@HCS composite).
Metal organic frameworks (MOFs)-derived porous carbon is proposed as a promising candidate to develop novel, tailorable structures polysulfides immobilizers for lithium-sulfur batteries because of their high-efficiency electron conductive networks, open ion channels, and abundant central ions that can store large amount sulfur trap the easily soluble polysulfides. However, most in MOFs-derived framework are encapsulated matrix so exposures active sites adsorb limited. To resolve this issue,...
