Bioinspired urchin-like murray carbon nanostructure with protection shell for advanced lithium-sulfur batteries

Carbons derived from resole-type phenolic resins for use in lithium–sulfur batteries: templating the resins with sulfur leads to enhanced cell performance

“…Doping porous carbons with nitrogen has been found in the literature to better allow surface chemisorption of the active material species in LSBs. 30 Nitrogen was not detected for Reg-600.…”

Cobalt-based current collectors for flexible electrodes and their application in lithium–sulfur batteries

“…5,6 For example, a mesoporous hierarchical NiCoSe 2 –NiO composite self-supported on a carbon nanoarray electrode achieves a cycle capacity of 919.43 mA h g −1 at 0.2C with a high sulfur loading (3.5 mg cm −2 ). 7 In addition, 3D porous frameworks, 8 doping polar materials 9 and doping polar groups 10 can enhance the electron/ion conductivity between the flexible electrode's interior and interface; doping SO 4 2− anions in a 3D PPy-SO 4 inter-connected framework skeleton enhanced the conductivity of PPy to accelerate the electrode reaction. 11 However, due to the lack of current collectors, the electronic conduction in the electrode can only rely on the conductive skeleton of the electrode.…”

High Young’s Modulus Li6.4La3Zr1.4Ta0.6O12-Based Solid Electrolyte Interphase Regulating Lithium Deposition for Dendrite-Free Lithium Metal Anode

“…With the progress of science and technology, people have higher requirements for high energy density devices. Li metal anode is considered to be the most promising anode material due to its theoretical specific capacity of up to 3860 mA h g –1 and a low electrochemical potential of 3.04 V. − However, due to the high reactivity of Li metal, it can react with the electrolyte to form a solid electrolyte interface (SEI) film on the surface during cycling. The spontaneous SEI film was shown to have a bilayer structure.…”
