Biomass-derived carbon/γ-MnO2 nanorods/S composites prepared by facile procedures with improved performance for Li/S batteries
(Elsevier, 2018)
The promising prospects of the Li/S battery, due to its theoretical energy density of about
2500 Wh kg─1, are severely limited by two main weaknesses: the poor conductivity of S and
the solubility of the polysulphides ...
A new lithium-ion battery using 3D-array nanostructured graphene-sulfur cathode and silicon oxide-based anode
(Wiley, 2018)
In this work we report an efficient lithium-ion battery using enhanced sulfur-based cathode and silicon oxide-based anode as novel energy-storage system. The sulfur-carbon composite, exploiting graphene carbon with 3D array ...
High Capacity Semi-Liquid Lithium Sulfur Cells with Enhanced Reversibility for Application in New-Generation Energy Storage Systems
(Elsevier, 2019)
Semi-liquid configuration of sulfur cell is proposed as simple strategy to develop high-energy

Physical activation of graphene: An effective, simple and clean procedure for obtaining microporous graphene for high-performance Li/S batteries
(Springer Verlag, 2019)
Graphene nanosheets are a promising scaffold to accommodate S for achieving high performanceLi/S battery. Nanosheet activation is used as a viable strategy to induce a micropore system and further improve the ...
Lithium sulfur battery exploiting material design and electrolyte chemistry: 3D graphene framework and diglyme solution
(Elsevier, 2018)
Herein we investigate a lithium sulfur battery suitably combining alternative cathode design and relatively safe, highly conductive electrolyte. The composite cathode is formed by infiltrating sulfur in a N-doped 3D graphene ...
