The Role of Current Collector in Enabling the High Performance of Li/S Battery
(Wiley, 2018)
Among several factors, the nature of the current collector plays a significant role in determining the performance of Li/S battery. Carbon-based substrates gained recently increasing interest as alternative to conventional ...
Versatility of a Nitrogen-Containing Monolithic Porous Carbon for Lithium-Based Energy Storage
(Wiley, 2018)
N-containing monolithic porous carbon material with dual micro and mesoporous structures was synthesized using an innovative, cheap and easy synthesis route based on the classical resorcinol-formaldehyde synthesis. A ...
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 ...
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 ...
Untreated Natural Graphite as a Graphene Source for High-Performance Li-Ion Batteries
(MDPI, 2018)
Graphene nanosheets (GNS) are synthesized from untreated natural graphite (NG) foruse as electroactive materials in Li-ion batteries (LIBs), which avoids the pollution-generating stepsof purifying graphite. Through a ...
Almond Shell as a Microporous Carbon Source for Sustainable Cathodes in Lithium–Sulfur Batteries
(MDPI, 2018)
A microporous carbon derived from biomass (almond shells) and activated with phosphoric acid was analysed as a cathodic matrix in Li–S batteries. By studying the parameters of the carbonization process of this biomass ...
