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 ...
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
lithium battery. Two solutions of Li2S8 in diethylene glycol dimethyl ether (DEGDME), containing
either lithium bis(trifluo ...
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 ...
A Comparative Study of Particle Size Distribution of Graphene Nanosheets Synthesized by an Ultrasound-Assisted Method
(MDPI, 2019)
Graphene-based materials are highly interesting in virtue of their excellent chemical, physical and mechanical properties that make them extremely useful as privileged materials in different industrial applications. ...
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 ...
