Graphene/SulfurGraphene Composite Structure

Graphene/sulfurgraphene composite structure as a cathode material is synthesized with a facile method. Graphene can provide a more efficient conductive network for sulfur and improve the coulombic efficiency of the battery. On the other hand, it may also show the anchoring effect on sulfur, which reduces the loss of sulfur and improves the cycling performance of the battery. Due to the unique

Recent progress in the synthesis of graphene/CNT

A high power density of about 68 mW/cm 2 was achieved when the PtRu/graphene-MWCNTs and Pt/graphene-MWCNTs were used as electrocatalyst anode and cathode respectively. Similarly, Kwok et al[ 255 ] produced a porous anode based on RuPt core-shell nanoparticles decorated graphene/CNT composites for the DMFCs.

A chemically stabilized sulfur cathode for lean

Sulfur is a promising cathode material for rechargeable lithium batteries due to its high capacity, low cost, abundance, and high sustainability. However, lithium sulfur batteries suffer from poor cycle life and low energy density under lean electrolyte conditions because of the dissolution of lithium polysulfide intermediates. Here, we report that the chemical bonding between sulfur and
