Sulfur/carbon cathode material chemistry and morphology optimisation for lithium–sulfur batteries
Tayeba Safdar, Chun Huang
Abstract
at 0.1C was obtained with a capacity retention of ∼50% after 100 cycles. The improved electrochemical performance is rationalised as an increased number of C-S bonds in the composite material, optimum surface area, pore size and pore volume, and more homogeneous cathode microstructure in the TC10.5 cathode.
