Different carbon processes for lithium-sulfur batteries

In this work, different carbon modification processes have been employed and the results compared with unmodified Super-P carbon. The active materials were used in respective cathodes for Li/S batteries. electrochemical performance was studied by galvanostatic charge-discharge cycling, cyclic voltammetry, impedance spectroscopy rate capability. CV measurements showed modified carbons started out charging discharging at set voltages, their peaks broadening as part of cycling-induced decay. It found that processed nitric acid delivered highest capacity retention after 100 cycles C/10. indicate could be promote decrease shuttle effect.
