Electrochemical characterization of the sulfur-graphenic composite cathodes was conducted in order to assess the performance of the material as a potential cathode in LSB applications. Figure and show the cycle life of a typical cell comprised of the laser-induced cathode material, which were cycled at 0.07 and 0.7 A g -1 , respectively. The cell which ran at low rates exhibited excellent reversible capacity of 1000 mAh g -1 , with an average coulombic efficiency of 99 %, and capacity retention of 73.1% over 420 cycles. The cell portrayed in Figure , which was charged/discharged at significantly faster rates, showed initial reversible capacities of 575 mAh g -1 , and over 1500 cycles maintained remarkable capacity at a rate of 73.9%.
