Effect of nanosized Mg0.6Ni0.4O prepared by self-propagating high temperature synthesis on sulfur cathode performance in Li/S batteries

Sepiolite-sulfur as a high-capacity, high-rate performance, and low-cost cathode material for lithium–sulfur batteries

“…The interface chargetransfer resistance (R ct ) and activated adsorption resistance (R t ), however, decrease after 500 cycles, and they are approximately proportional to each other. It has been reported that metal oxides may lead to the formation of an interfacial layer, favoring the electrochemical stability of the system and resulting in reduction in charge-transfer resistance as cycles increase [21,22]. Metal oxides in sepiolite may contribute to such charge-transfer resistance reduction we observed.…”

Mg0.6Ni0.4O hollow nanofibers prepared by electrospinning as additive for improving electrochemical performance of lithium–sulfur batteries

“…Besides, metal oxides for polysulfides entrapment also have attracted significant attention, such as Mg 0. 8 [25,26]. It was concluded that the nanosized Mg 0.6 Ni 0.4 O had not only the polydulfides adsorption but also exhibited the catalytic effect on the Li/S redox reaction.…”

High performance sulfur/nitrogen-doped graphene cathode for lithium/sulfur batteries

“…Lithium/sulfur (Li/S) batteries, due to their high theoretical specific capacity of 1672 mAh g −1 , high theoretical specific energy of 2600 Wh kg −1 , and environmentally friendliness, abundant and cheap sulfur resources, have received great attention as one of the most promising energy storage systems [1,2].…”
