Problem Addressed

Traditional crystalline oxide cathodes, such as LiCoO­2+, LiMn2O4, and LiFePO4, etc., have low practical capacity (<200 mAhg-1) and cannot satisfy the demands of the increasing capacity of lithium ion batteries. Li2S nanoparticles synthesized and dispersed on reduced graphene oxide cathode paper for a high-performance lithium sulfur battery achieve a high reversible capacity of 597mAhg-1 at a high rate of 7C, which proves that Nanosized Amorphous Solid-Oxidant Cathodes (NASOCs) can improve rate capability and lower over-potential.
