Two-Dimensional CeO(2)/RGO Composite-Modified Separator for Lithium/Sulfur Batteries

In this work, a modified separator coated with a functional layer of reduced graphene oxide (RGO) anchored by cerium oxide (CeO(2)) nanoparticles was developed. The superior conductivity of RGO and chemical immobilization of high-ordered sulfur-related species (mainly Li(2)S(n) 4 ≤ n ≤ 8) of CeO(2)...

description In this work, a modified separator coated with a functional layer of reduced graphene oxide (RGO) anchored by cerium oxide (CeO(2)) nanoparticles was developed. The superior conductivity of RGO and chemical immobilization of high-ordered sulfur-related species (mainly Li(2)S(n) 4 ≤ n ≤ 8) of CeO(2) yielded batteries with enhanced characteristics. A remarkable original capacity of 1136 mAh g(−1) was obtained at 0.1 C with capacity retention ratio of 75.7% after 100 charge/discharge cycles. Overall, these data indicate that the separator with CeO(2)/RGO composite is promising to suppress the shuttling of polysulfides for better utilization of the active material.
