Inhibiting Polysulfide Shuttling with a Graphene Composite Separator for Highly Robust Lithium-Sulfur Batteries

(Joule 2, 2091–2104; October 17, 2018) In the originally published version of this article, the Randles-Sevcik equation (Equation 1) was incorrectly written asIP=2.69×105n1/2ADLi1/2v1/2CLi. The equation has been corrected online and appears below:IP=2.69×105n3/2ADLi1/2v1/2CLi. The authors regret this error. Inhibiting Polysulfide Shuttling with a Graphene Composite Separator for Highly Robust Lithium-Sulfur BatteriesLei et al.JouleAugust 9, 2018In BriefA graphene composite separator with abundant sulfonic groups is prepared by directly polymerizing hexamethylene diisocyanate with reduced graphene oxides and sodium lignosulfonates, followed by a simple filtration process. The rich negative charge in the composite separator effectively suppresses the translocation of the negatively charged polysulfide ions to enable highly robust lithium-sulfur batteries.
