Abstract

An innovative design strategy for the structural and chemical synergistic encapsulation of polysulfides is proposed. Manganese dioxide nanosheet decorated hollow sulfur sphere nanocomposites are developed through a facile synthesis exhibiting ultralong cycling stability over 1500 cycles and high capacity for high-performance lithium–sulfur batteries.
