Researchers at Purdue University soaked a plastic bag in sulfur-containing solvent and put it in a microwave to boost the temperature needed for transformation into low-density polyethylene promoting the sulfonation and carbonization of the plastic. It induced a higher density of pores for catching polysulfide and made it into porous sulfonated carbon (PSC) to divide the lithium and sulfur halves of a battery. When a PSC layer was utilized as an interlayer in lithium–sulfur batteries, the sulfur cathode delivered an improved capacity of 776 mAh g–1 at 0.5C and an excellent cycle retention of 79% over 200 cycles…read more.
