Sulfiphilic electrocatalysts dredge the polysulfide "flooding" in Li−S batteries

Demand for high-performance energy storage device is booming. There is a need for high-energy-density, rechargeable batteries, as electric vehicles, portable electronics, and sustainable energy harvesting are on the rise. Conventional lithium-ion (Li-ion) batteries are mature but limited in energy density, and don't satisfy the increasing demand for superior energy storage.
