Regulating adsorption ability toward polysulfides in a porous carbon/Cu₃P hybrid for an ultrastable high‐temperature lithium–sulfur battery

Lithium–sulfur batteries (LSBs) can work at high temperatures, but they suffer from poor cycle life stability due to the “shuttle effect” of polysulfides. In this study, pollen‐derived porous carbon/cuprous phosphide (PC/Cu 3 P) hybrids were rationally synthesized using a one‐step carbonization method using pollen as the source material, acting as the sulfur host for LSBs. In the hybrid, polar Cu 3 P can markedly inhibit the “shuttle effect” by...
