Lithium–sulfur (Li–S) batteries are promising for next-generation high-energy energy storage systems. However, the slow reaction kinetics render mobile polysulfides hardly controlled, yielding shuttling effects and eventually damaging Li metal anodes. To improve cyclability of Li–S batteries, high-efficiency catalysts desired to accelerate polysulfide conversion suppress effect. Herein, we studied a doping system with Ni2P Ni2B as end members found B-doped catalyst that demonstrates high activity batteries. As anionic dopants, B an interesting reverse electron transfer P tunes electronic structure dramatically. The resultant exhibits short Ni–B bonds strong Ni–S interaction, donation further enhances adsorption on catalysts. S–S were activated appropriately, therefore decreasing low barrier reactions.
