Quick capacity loss due to the polysulfide shuttle effects and poor rate performance caused by low conductivity of sulfur have always been obstacles to the commercial application of lithium sulfur batteries. Herein, an in‐situ doped hierarchical porous biochar materials with high electron‐ion conduc...
