Three‐dimensional ordered mesoporous/macroporous carbon sphere arrays (MMCSAs) are synthesized and then used as a catalyst for Li−O2 batteries. The hierarchical porous structure of the MMCSAs not only facilitates electrolyte immersion and Li+ diffusion but also provides an effective space for O2 dif...
