合成三维有序介孔/大孔碳球阵列（MMCSA），然后用作Li-O-2电池的催化剂。 MMCSA的分层多孔结构不仅有利于电解液浸没和Li+扩散，而且为O-2扩散和O-2/Li2O2转化提供了有效的空间，从而有效提高了Li-O-2电池的性能。
Three-dimensional ordered mesoporous/macroporous carbon sphere arrays (MMCSAs) are synthesized and then used as a catalyst for Li-O-2 batteries. The hierarchical porous structure of the MMCSAs not only facilitates electrolyte immersion and Li+ diffusion but also provides an effective space for O-2 diffusion and O-2/Li2O2 conversion, and thus efficiently improves the performance of Li-O-2 batteries.
