摘　　要：炭气凝胶材料具有三维层次化多孔网络、较快的电子/离子传输速度、卓越的物理化学性能和循环稳定性,被认为是电化学储能领域中最有前景的碳基材料之一。此外,炭气凝胶的这些优势也使其在复合材料的应用中发挥了巨大潜力。本综述总结了近年来三维炭气凝胶的合成方法、功能化方法及其在碱金属离子电池中的研究进展。Carbon aerogels with a three-dimensional(3D)hierarchical porous network could be promising carbon-based materials for electrochemical energy storage systems because of their rapid electron/ion transport,remarkable physicochemical stability and excellent cycling performance.They have also been used to host electrochemical active materials(transition metal oxides/sulfides/phosphides)in pores to improve the electron conductivity and to buffer large volume changes.In this review,recent advances in their synthesis,functionalization/modification and use in alkali-metal ion batteries,either alone or as composites,are summarized.The challenges for future research on carbon aerogels are discussed and development opportunities are proposed.
