摘　　要：Hollow carbon-based nanostructures(HCNs)have found broad applications in various fields,particularly rechargeable batteries.However,the syntheses of HCNs usually rely on template methods,which are time-consuming,low-yield,and environmentally detrimental.Metal-organic frameworks(MOFs),constructed by organic ligands and inorganic metal nodes,have been identified as effective platforms for preparing HCNs without adding extra templates.This review summarized the recent progress in template-free synthesis of HCNs enabled by MOFs and their applications in rechargeable batteries.Different template-free strategies were introduced first with mechanistic insights into the hollowing mechanism.Then the electrochemical performances of the HCNs were discussed with highlight on the structure-function correlation.It is found that the built-in cavities and nonporous for HCNs is of critical importance to increase the storage sites for high capacity,to enhance charge and mass transport kinetics for high-rate capability,and to ensure the resilient electrode structure for stable cycling.Finally,the challenges and opportunities regarding MOFs-derived HCNs and their applications in rechargeable batteries were discussed.
