Abstract
Metal-organic frameworks (MOFs) are attractive electrode material candidates for lithium-ion batteries (LIBs) and are garnering significant interest due to their tunable pore size and intriguing electrochemical properties. A border-rich iron (Fe3+) hexacyanocobaltate (FeHCCo) MOF is synthesized via a facile and low-cost co-precipitation method and evaluated as a cathode material for LIBs. The MOF delivered reversible capacities corresponding to 136 and 57  mAh g− 1 at 0.63 and 6.25C, respectively. Furthermore, a lithiation capacity of 116  1 at 1.25C was maintained with a Coulombic efficiency of 99.6%. The high electrochemical performance can be attributed to the highly reversible open-framework crystal texture of border-rich FeHCCo, which may provide new insights on the application of MOFs as viable electrode materials in rechargeable LIBs.
