Aiming at the common bottleneck problem that graphite anodes of lithium-ion batteries are prone to lithium plating during fast charging and low-temperature charging, which poses potential battery safety hazards, this study leverages the respective advantages and preliminary cooperation of Northwestern Polytechnical University, The Hong Kong Polytechnic University, and Shaanxi Coal Research Institute in battery material R&D and device manufacturing. The work aims to reveal the lithium plating inhibition mechanism of MOF-derived carbon modified graphite, clarify the influence rules of surface phase composition, pore structure, doped elements, electronic state and other properties of MOF-derived carbon coated graphite on lithium plating behavior, and explore the internal correlation among its surface physicochemical properties, anode SEI film and lithium plating characteristics. The dataset contains the electrochemical performance data of MOF-derived carbon coated graphite anodes, which were measured and calculated in accordance with the relevant test methods specified in "GB/T 24533-2019 Graphite Anode Materials for Lithium-Ion Batteries" during the design and controllable preparation experiments of lithium plating-resistant MOF-derived carbon coated graphite anodes. The specific content includes original experimental record data, charts, third-party test reports corresponding to indicators such as specific capacity and first-cycle coulombic efficiency, as well as 1 academic paper and 1 patent that support these indicators. Specifically, the dataset consists of the original paper and its supporting data, original patent document, third-party test report, and indicator supporting data. The data formats are .xlsx and .pdf, with a total folder size of 9.17 MB.
