In article number 2003104, Seung Jae Yang and co‐workers report 3D graphite nanoballs (GNBs) enabled by the coordination of tannic acid and atomically distributed nickel ion. The GNB facilitates rapid and stable delivery of lithium ions through exposed edges in multiple directions.
Continuous efforts have been made to achieve nanostructured carbon materials with highly ordered graphitic structures using facile synthetic methods. 3D graphite nanoballs (GNBs) are synthesized by the low‐temperature pyrolysis of a non‐graphitizable precursor, tannic acid (TA). Abundant phenol groups on TA bind to Ni2+ to form metal‐phenolic coordination, which renders each Ni cation to be atomically...
