Breaking the Trade-Off Between Electrical Conductivity and Mechanical Strength in Bulk Graphite Using Metal-Organic Framework-Derived Precursors.

ABSTRACT: High-performance bulk graphite (HPBG) that simultaneously integrates superior electrical conductivity and excellent strength is in high demand, yet it remains critical and challenging. Herein a novel approach is introduced utilizing MOF-derived nanoporous metal/carbon composites as precursors to circumvent this traditional trade-off. The resulting bulk graphite, composed of densely packed multilayered graphene sheets functionalized with diverse cobalt forms (nanoparticles, single atoms, and clusters), exhibits unprecedented electrical conductivity in all directions (in-plane: 7311 S cm⁻¹, out-of-plane: 5541 S cm⁻¹) and excellent mechanical strength (flexural: 101.17±5.73 MPa, compressive: 151.56±2.53 MPa). Co nanoparticles act as autocatalysts and binders, promoting strong interlayer adhes
