Synthesis of Hierarchically Porous Carbon Monoliths with Highly Ordered Microstructure and Their Application in Rechargeable Lithium Batteries with High‐Rate Capability

Abstract In this paper, we report on Li storage in hierarchically porous carbon monoliths with a relatively higher graphite‐like ordered carbon structure. Macroscopic carbon monoliths with both mesopores and macropores were successfully prepared by using meso‐/macroporous silica as a template and using mesophase pitch as a precursor. Owing to the high porosity (providing ionic transport channels) and high electronic conductivity (ca. 0.1 S cm –1 ), this porous carbon monolith with a mixed conducting 3D network shows a superior high‐rate performance if used as anode material in electrochemical lithium cells. A challenge for future research as to its applicability in batteries is the lowering of the irreversible…
