Abstract
Natural flake graphite is widely used as anode material of commercial lithium‐ion batteries. In contrast, natural microcrystalline graphite (MG) has not been in practical application. This work systematically investigates the structure‐property relationship between the intrinsic structure of MG and its electrochemical performance. The results indicate that that both morphology and particle size significantly affect its electrochemical performance. The small‐particle‐sized and spheroidized MG can provide abundant pathways for the rapid transport of Li + , contributing to a higher rate capability because MG with a short‐range ordered and long‐range disordered structure is more conducive to the rapid migration of Li + .Keywords
