Insights Into the Kinetics and Storage Mechanism of Quasi‐Metallic Lithium Clusters in the Closed‐Pore Structure of Microcrystalline Cellulose‐Derived Hard Carbon

Liang‐Chieh Tseng, Yun Lin, Yu‐Chun Chen, Yi‐Cheng Liao et autres

ABSTRACT Hard carbon (HC) is a promising negative electrode material whose multiscale microstructure enables high theoretical capacity. However, its Li‐storage mechanism remains insufficiently understood, particularly the origin of the low‐potential plateau. Here, microcrystalline cellulose‐derived HCs exhibiting pronounced low‐potential plateau are systematically investigated. …
