Electrochemical Properties of Carbon Nanobeads and Mesophase-Pitch-Based Graphite Fibers as Anodes for Rechargeable Lithium-Ion Batteries

Various strategies have been devised to enhance the specific capacity (over 372 mA h g−1) and cycle life of pure carbon-based anode materials for lithium-ion batteries (LIBs). Herein, we prepared carbon nanobeads (CNBs) with inner onion-like layer structures using chemical vapor deposition. Additionally, mesophase-pitch-based graphite fibers (MPGFs) were fabricated via melt spinning method. MPGFs had a reversible 328.2 g−1 steady Coulombic efficiency after 105 cycles (at 0.05 g−1). When cycled at 0.2 A g−1, CNBs kept 586.2 256 stable efficiency. The beneficial storage lithium ions. In this work, electrochemical performance LIBs.
