Fig. 1. History and development of graphite negative electrode materials. With the wide application of graphite as an anode material, its capacity has approached theoretical value. The inherent low-capacity problem of graphite necessitates the need for higher-capacity alternatives to meet the market demand.
And as the capacity of graphite electrode will approach its theoretical upper limit, the research scope of developing suitable negative electrode materials for next-generation of low-cost, fast-charging, high energy density lithium-ion batteries is expected to continue to expand in the coming years.
In addition, the known partial exfoliation of some SFG6-HT graphite particles in the electrode, 26 which is combined with a significant volume increase of the graphite particles, increases the mechanical stress on the electrode and thus deteriorates the particle-particle contact in the electrode during the first electrochemical lithium insertion.
The graphite anode material for lithium-ion batteries uses a crystalline layered graphite-based carbon material. It works in synergy with the cathode material to achieve multiple charging and discharging of the lithium-ion battery.
The key parameters found to influence the performance of a graphite negative electrode were the loading, the thickness, and the porosity of the electrode. © 2005 The Electrochemical Society. All rights reserved. Export citation and abstract BibTeX RIS
The early lithium plating behavior of graphite anode is due to the diverse morphology and uneven distribution of graphite particles. The uneven distribution of the contact surface with the electrolyte leads to the uneven filling of lithium ions in the graphite particles, resulting in the significant growth of lithium coatings.
