The inherent low-capacity problem of graphite necessitates the need for higher-capacity alternatives to meet the market demand.
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.
