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.
In particular, the Li deposition can damage the integrity of the SEI, leading to a decline in battery performance and increased safety risks. [2, 3] Additionally, the specific surface area of the graphite has a great influence in preventing Li plating and the formation of the SEI.
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.
Identifying stages with the most significant environmental impacts guides more effective recycling and reuse strategies. In summary, the recycling of graphite negative electrode materials is a multi-win strategy, delivering significant economic benefits and positive environmental impacts.
