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.
Practical challenges and future directions in graphite anode summarized. Graphite has been a near-perfect and indisputable anode material in lithium-ion batteries, due to its high energy density, low embedded lithium potential, good stability, wide availability and cost-effectiveness.
However, the performance of graphite-based lithium-ion batteries (LIBs) is limited at low temperatures due to several critical challenges, such as the decreased ionic conductivity of liquid electrolyte, sluggish Li + desolvation process, poor Li + diffusivity across the interphase layer and bulk graphite materials.
The anode, an important component of LIBs, has a significant impact on their electrochemical performance. At present, graphite, as a crystalline carbon, is the main negative electrode material for commercial LIBs , due to its abundant reserves, low cost, mature processing technology, and safety .
Lithium-ion battery anode materials include flake natural graphite, mesophase carbon microspheres and petroleum coke-based artificial graphite. Carbon material is currently the main negative electrode material used in lithium-ion batteries, and its performance affects the quality, cost and safety of lithium-ion batteries.
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.
