Free QuoteAs a crucial anode material, Graphite enhances performance with significant economic and environmental benefits. This review provides an overview of recent advancements in the modification techniques for graphite materials utilized in lithium-ion and sodium-ion batteries.
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.
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.
Graphite for batteries currently accounts to only 5 percent of the global demand. Graphite comes in two forms: natural graphite from mines and synthetic graphite from petroleum coke. Both types are used for Li-ion anode material with 55 percent gravitating towards synthetic and the balance to natural graphite.
Subsequently, it focuses on the modification methods for graphite anode materials in sodium-ion batteries, including composite material modification, electrolyte optimization, surface modification, and structural modification, along with their respective applications and challenges.
Negative materials for next-generation lithium-ion batteries with fast-charging and high-energy density were introduced. Lithium-ion batteries (LIB) have attracted extensive attention because of their high energy density, good safety performance and excellent cycling performance.
