Fig. 1 Illustrative summary of major milestones towards and upon the development of graphite negative electrodes for lithium-ion batteries. Remarkably, despite extensive research efforts on alternative anode materials, 19–25 graphite is still the dominant anode material in commercial LIBs.
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.
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.
Graphite anode performance modification strategies Although graphite is an ideal anode material for LIBs, it has poor compatibility with electrolyte and high volume expansion rate, which severely limit the cycle stability and energy density of electrodes .
And because of its low de−/lithiation potential and specific capacity of 372 mAh g −1 (theory) , graphite-based anode material greatly improves the energy density of the battery. As early as 1976 , researchers began to study the reversible intercalation behavior of lithium ions in graphite.
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 .
