Graphite materials with a high degree of graphitization based on synthetic or natural sources are attractive candidates for negative electrodes of lithium-ion batteries due to the relatively high theoretical specific reversible charge of 372 mAh/g.
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.
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.
Graphite is a perfect anode and has dominated the anode materials since the birth of lithium ion batteries, benefiting from its incomparable balance of relatively low cost, abundance, high energy density, power density, and very long cycle life.
Let’s consider the anode. The graphite material of the anode is placed in sheets or layers and reversibly allows the placement of lithium ions into (intercalation) or out of (deintercalation) during charging and discharging, respectively.
