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.
Commercial LIBs require 1 kg of graphite for every 1 kWh battery capacity, implying a demand 10–20 times higher than that of lithium . Since graphite does not undergo chemical reactions during LIBs use, its high carbon content facilitates relatively easy recycling and purification compared to graphite ore.
Lightweight lithium-ion batteries (LIBs) with a high operating voltage and long life cycle are in demand for the success of electric vehicles and a sustainable energy economy [ 1, 2 ]. Graphite has been widely used as an anode material because of its long cycle life and stability [ 3 ].
