Graphite is one of the most essential minerals used in modern rechargeable batteries. Although lithium often receives the most attention, graphite is the primary material used in the anode of almost every commercial lithium-ion battery. Without graphite, electric vehicles (EVs), smartphones, laptops, and large-scale energy storage systems would not operate efficiently.
Graphite in batteries refers to the use of natural or synthetic graphite as the anode material in rechargeable batteries. Graphite's layered crystal structure allows lithium ions to move in and out during charging and discharging, making it ideal for energy storage.
Understanding graphite demonstrates the close relationship between geology, mineralogy, materials science, electrochemistry, and clean energy technologies.
