WHAT ARE THE DIFFERENCES BETWEEN NATURAL AND SYNTHETIC GRAPHITE?
Natural graphite is mined from the earth and possesses a layered structure ideal for ion intercalation in batteries. This type of graphite is abundant and cost-effective, making it widely applicable in energy storage systems. However, it may contain impurities that can diminish battery performance. In contrast, synthetic graphite undergoes a meticulous manufacturing process that results in a purer and more uniform end product. This higher quality typically translates into enhanced conductivity and energy efficiency, allowing for better performance in high-demand applications. Synthetic graphite can be tailored for specific environments and requirements, whereas natural graphite is constrained by the variability in its natural state. The choice between these types will depend on the overall operational goals, cost considerations, and performance requirements of the energy storage system in question.
