Spherical graphite (SPG) is ideal for use as a raw material for anodes. Due to its high tap density, high charging is achieved and consequently energy density is higher.
The spheronisation process decreases the surface area to allow more graphite into a smaller volume. This creates a smaller, denser, more efficient anode product for the battery. It also increases the rate at which the cell can be charged and discharged.
With the expected growth in demand for lithium-ion batteries for markets such as electric vehicles, demand for spherical graphite is also expected to increase at a rapid pace.
