Production
Spherical graphite (SpG), also known as battery-grade graphite, is the product that is consumed as an anode in lithium-ion batteries. Flake graphite concentrate is processed into ultra-high-purity (>99.95% C) with particle sizes ranging from 10 micron to 25 micron.
These are then used as a battery anode material. It is it’s special electrical conductivity that makes spherical graphite a critical component in anode manufacture. Graphite represents just under 50% of battery minerals in a lithium-ion battery.
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.
| Fixed Carbon (%) | Particle Shape | Particie Size | Tap Density (g/cc) | BET Surface Area (m²/g) | Moisture (%) |
| 99.9-99.98 | Spherical or Potato Shape | D50: 5-25um | 0.9-1.05 | 4-8 | <0.5 |
As global demand for battery graphite rapidly expands, there is an increasing customer requirement for new, more geographically diversified and environmentally sustainable sources of high-quality supply. Feedback from lithium-ion battery anode manufacturers indicates that demand from e-mobility and energy storage markets will continue to grow strongly.
