- Abundant and sustainably sourced U.S. domestic natural graphite feedstock
- Minimum 99.95% graphite purity and 99.99% demonstrated purity rate
- Proprietary WWR graphite purification process with advantages over Hydrofluoric Acid (HF) based process on multiple key attributes
- Three types of graphite product serving a wide array of battery chemistries (below)
Our Coated Spherical Purified Graphite (CSPG) is made with natural graphite and used for lithium-ion anode. We anticipate a rapidly increasing usage of natural graphite that can mitigate the risks associated with cost fluctuations and supply challenges of artificial graphite.
DEXDG is a differentiated conductivity enhancer with a high surface area which enables fast charging and enhances the mechanical integrity of anode during charge/discharge cycles.
Our Delaminated Expanded Graphite (DEXDG) and Purified Micronized Graphite (PMG) are key performance-enhancing additives for advanced lead-acid batteries. Combined with the expander in negative electrode, these additives can offer an advantage over carbon black by improving charge/discharge capacity and cycling performance.
Our PMG and DEXDG are used as conductivity enhancers for alkaline batteries. Our internal tests have generated promising data exhibiting improved performance over other natural graphite products, as well as over artificial graphite.
Lithium Primary Battery
Lithium primary batteries are long-lasting non-rechargeable batteries that support our modern lifestyles in many ways. Its applications include automotive (TPMS), medical and military applications essential to our lives and to national security. Our PMG and DEXDG are key performance enhancers for these important market segments.
