(Kitco News) - South Star Battery Metals (TSXV: STS) announced Tuesday that it has successfully produced uncoated and coated spherical purified graphite suitable for use as anode active material for lithium-ion batteries.

The company said that the thermal purification process resulted in 99.9993 wt % C without any of the environmental, health and worker safety issues associated with application of hydrofluoric and hydrochloric acids, which are the standard chemicals used in conventional processing of battery grade graphite.

South Star added that its spherical graphite testing resulted in yields of approximately 74%, which is twice the standard industry yield. The results indicate that the company would be very cost competitive with a less costly micronization process and exceptional spherical graphite yields, South Star said.

The company noted that it will now be constructing battery cells and performing long-term cycle testing and optimizations. 

South Star Battery Metals is Canadian graphite developer focused on the selective acquisition and development of near-term production graphite projects in Brazil. South Star's Santa Cruz graphite project, located in Southern Bahia, is the first of a series of industrial and battery metals projects that will be put into production.

Brazil is the second-largest graphite-producing region in the world with more than 80 years of continuous mining. Santa Cruz has at-surface mineralization in friable materials, and successful large-scale pilot-plant testing (>30t) has been completed. South Star is carrying its development plan towards Phase 1 production projected in Q4 2022, pending financing.
