Testing showed that Northern's anode material can be charged to high values which remain stable with high Coulomb efficiency under various discharge conditions. ProGraphite concluded that Northern's anode material is very well suited for the manufacture of high capacity, durable, long-life lithium-ion batteries.ProGraphite is one of the world's leading graphite R&D laboratories with several decades of professional expertise and experience. Its test results demonstrated that Bissett Creek BAM can be charged to lithiation values above 362 mAh/g which shows that the capacity of the batteries will be excellent. The delithiation (discharging) performance was also excellent as the batteries delivered stable, high values with a very high Coulomb efficiency under various test conditions. Northern's BAM also proved to be very robust. Even after charging/discharging several times at 10C (i.e. complete charging in only six minutes) and after many cycles, the Coulomb efficiency remained at a very high, constant level indicating almost no degradation of the anode material. This performance is better than many commercial natural or synthetic grades.Northern CEO, Greg Bowes commented that \"graphite is generally evaluated based on flake size and purity but when it comes to making batteries, many other factors are critical and not all concentrates are suitable. High bulk density translates into higher capacity batteries, and ease of purification and high yield result in lower costs. Testing by ProGraphite provides independent, third-party validation that Bissett Creek concentrates are of the highest quality.\"Electrochemical testing was the third phase in evaluating the use of Northern's concentrates in the manufacture of BAM and follows very successful spheronization and purification testing. ProGraphite demonstrated that material from the Bissett Creek deposit is very suitable for the spheroniz...
