ZEN GRAPHENE SOLUTIONS REPORTS A 324% INCREASE IN ANODE DISCHARGE CAPACITY IN PRELIMINARY BATTERY TESTING RESULTS
Zen Graphene Solutions Ltd. and its research partners, Deutsches Zentrum fur Luft-und Raumfahrt (the German aerospace centre (DLR)) and Kal Tire, have provided an update on their preliminary battery development results at the University of British Columbia, Okanagan campus (UBC-O), performed by Dr. Lukas Bichler and his team. Initial results showed that the addition of 5 per cent Zen-reduced graphene oxide (rGO) into carbon black derived from recycled tires from Kal Tire resulted in a 324-per-cent increase in the anode discharge capacity in comparison with the current industry standard anode material, Super P carbon powder, which is used in numerous battery applications as a conductive additive.
Dr. Francis Dube, chief executive officer, commented: "This environmentally friendly process utilizes recycled used tires and produces carbon black, which is potentially suitable for use as an anode material in rechargeable batteries. This could potentially decrease the cost of anode material, which is currently the highest-cost component of these batteries. These are excellent preliminary research results and Zen will continue to work with Dr. Bichler and his team, along with DLR and Kal Tire, to optimize these results."
Follow-up research will now focus on optimizing these preliminary results to produce a new environmentally friendly, lower-cost and higher-capacity anode material. The carbon black material derived from the Kal Tire tires yielded an anode material with an energy discharge capacity of 115 milliampere hours per gram (mAh/g), the same as industry standard carbon (Super P). The addition of 5 per cent rGO from Zen to the carbon black anode material increased the capacity from 115 mAh/g to 488 mAh/g, while a battery consisting of 100 per cent rGO had a capacity of 840 mAh/g. These results were presented during a two-day summit at UBC-O. Future opportunities in next-generation batteries and other applications were discussed between the three industrial partners, along with the potential for strong collaborations between the Canadian and European partners. The collaboration also focuses on the international exchange of students and research scientists to rapidly develop these new battery anode materials.
