Graphene Manufacturing Group – Answering Your Questions On Battery Development, THERMAL-XR, Graphene Production, Other Growth Avenues
Craig Nicol, CEO of Graphene Manufacturing Group (TSX.V:GMG – OTCQX:GMGMF) joins me to address questions you all have sent me covering all three divisions of the company: battery technology, THERMAL-XR, and lubricants.
Highlights include details on the collaboration with Rio Tinto to develop high energy density batteries, the use of graphene in various types of batteries including aluminum ion and lithium ion, and insights into the testing process. Craig also discusses the potential applications of GMG’s battery technology in the EV market, rooftop solar energy storage, and on the graphene production front, capture and utilization of hydrogen byproducts. Further questions include updates on US EPA approval for THERMAL-XR, plans for scaling up graphene production, and the overall strategic direction of GMG.
Please keep sending me all your questions for Craig. My email address is Fleck@kereport.com.

In one of his former interviews with Cory, Craig revealed that AlCl3 salt is used in the electrolyte. I’ve calculated with the aid of scientific articles on Al-ion batteries, that with such an electrolyte the max. theoretical gravimetric energy density for GMG’s Al-ion battery will be 80 Wh/kg at most, including a modest 18 % of the total weight for the packaging, separator and current collectors.
Referring to the 30 year development of the Lithium-ion battery from 90 Wh/kg on, Craig suggested that further development of the Al-ion graphene battery could further improve its energy density. No matter how much effort will be put in optimizing with different separator and other materials, the 80 Wh/kg will never be reached, which is much lower than the previous published 290 – 310 Wh/kg.
