development of graphene-wrapped silicon anodes Dr. Pope added: “Silicon is poised to replace graphite as the dominant anode material in current Li-ion and future, next-generation batteries. However, silicon expands by over 300% when the battery is charged and discharged, which has limited commercialization efforts. Our lab, through ongoing efforts supported by Zentek and the Natural Sciences and Engineering Research Council of Canada, has developed an improved method to enable high capacity, high cycle-life anodes by encapsulating them in a protective, crumpled graphene shell using a simple spray drying approach often used to generate much of the world’s dry powders. We look forward to our continued collaboration with Zentek which we hope will soon lead to a dominant, commercial anode technology.”
Zentek, along with grants from the Natural Sciences and Engineering Research Council of Canada (NSERC), has been funding the research and development of this novel graphene-wrapped silicon anode.
