Chaire du Québec : Sécurité et performance : l’utilité des batteries lithium-ion dans le stockage d’énergie et le transport électrique. Avec: Karim Zaghib Professeur à l’Université McGill Département de génie des mines et des matériaux Consultant stratégique Investissement Québec
Discussion with Professor Shirley Meng about the future of the anode. Including Carbon, Silicon, and Pure Lithium Metal (C, Si, Li). Shirley has specialised in nanomaterials engineering and I think she’s the perfect person to speak with about the recent excitement around silicon anodes (nanotubes, nanowires). Today, the focus will be silicon, but we’ll also go a bit broader and talk about what we can generally expect from battery anodes in the next few years.
