  • Towards a High-Power Si graphite Anode for Lithium Ion

    Silicon-based anodes are extensively studied as an alternative to graphite for lithium ion batteries. However silicon particles suffer larges changes in their volume (about 280 ) during cycling which lead to particles cracking and breakage of the solid electrolyte interphase. This process induces continuous irreversible electrolyte decomposition that strongly reduces the battery life.
