Mechanistic understanding of interphase-driven ageing in silicon anodes

Key Points

• Ageing processes in silicon anodes are significantly influenced by interphase interactions, which degrade performance.
• Electrochemical performance metrics show that silicon anodes face considerable ageing issues under typical operation conditions.
• Observational analysis of interphase behaviour highlights key chemical alterations during lithium-ion cycling.
• Understanding interphase mechanisms may lead to enhanced silicon anode designs and longer-lasting battery performance.
