Investigating the Existence of a Cathode Electrolyte Interphase on Graphite in Dual‐Ion Batteries with LiPF6‐Based Aprotic Electrolytes and Unraveling the Origin of Capacity Fade

Investigating the Existence of a Cathode Electrolyte Interphase on Graphite in Dual‐Ion Batteries with LiPF6‐Based Aprotic Electrolytes and Unraveling the Origin of Capacity Fade

This study elucidates the presence of a cathode electrolyte interphase (CEI) at graphite positive electrodes (PEs) and assesses its impact on the performance of dual‐ion batteries, being promising candidates for cost‐efficient and sustainable stationary energy storage. Indeed, electrolyte oxidation...
