  2. Self-reporting of Mn ion dissolution and self-stabilization of cathode-electrolyte interface in lithium ion batteries

    … self-reporting strategies that enable in situ or operando characterization of cathodic Mn dissolution, which is a major cause of the capacity fade for some cathodes, and release of battery additives triggered by electrolyte degradation to self-stabilize the cathode-electrolyte interface. Lithium …
