## Description

- description: While high-voltage operation of mid-Ni layered oxide cathodes in full-cell
    Li-ion batteries is essential for achieving high energy density, it inevitably
    accelerates electrode degradation, ultimately resulting in capacity loss. However,
    the underlying degradation mechanisms under high-voltage conditions remain poorly
    understood. In this study, we reveal that anode slippage – induced by cross-talk-driven
    surface degradation – is the dominant factor in capacity fade during high-voltage
    (4.35 or 4.40 V) cycling of single-crystal mid-Ni layered oxide (SC-NCM)/graphite
    pouch full-cells. Electrochemical and post-mortem analyses show that, although
    high-voltage operation induces cathode surface degradation, including lattice
    oxygen loss and phase transitions, its direct impact on capacity loss is relatively
    minor compared to that of the anode. Instead, anode degradation is primarily caused
    by cross-talk effects from cathode Ni dissolution, which promote the accumulation
    of irreversible organic byproducts – such as LiOx and Li2CO3—within the solid
    electrolyte interphase (SEI) layer of the graphite anode. This leads to increased
    resistance and reduced anode electrochemical activity, disrupting electrode balance
    and accelerating full-cell capacity fade. These findings highlight the critical
    role of anode degradation in high-voltage operation and emphasize the importance
    of mitigating cross-talk effects. A comprehensive understanding of cross-talk
    – induced anode slippage is therefore critical for the rational design of high-voltage
    mid-Ni full-cell systems with long-term durability.
