## Description

- description: The degradation of lithium-ion batteries has become a concerning issue.
    One problem is metal ion dissolution from the cathode material, such as Mn2+ dissolution
    from spinel-type LiMn2O4 (LMO). However, direct observation of the dissolution
    process has yet to be reported. Here, we establish in-situ 1H nuclear magnetic
    resonance imaging (MRI) measurement as an efficient technique to observe Mn2+
    dissolution from a model lithium battery with LMO as the cathode. We observe an
    increase in the MRI signal intensity near the cathode, confirming the dissolution
    of Mn2+ from the cathode to the electrolyte. Moreover, we show that Mn2+ dissolution
    from LMO can be suppressed using an appropriate choice of electrolytes. We believe
    the method developed here can answer the long-time unanswered question of when,
    where, and how the metal ion dissolution occurs in the lithium-ion battery electrode
    and can be extended to other electrochemical systems.
