  text: Sodium-ion batteries are at the forefront of new, sustainable energy systems
    required for the global energy transition. 23Na in situ solid-state nuclear magnetic
    resonance spectroscopy is capable of unraveling structures in working electrochemical
    cells during the charging and discharging processes. To evaluate its suitability
    for long-term studies, local sodium environments in sodium/sodium ion cells based
    on silicon carbonitride and hard carbon materials are tracked for up to 49 cycles
    (228.5?h). The formation of dendrites as well as the decay of a secondary metallic
    sodium species is observed, and local structures are analyzed up to the point
    of capacity degradation and cell failure. Initial points of cell breakdown are
    reflected in the NMR data by characteristic changes in signal intensities, whereas
    the degradation of the cells is reflected by a cease to periodic signal intensity
    fluctuations. Meanwhile, ex situ 23Na NMR spectra of the deactivated cells reveal
    a complex range of environments for sodium ions.
