Identification of Li-Ion Battery SEI Compounds through <sup>7</sup>Li and <sup>13</sup>C Solid-State MAS NMR Spectroscopy and MALDI-TOF Mass Spectrometry
Solid-state (7)Li and (13)C MAS NMR spectra of cycled graphitic Li-ion anodes demonstrate SEI compound formation upon lithiation that is followed by changes in the SEI upon deli...
