                      publication DOI: 10.1038/s41598-025-01107-x In the
                      accompanying publication, plating and dendrite formation in
                      lithium batteries is studied using a newly developed setup
                      for dynamic nuclear polarization (DNP) operating at 0.34
                      Tesla. Electron paramagnetic resonance (EPR) sensitively
                      detects metallic Li species but misses non-paramagnetic
                      ones. Nuclear magnetic resonance (NMR) is chemically
                      selective, yet exhibits a low sensitivity under low-field
                      conditions. DNP-enhanced NMR overcomes this by transferring
                      electron spin polarization to 7Li nuclei. Here, correlative
                      X-band EPR and DNP-enhanced 7Li-NMR of plated lithium is
                      demonstrated. DNP experiments were conducted in a pulsed
                      mode to prevent excessive sample heating. The resulting
                      enhanced 7Li NMR signal allows the observation of
                      electrochemically plated lithium on copper, harvested from a
                      Cu vs. Li cell, with an enhancement ε > 400. By changing
                      the magnetic field strength by a few Gauss, the saturation
                      of the conduction EPR transition was varied, leading to an
                      altered shift of metallic 7Li. The corresponding change of
                      the DNP-polarized 7Li chemical shifts in the range from 240
                      ppm to 80 ppm, in turn, allowed an indirect,
                      saturation-based distinction of EPR species. Moreover, an
                      enhancement ε by a factor of about 2 of the 1H signal from
                      the surrounding electrolyte of electrochemically deposited
                      lithium was observed, indicating the potential to
                      investigate the solid-electrolyte interface (SEI).},
