      abstract     = {Enhancing lithium-ion battery technology in terms of
                      specific capacity and charging time is key for the
                      advancement of the electrification of transportation.
                      Particularly for fast charging, inhomogeneous deposition of
                      metallic lithium, for example on commercial graphite or
                      metallic lithium anodes, leads to cell degradation and
                      safety issues. To understand the underlying mechanisms and
                      develop counter-measures, non-invasive online detection
                      techniques providing satisfactory time resolution are
                      crucial. Here, we demonstrate in operando pulse electron
                      paramagnetic resonance to observe transient processes during
                      pulsed fast charging in cells with metallic lithium anodes.
                      Sampling timescales of 100 ms enable real-time monitoring
                      of the formation and evolution of porous lithium during and
                      after charging pulses. It was observed that the generated
                      morphology continued to evolve after the end of a charging
                      pulse, whereby surface features were fusing with a time
                      constant that was slower than their formation.},
