      abstract     = {Pure, i.e., linear poly(ethylene oxide)-based solid polymer
                      electrolyte (PEO-based SPE) as a common benchmark system for
                      Li metal batteries (LMBs) is frequently assumed to be
                      unsuitable for high voltage applications e.g., with
                      LiNi0.6Mn0.2Co0.2O2 (NMC622)-based cathodes. In fact, a
                      destructive failure appears immediately after cell
                      operation, seen by a random-like “voltage noise” during
                      charge, rendering continuous charge/discharge cycling in
                      e.g., NMC622||Li cells not possible. Counterintuitively,
                      this failure is a result of short-circuits in the course of
                      e.g., Li dendrite penetration. It is shown that the distance
                      between the electrodes plays a crucial role. This failure is
                      more likely with a lower distance, particularly when the SPE
                      is mechanically prone to shrinkage, for example at higher
                      temperatures as systematically revealed by mechanical
                      compression tests. Additionally, the active mass loading has
                      a crucial impact on short circuits, and thus the “voltage
                      noise” failure, as well. An effective and practically
                      simple solution to realize cell operation with a PEO-based
                      SPE is the incorporation of a spacer between the electrodes.
                      This modification prevents the detrimental shrinkage and
                      enables charge/discharge cycling performance in NMC622||Li
                      cells with a defined and constant electrode distance, thus
                      without voltage noise, and finally fulfills a reasonable
                      benchmark for systematic $R\&D$ with specific capacities
                      above 150 mA h g−1 even at 40 °C.},
