      abstract     = {Dual-ion batteries (DIBs) represent a promising alternative
                      for lithium ion batteries (LIBs) for various niche
                      applications. DIBs with polymer-based active materials, here
                      poly(2,2,6,6-tetramethylpiperidinyl-N-oxyl methacrylate)
                      (PTMA), are of particular interest for high power
                      applications, though they require appropriate electrolyte
                      formulations. As the anion mobility plays a crucial role in
                      transport kinetics, Li salts are varied using the
                      well-dissociating solvent γ-butyrolactone (GBL). Lithium
                      difluoro(oxalate)borate (LiDFOB) and lithium
                      bis(oxalate)borate (LiBOB) improve cycle life in PTMA||Li
                      metal cells compared to other Li salts and a LiPF6- and
                      carbonate-based reference electrolyte, even at specific
                      currents of 1.0 A g−1 (≈10C), whereas LiDFOB reveals
                      a superior rate performance, i. e., $≈90 \%$ capacity
                      even at 5.0 A g−1 (≈50C). This is attributed to
                      faster charge-transfer/mass transport, enhanced
                      pseudo-capacitive contributions during the de-/insertion of
                      the anions into the PTMA electrode and to lower
                      overpotentials at the Li metal electrode.},
