      abstract     = {The greatest challenges towards the worldwide success of
                      battery-powered electric vehicles revolve around the safety
                      and energy density of the battery. Single-ion conducting
                      polymer electrolytes address both challenges by replacing
                      the flammable and unstable liquid electrolytes and enabling
                      dendrite-free cycling of high-energy lithium metal anodes.
                      To date, however, their commercial use has been hindered by
                      insufficient ionic conductivities at ambient temperature
                      (commonly not exceeding 10−6 S cm−1) and the limited
                      electrochemical stability towards oxidation, in particular
                      when incorporating ether-type building blocks, limiting
                      their application to rather low-voltage cathode materials
                      like LiFePO4. Here, we introduce ether-free, nanostructured
                      multi-block copolymers as single-ion conducting
                      electrolytes, providing high thermal stability and
                      self-extinguishing properties and, if plasticized with
                      ethylene carbonate, ionic conductivities exceeding 10−3 S
                      cm−1 above 30 °C, i.e., approaching that of
                      state-of-the-art liquid electrolytes. Moreover, these
                      single-ion conducting ionomers present highly reversible
                      lithium cycling for more than 1000 h and, as a result of
                      their excellent electrochemical stability, highly stable
                      cycling of Li[Ni1/3Co1/3Mn1/3]O2 cathodes. To the best of
                      our knowledge, this is the first polymer electrolyte that
                      presents such remarkable ionic conductivity and outstanding
                      electrochemical stability towards both reduction and
                      oxidation, thus, paving the way for advanced high-energy
                      lithium metal batteries. Remarkably, the realization of
                      well-defined continuous ionic domains appears to be the key
                      to efficient charge transport through the electrolyte bulk
                      and across the electrode/electrolyte interface, highlighting
                      the importance of the self-assembling nanostructure. The
                      latter is achieved by carefully (i) designing the copolymer
                      structure, i.e., introducing alternating ionic blocks with a
                      very regular distribution of weakly coordinating anions
                      along the polymer chain and rigid blocks, which are
                      completely immiscible with ethylene carbonate, and (ii)
                      choosing the processing solvent, taking into account its
                      interaction with the different copolymer blocks.},
