      abstract     = {In searching for polymer-based electrolytes with improved
                      performance for lithium ion and lithium metal batteries, we
                      studied block copolymer electrolytes with high amounts of
                      bis(trifluoromethane)sulfonimide lithium obtained by
                      macromolecular co-assembly of a
                      poly(isoprene)-block-poly(styrene)-block-poly(ethylene
                      oxide) and the salt from tetrahydrofuran. Particularly, an
                      ultra-short poly(ethylene oxide) block of 2100 g mol−1
                      was applied, giving rise to 2D continuous lamellar
                      microstructures. The macroscopic stability was ensured with
                      major blocks from poly(isoprene) and poly(styrene), which
                      separated the ionic conductive PEO/salt lamellae. Thermal
                      annealing led to high ionic conductivities of
                      1.4 mS cm−1 at 20 °C with low activation energy and
                      a superior lithium ion transference number of 0.7,
                      accompanied by an improved mechanical stability (storage
                      modulus of up to 107 Pa). With high Li:O ratios >1, we
                      show a viable concept to achieve fast Li+ transport in block
                      copolymers (BCP), decoupled from slow polymer relaxation.},
