      abstract     = {Hyperbranched polymers comprised of polyrotaxanes as
                      mechanically stable backbone and grafted polycaprolactone
                      (PCL) side chains are utilized as solid polymer electrolyte
                      for application in lithium metal (LMBs) and lithium ion
                      batteries (LIBs). The polyrotaxanes were obtained from
                      self-assembly of Cyclodextrin (CD) host molecules threading
                      onto polyethylenoxide (PEO) chains. In particular, CD serves
                      as initiator for a ring-opening-polymerization of PCL
                      affording pendant side chains with merely a few monomer unit
                      lengths that foster enhanced lithium ion transport, as
                      mediated by well-defined lamellar morphology of the PCL side
                      chains. An impressive ionic conductivity of 1 mS cm−1
                      of the solid polymer electrolyte at 60 °C and more than
                      0.1 mS cm-1 at room temperature in addition to a
                      superior oxidative electrochemical stability of up to
                      4.7 V vs. Li/Li+ allows for robust galvanostatic cycling
                      in LiFePO4|Li cells, even at reduced temperatures not
                      accessible by commonly utilized PEO-based electrolytes. The
                      hyperbranched polymers can be readily up-scaled and further
                      modified, thereby demonstrating the versatility of the
                      introduced class of solid-state polymer electrolytes, as
                      reflected by its interfacial stability against the
                      high-capacity Lithium metal anode.},
