abstract = {Li+-conducting solid polymer electrolytes (SPEs) obtained
from supramolecular self-assembly of trimethylated
cyclodextrin (TMCD), poly(ethylene oxide) (PEO), and lithium
salt are investigated for application in lithium-metal
batteries (LMBs) and lithium-ion batteries (LIBs). The
considered electrolytes comprise nanochannels for fast
lithium-ion transport formed by CD threaded on PEO chains.
It is demonstrated that tailored modification of CD
beneficially influences the structure and transport
properties of solid polymer electrolytes, thereby enabling
their application in LMBs. Molecular dynamics (MD)
simulation and experimental data reveal that modification of
CDs shifts the steady state between lithium ions inside and
outside the channels, in this way improving the achievable
ionic conductivity. Notably, the designed SPEs facilitated
galvanostatic cycling in LMBs at fast charging and
discharging rates for more than 200 cycles and high
Coulombic efficiency.},
