abstract = {To go beyond polyethylene oxide in lithium metal batteries,
a hybrid polymer/oligomer cell design is presented, where an
ester oligomer provides high ionic conductivity of 0.2 mS
cm−1 at 40 °C within thicker composite cathodes with
active mass loadings of up to 11 mg cm−2 (LiNbO3-coated)
LiNi0.6Mn0.2Co0.2 (NMC622), while a 30 µm thin
scaffold-supported polymer electrolyte affords mechanical
stability. Corresponding discharge capacities of the hybrid
cells exceed 170 mAh g−1 (11 mg cm−2) or 160 mAh g−1
(6 mg cm−2) at rates of either 0.1 or 0.25 C. Multilayer
pouch cells are projected to enable energy densities of 235
Wh L−1 (6 mg cm−2) and even up to 356 Wh L−1 (11 mg
cm−2), clearly superior to other reported polymer-based
cell designs. Polyester electrolytes are environmentally
benign and safer compared to common liquid electrolytes,
while the straightforward synthesis and affordability of
precursors render hybrid polyester electrolytes suitable
candidates for future application in solid-state lithium
metal batteries.},
