Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The DDA-Cu framework resists electrolyte dissolution and maintains useful conductivity, enabling stable LIB cycling and lean-electrolyte operation.
Caveat: Highest-loading lean-electrolyte data are described as preliminary by the authors.

High-density Cu-O3N redox-active centres provide reversible Li-ion storage through Cu2+/Cu+ and ligand-centred redox reactions.
Caveat: Mechanism is supported by ex situ spectroscopy and DFT rather than operando structural refinement.

Extended pi-d conjugation in Cu-O3N coordination ribbons facilitates charge transfer and gives high electronic conductivity.
Caveat: Conductivity value differs between main text/Figure S13 and SI Table S1, but both are approximately 10^-4 S cm^-1.
