Direct tracking of solid polymer electrolyte (SPE) decomposition in comparison to a liquid analogue was accomplished by monitoring the evolution volatile species using online electrochemical mass spectrometry (OEMS). Reduction poly(trimethylene carbonate)-based SPE dominated CO2 formation. Detection and an absence CO confirms preferred reduction degradation pathway involving C−O bond cleavage a...

The inherent skeletal and thermal features to forge polymers by step-growth polymerization are conflicting with any depolymerization strategies via cascade back-biting reactions that necessitate adequate ceiling temperature, spacers, functionalities create cyclic compounds. Here, we report the edition of poly(carbonate-urea)s poly(carbonate-amide)s depolymerized on demand into their native prec...

The polymer binder is a key constituent of silicon-based electrode formulation for lithium-ion batteries. However, its extremely difficult visualization in fresh electrodes becomes completely impossible cycled electrodes. Here, the combination scanning transmission electron microscopy—valence energy-loss spectroscopy with use specific electrolyte solvent composition (a mixture dimethyl carbonat...
