What is it about?

In this study, supported noble metal catalysts Pt/C, Pd/C, and Au/C were paired with popular Li–O2 electrolyte solvents dimethoxyethane (DME), tetraglyme (TEGDME), and dimethyl sulfoxide (DMSO). The effects of these combinations on stability, kinetics, and activity were assessed.

Why is it important?

Careful selection of oxygen electrode materials and their morphology is necessary to promote cyclability while enabling higher charge rates.


The results presented here demonstrate that catalysts do affect oxygen reduction and evolution kinetics and activity, and that proper pairing with non-aqueous electrolytes is essential to realize those benefits.
