TL;DR: In this article, the authors show that the kinetics of oxygen reduction reaction are influenced by catalysts at small discharge capacities, but not at large Li2O2 thicknesses, yielding insights into the governing processes during discharge.

TL;DR: In this paper, hollow carbon fibers with diameters on the order of 30 nm were grown on a ceramic porous substrate, which was used as the oxygen electrode in Li-O2 batteries.

TL;DR: In this article, two characteristic Li2O2 morphologies are formed in carbon nanotube (CNT) electrodes in a 1,2-dimethoxyethane (DME) electrolyte: discs/toroids (50-200 nm) at low rates/overpotentials (10 mA gC−1 or E > 2.7 V vs. Li), or small particles (<20 nm), while discs exhibit a sloping profile with low overpotential (<4 V).

TL;DR: In this article, the authors report considerable chemical and morphological changes of reaction products in binder-free, vertically aligned carbon nanotube (VACNT) electrodes during Li-O2 battery cycling with a 1,2-dimethoxyethane (DME)-based electrolyte.

TL;DR: This work shows that the coalescence of two or more droplets on ultra-low adhesion surfaces leads to droplet jumping, and clarify the role of internal fluid dynamics during the jumping droplet coalescence process and underpin the development of systems that can harness jumping droplets for a wide range of applications.
