title: Porous perovskite LaNiO3 nanocubes as cathode catalysts for Li-O2 batteries with low charge potential.
abstract: Developing efficient catalyst for oxygen evolution reaction (OER) is essential for rechargeable Li-O2 battery. In our present work, porous LaNiO3 nanocubes were employed as electrocatalyst in Li-O2 battery cell. The as-prepared battery showed excellent charging performance with significantly reduced overpotential (3.40 V). The synergistic effect of porous structure, large specific surface area and high electrocatalytic activity of porous LaNiO3 nanocubes ensured the Li-O2 battery with enchanced capacity and good cycle stability. Furthermore, it was found that the lithium anode corrosion and cathode passivation were responsible for the capacity fading of Li-O2 battery. Our results indicated that porous LaNiO3 nanocubes represent a promising cathode catalyst for Li-O2 battery.
