Porous Perovskite LaNiO(3) Nanocubes as Cathode Catalysts for Li-O(2) Batteries with Low Charge Potential

Developing efficient catalyst for oxygen evolution reaction (OER) is essential for rechargeable Li-O(2) battery. In our present work, porous LaNiO(3) nanocubes were employed as electrocatalyst in Li-O(2) battery cell. The as-prepared battery showed excellent charging performance with significantly r...

description Developing efficient catalyst for oxygen evolution reaction (OER) is essential for rechargeable Li-O(2) battery. In our present work, porous LaNiO(3) nanocubes were employed as electrocatalyst in Li-O(2) 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 LaNiO(3) nanocubes ensured the Li-O(2) 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-O(2) battery. Our results indicated that porous LaNiO(3) nanocubes represent a promising cathode catalyst for Li-O(2) battery.
