Fluorine induced surface reconstruction of perovskite ferrite oxide as cathode catalyst for prolong-life Li-O2 battery

Stepping Up the Kinetics of Li–O2 Batteries by Shrinking Down the Li2O2 Granules through Concertedly Enhanced Catalytic Activity and Photoactivity of Se-Doped LaCoO3

“…In all these discharge curves, Se 3.28% -LCO showed a higher voltage plateau than both LCO and Super P, evidencing its high activity in lowering the ORR overpotential for Li 2 O 2 formation. We would like to further note that the high specific capacities delivered by Se 3.28% -LCO at all tested current densities from 100 to 1000 mA g –1 ranked among the best reported for perovskites in literature (Figure e, Figure S13, Table S2), offering a new benchmark for perovskite-based cathode catalysts in LOBs. ,,,,− …”

Applications of all-inorganic perovskites for energy storage

“…138 Hou et al demonstrated a surface reconstruction strategy on perovskite La 0.8 Fe 0.9 Co 0.1 O 3-δ (LFCO) to prepare a LaF 3 /LFCO composite, which induces a modified surface and also manipulates the electronic structure. 139 The optimized surface and electronic structure adjusted the discharge reaction pathway and formed thin petal-like F-doped Li 2 O 2 , which displays better conductivity and benefits Li–O 2 battery performance. Table 4 summarizes the electrochemical properties of the above-mentioned all-inorganic perovskite materials for Li–O 2 batteries.…”
