Preparation of ferromagnetic perovskite La0.65Sr0.35MnO3 electrodes for supercapacitor applications

Ferromagnetic perovskite La0.65Sr035MnO3 (LSM) is prepared as an active material for electrodes with high active mass loading of 40 mg cm−2 for applications in supercapacitors. The experimental approach of this investigation is based on the use of high energy ball milling and application of gallocyanine as an advanced catecholate-type chelating dispersant. We report a high capacitance of 3.75 F cm−2 from cyclic voltammetry data at 2 mV s−1 and …
