“…Due to the super electronic and ionic conductivity properties, La 0.85 Sr 0. 15 MnO 3 have been discussed as supercapacitor electrodes using the solegel method [2,[14][15][16][17]. However, the effect of the calcination temperature and time in the fabricating samples as electrode materials of supercapacitors is blurry [3,5,17,18].…”

Perovskite structural metal oxides as electrode materials present promising and potential properties due to excellent storage characteristics. Herein, series of perovskite type LaMnO 3 nanopowders were synthesized by the 'sol-gel' method with a heat treatment at different temperatures (700°C-900°C) for different times. The morphology characterization, structures and electrochemical performances were investigated. The preferable sample for electrochemical energy storage device can be obtained at 900°C with 2 h annealing. Furthermore, to improve the properties of the electrode materials, the samples were combined and rectified with reduced graphene oxide (rGO) and strontium (Sr), respectively. The results indicate that the rGO/Sr-doped LaMnO 3 oxide materials have excellent electrochemical properties. These findings are beneficial for the selection and preparation of electrode materials.

The structural, morphological, magnetic, and magnetocaloric properties of nanocrystalline Pr0.7La0.3MnO3 (PLMO), synthesized by using a wet chemical Sol-gel method, have been investigated. The single-phase nature of nanocrystalline PLMO with orthorhombic crystal structure along with the Pbnm space group was confirmed by Rietveld analysis of the X-ray diffraction pattern. The average crystallite size and lattice microstrain were determined using the Williamson-Hall technique, and they were found to be ~ 28 nm and ~ 0.00137, respectively. Transmission electron microscopy shows the particle size and structural characteristics of the sample. Temperature-dependent magnetization data show paramagnetic to ferromagnetic transition. According to Banerjee criterion, the positive slope of Arrott's plot for nanocrystalline PLMO indicates the second-order magnetic phase transition. In a 5 T external magnetic field, the maximum magnetic entropy change (∆SM) was found to be 2.47 J/kg K. The refrigerant capacity and relative cooling power were calculated and the values are 193.3 and 277.57 J/kg, respectively, under a 5 T applied external magnetic field.
