“…The perovskite-type LMO stores energy through the oxygen-vacancy tailored redox pseudocapacitance, and the ion diffusion along the oxygen octahedral edges confirms the high diffusion rate and full utilization of the internal structure [44]. In addition, MnO has also been reported as a negative electrode material with good properties.…”

La-based perovskite-type oxide is a new type of supercapacitor electrode material with great potential. In the present study, LaMnO3/MnO (LMO/MnO) nano-arrays supported by carbon cloth are prepared via a simple one-step electrodeposition as flexible supercapacitor electrodes. The structure, deposit morphology of LMO/MnO, and the corresponding electrochemical properties have been investigated in detail. Carbon cloth-supported LMO/MnO electrode exhibits a specific capacitance of 260 F·g−1 at a current density of 0.5 A·g−1 in 0.5 M Na2SO4 aqueous electrolyte solution. The cooperative effects of LMO and MnO, as well as the uniform nano-array morphology contribute to the good electrochemical performance. In addition, a symmetric supercapacitor with a wide voltage window of 2 V is fabricated, showing a high energy density of 28.15 Wh·kg−1 at a power density of 745 W·kg−1. The specific capacitance drops to 65% retention after the first 500 cycles due to the element leaching effect and partial flaking of LMO/MnO, yet remains stable until 5000 cycles. It is the first time that La-based perovskite has been exploited for flexible supercapacitor applications, and further optimization is expected.

“…A well-known procedure to increase the electronic conduction (or decrease the resistance) of composite-based on LaBO 3 perovskites is through the completely/or partial incorporation of diverse cations (Ca 2+ , Sr 2+ etc.) for La 3+ species on A-site, leading to a larger number of oxygen vacancies are inserted in the structure (Nan et al 2019;Ma et al 2020). For LaMnO 3 perovskite, the charge imbalance after the substitution is partially offset through the oxidation of Mn 3+ species (d 4 ) to Mn 4+ oxide species (d 3 ) in the B-site, jointly with the Jahn-Teller effect of manganese (Mn 3+ ) ion species, attending to the perovskite structure deformation (Louca et al 1997).…”

“…Hence, this pathway leading the electric conduction and O 2− dispersion rate of perovskites will likewise be improved because of O vacancy . A suited amount of cations substituting in the tetrahedral site could achieve perovskites with enhancing the perovskites capacity display (Nan et al 2019).…”

“…These nanomaterials are greatly influenced by valence state of B-site element, surface area and internal resistance. More importantly, research on energy and power densities of perovskite oxides are scanty (Nan et al 2019;Ding et al 2017). Design of La-based perovskite with high density, wide voltage window and high energy capacity for a flexible supercapacitor application was reported in the literature (Ma et al 2019a).…”

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.
