Hierarchical layer to layer of ternary heterostructure: Nanograin nickel carbonate embedded layered NiMnO 3 ‐rGO‐Co 3 O 4 composite array as a high‐performance electrode for hybrid supercapacitors

“…The XRD pattern of Ni‐NMO NFAs afforded peaks at 33.8°, 36.6°, 39.7°, and 41.8° 2 θ corresponding to the (211), (110), (222), and (210) planes, respectively, which matched that of the rhombohedral phase NiMnO 3 (JCPDS card No 75‐2089) 24 . The crystal structure of the NiMnO 3 is constructed through the MnO 6 and NiO 6 octahedrons 44 . The additional peaks at 33.1°, 36.6°, 39.7°, and 43.3° 2 θ corresponding to the (104), (006), (110), and (113) planes correspond to the rhombohedral phase NiCO 3 (JCPDS card No 78‐0210).…”

The Ni-NMO-rGO pattern displayed the characteristics of NiMnO 3 -NiCO 3 composition without any significant peaks at approximately 26.1 2θ, which may represent the presence of the rGO layer.…”

Applications of all-inorganic perovskites for energy storage

“…Zhang et al synthesized a cathode material with perovskite structure of bimetallic oxides (NiMnO 3 ) for ZIBs, which exhibited a high capacity of 300 mA g À1 at a current density of 280 mA h g À1 and an excellent cycling capability of 120 mA h g À1 even after 10 000 cycles at high current density. 119 Manganese-based cathodes are usually affected by manganese leaching and structural deformation, resulting in a continuous capacity decay during cycling. The by-products generated during the long cycling period will be deposited on the surface of the cathode materials, such as ZnO, Mn 3 O 4 , Zn(OH) 2 , and Mn(OH) 2 , which seriously affect the cycling life.…”

Graphene Oxide Wrapped ZnMnO3 Nanorod as Advanced Cathode for Aqueous Zinc‐Ion Batteries

“…[ 18 ] However, it is reported that the strong electrostatic interaction between spinel lattices may limit the further enhancement of the electrochemical performance. [ 16 ] The symmetrical structured oxides like ZnMnO 3 , CaMnO 3 , and LaMO 3 (M = Fe, Co, Ni) are widely applied in sodium‐ion batteries and LIBs; [ 19–21 ] among them, the cubic structured ZnMnO 3 (ZMO) nanotube arrays deliver superior cycle stability (857.5 mAh g −1 after 200 cycles at 500 mA g −1 ) in LIBs. It is reasonable that the ZnMnO 3 may be a suitable cathode for ZIBs.…”
