Summary: A series of LaCo1-xZnxO3 perovskite-type oxides (0 <= x <= 0.1) were successfully synthesized via the sol-gel process. The zinc doping significantly improved the electrochemical properties of LaCoO3, with LaCo0.95Zn0.05O3 demonstrating a four-fold increase in specific capacitance compared to the undoped electrode. A hybrid supercapacitor combining LaCo0.95Zn0.05O3 with activated carbon achieved a high energy density of 36.12 Wh.kg-1 and a capacitance retention of 81% after 5000 charge-discharge cycles at 5 A/g.

Summary: In this study, ZnO/NiO@NC electrode material was prepared using polyvinylpyrrolidone (PVP) as a structural guide and carbon source, and annealed under an N2 atmosphere to obtain an oxygen-vacancy-rich ZnO/NiO@N-doped carbon shell (ZnO/NiO@NC). The ZnO/NiO@NC electrode exhibited the highest specific capacitance (860.00 F/g), longer charge/discharge time, and lower impedance compared to other materials at a current density of 0.5 A/g. The excellent electrochemical performance can be attributed to the formation of an effective p-n heterostructure, surface oxygen vacancies, and a rich mesoporous structure, as well as the excellent electrical conductivity of the N-doped carbon shell.

Summary: Effective control over the manufacturing process of Ov-Co3O4@PPy, which consists of Co3O4 with rich oxygen vacancy defects and polypyrrole coating, enhances the capacitive and cyclic properties of the material. The specific capacitance of Ov-Co3O4@PPy is three times higher than that of Co3O4 without reduction treatment and unwrapped PPy. Moreover, the Ov-Co3O4@PPy//AC asymmetric supercapacitor exhibits a high specific energy density of 74.55 Wh kg(-1) and a capacitance retention rate close to 110% after 10,000 cycles.

Summary: The performance of optimization layered double hydroxide (LDH) electrodes via oxygen vacancy engineering is of great significance for high-performance hybrid supercapacitors. The addition of oxygen vacancy does not affect the original unique layered structure and creates more active centers, promoting faster electron transfer and ion conversion. The as-assembled Ov-CuCoLDH electrode shows an outstanding specific capacity of 1392.4 F g-1 and high degree of stability.
