- •
Novel NiO/LaNiO3 film electrode with binder-free was prepared by spin-coating technique.
- •
The NiO/LaNiO3 electrode with appropriate LNO content exhibited a high specific capacitance of 2030 F/g at 0.5A/g and superior cycling stability (83％ retention of the initial capacitance after 1000 cycles) in 2 M KOH aqueous solution.
- •
The NiO is directly anchored on the Pt/Ti/SiO2/Si(100) substratewith binder-free, which is favorable for obtaining a larger specific surface.
