Abstract

Three-dimensional (3D) supercapacitors consisting of Ba _0.65Sr_0.35TiO₃ (BST)/NiSi₂/silicon microchannel plate (MCP) stacked structure have been fabricated. The silicon MCP produced by electrochemical etching is utilized as a backbone of the 3D structure on which a nickel silicide current collector layer and Ba _0.65Sr_0.35TiO₃ dielectric layer are deposited successively by electroless plating and the sol-gel method, respectively. The morphology and structure of the 3D BST/NiSi₂/Si-MCP structure are characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) and the electrochemical properties are determined by cyclic voltammetry (CV) and chronopotentiometry. The structure exhibits excellent capacitive behavior with a maximum capacitance of 784 F g^-1. After 700 charging/discharging cycles, the C_f decreases slightly with only a 5.7% loss and is stable after more than 700 cycles. The BST/NiSi₂/Si-MCP 3D structure is a potential supercapacitor in industrial applications.
