Abstract

En 中文
Supercapacitor diode is a novel ion device that performs both supercapacitor energy storage and ion diode rectification functions. However, previously reported devices are limited by their large size and complex processes. In this work, we demonstrate a screen-printed micro supercapacitor diode (MCAPode) that based on the insertion of a finger mode with spinel ZnCo2O4 as cathode and activated carbon as anode for the first time, and featuring an excellent area specific capacitance (1.21 mF cm_2 at 10 mV s_1) and high rectification characteristics (rectification ratio I of 11.99 at 40 mV s_1). Taking advantage of the ionic gel electrolyte, which provides excellent stability during repeated flexing and at high temperatures. In addition, MCAPode exhibits excellent electrochemical performance and rectification capability in AND and OR logic gates. These findings provide practical solutions for future expansion of micro supercapacitor diode applications.
