摘      要：Supercapacitor diode is a novel ion device that performs both supercapacitor energy storage and ion diode rectification ***,previously reported devices are limited by their large size and complex *** this work,we demonstrate a screen-printed micro supercapacitor diode(MCAPode)that based on the insertion of a finger mode with spinel ZnCo_(2)O_(4) 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 ratioⅠof 11.99 at 40 mV s^(-1)).Taking advantage of the ionic gel electrolyte,which provides excellent stability during repeated flexing and at high *** addition,MCAPode exhibits excellent electrochemical performance and rectification capability inANDandORlogic *** findings provide practical solutions for future expansion of micro supercapacitor diode applications.
