Abstract

Electrochromic energy storage devices have both electrochromic and energy storage functions

and can indicate the energy storage status through real-time color changes. They have attracted attention in the fields of energy-efficient buildings and intelligent electronics. Polyaniline (PANI) has rich color changes and a high theoretical specific capacitance

and occupies a place in the fields of electrochromism and energy storage. In this study

in order to improve the capacitance of polyaniline

reactive blue 19 (RB19) with redox activity was add

ed when the polyaniline film was prepared via galvanostatic method

and polyaniline was doped by electrostatic interaction. The effects of the ratio of aniline to reactive blue 19 and the deposition time on the morphology and electrochemical performance of the polyaniline film were analyzed. The electrochromic energy storage device was assembled using indium-tin oxide (ITO) conductive glass with polyaniline film as the working electrode

ZnCl

as the electrolyte

and zinc flake as the counter electrode

and the performance was studied. The results show that the doping of reactive blue 19 greatly enhances the capacitance of polyaniline film. At a scan rate of 50 mV/s

the capacitance (

) of PANI-RB19

100:1(20min)

can reach 3.29 times that of PANI

(20min)

. At a current density of 0.1 mA·cm

−2

an area capacitance (

) of 32.41 mF·cm

−2

can be obtained

and a ten fold increase in current density results in a capacitance retention rate of 78.06%. The electrochromic energy storage device can generate 56.22% spectral modulation amplitude at 750 nm

and connecting the two devices in series can light up a red LED lights more than 3 h.
