초록/요약
Electrochromic energy storage systems (EESS) have emerged as promising candidates for next-generation multifunctional devices, enabling real-time visual monitoring of energy states alongside efficient energy storage. In this work, a rational morphological and porosity engineering strategy was employed to enhance both the electrochemical and electrochromic performance of polyaniline (PANi) electrodes. PANi architectures with distinct morphologies—rod, hollow, and porous—were synthesized, and their porosity was systematically tuned to optimize Zn2+ ion diffusion and electron transport kinetics. Among them, Porous exhibited superior charge transport properties, delivering a high specific capacity of 149.3 mAh g-1, outstanding coloration efficiency of 79.8 cm2 C-1, and excellent cycling stability with 97.3 % capacity retention over 1,400 cycles at 4 A g-1. This corresponds to a 27.7 % enhancement in performance compared to Rod. These results underscore the pivotal role of morphology and porosity modulation in advancing the functionality of organic electrode materials for electrochromic Zn-ion batteries, offering a compelling pathway toward the development of high-performance, multifunctional energy storage platforms.
