Description
Summary:Self‐healing and flexibility are significant for many emerging applications of secondary batteries, which have attracted broad attention. Herein, a self‐healing flexible quasi‐solid Zn‐ion battery composing of flexible all‐in‐one cathode (VS2 nanosheets growing on carbon cloth) and anode (electrochemically deposited Zn nanowires), and a self‐healing hydrogel electrolyte, is presented. The free‐standing all‐in‐one electrodes enable a high capacity and robust structure during flexible transformation of the battery, and the hydrogel electrolyte possesses a good self‐healing performance. The presented battery remains as a high retention potential even after healing from being cut into six pieces. When bending at 60°, 90°, and 180°, the battery capacities remain 124, 125, and 114 mAh g−1, respectively, cycling at a current density of 50 mA g−1. Moreover, after cutting and healing twice, the battery still delivers a stable capacity, indicating a potential use of self‐healing and wearable electronics. A self‐healing flexible quasi‐solid Zn‐ion battery composes of all‐in‐one cathode and anode, and a self‐healing hydrogel electrolyte. The free‐standing all‐in‐one electrodes enable a high capacity and flexible transformation of the battery, while the hydrogel electrolyte possesses a self‐healing performance. Under bending at different angles, and cutting/healing many times, the batteries remain very stable, indicating a promising potential for broad applications.
