Research on Interface Control and Electrochemical Performance Optimization of High Stability Textile based Composite Electrode Materials

In response to the urgent demand for high stability, high conductivity, and long-life electrode materials in fields such as wearable electronics, flexible energy storage, and smart fabrics, textile based composite electrodes have become a research hotspot due to their advantages of flexibility, breathability, braiding, and low cost. However, the current textile based electrodes generally have bottlenecks such as weak interfacial bonding strength, easy breakage of conductive networks, easy detachment of active substances, poor cycling stability, and insufficient rate performance, which seriously restrict their practical applications. This article focuses on improving the long-term stability and electrochemical perfor mance of electrodes, and systematically conducts research on interface regulation and performance optimization of textile based composite electrodes. Construct a three in one structural model of “fiber substrate transition interface active layer” to reveal the intrinsic relationship between interface binding force, charge transfer, ion diffusion, and structural stability; Propose four types of interface control strategies: interface etching, interface bridging, interface cross-linking, and interface encapsulation, to achieve strong bonding between the substrate and functional layer. The stable textile electrode interface supports flexible energy storage and wearable sensing devices where electrical contact reliability is critical.
