Abstract

Abstract

The performance instability and degradation of flexible and stretchable in-plane micro-supercapacitors (FS-MSCs) under large deformation have limited their applications. Selecting suitable flexible electrode materials and integrating them with stretchable substrates is crucial to solve the problem, while it remains a challenge to simplify the device preparation and optimize performance. Here, we report a programmable single-wavelength laser processing strategy that simultaneously reduces/patterns reduced graphene oxide (RGO) interdigital electrodes and textures an elastomeric substrate. By pre-stretching the substrate and fitting it to the flexible RGO electrodes, our device demonstrates excellent performance robustness. A bending angle of over 300° and a tensile strain of about 120% of its original length can be withstood. Furthermore, by optimizing the substrate surface morphology with ordered gridding, the electrochemical properties and stability of the device have been significantly improved, which achieves a maximum capacitance of 1.34 mF/cm² with a fluctuation of only 1.5% under different tensile conditions. Even as the current density increases from 0.01 to 0.05 mA/cm² gradually, the specific capacitance fluctuation of the devices remains <7.4% under varying tensile strengths. Our work offers an effective solution for enhancing performance stability of in-plane FS-MSCs in harsh deformation environments, holding great potential for their future applications in wearable and portable energy storage.
