Stretchable Transparent Microsupercapacitor from Nanodiamond Decorated Laser-Induced Graphene: Design and Demonstrator

As global energy demands escalate, traditional storage methods face limitations in capacity, efficiency, and scalability. Supercapacitors offer a promising solution with high power density and rapid charge-discharge cycles, especially when miniaturized for portable electronics and wearables. Our MSCA project addresses this demand by fabricating compact and high-performance supercapacitors and batteries. These innovations are crucial for modern society, particularly in powering portable electronics and wearables like health monitoring sensors. The project aims to optimize materials and device architectures to enhance energy storage capabilities and ensure reliability under bending and twisting conditions. Ultimately, the goal is to enable practical applications in charging portable electronic devices and health monitoring, advancing energy-efficient solutions for interconnected systems.

Project objective

Stretchable microsupercapacitors (MSCs) can operate in multiple mechanical distortions including stretching, bending, twisting, and compression. These mechanical adaptabilities are essential for powering wearable electronics and implantable biomedical devices. Recent progress in the stretchable supercapacitor field primarily emphasizes on the electrode materials and their design concept. In the search of outstanding electrode material, we have seen consumer-grade carbon-based MSC electrodes would be benefitted from a thin layer of diamond (sp3-hybridized carbon) coating as diamond possesses wide electrochemical (EC) potential window, a low and stable background current, and exceptional stability in a wide range of corrosive media. However, most of the growth techniques like chemical vapor deposition and atomic layer deposition support the diamond deposition on any solid hard substrate (such as Si, Mo, Ta, etc.), and also the gas phase growth temperature is too high to deposit diamond on any flexible substrate. On the other hand, recently, large scale, facile and one-step process for the production of flexible graphene-based porous nanomaterial called laser-induced graphene (LIG) has been investigated worldwide and regarded as a suitable platform to build EC energy storage devices. Therefore, we believe that in situ bonding between the flexible porous graphene networks with nanocrystalline diamond using a single-step lasing process, can provide a major breakthrough in the field of flexible wearable and portable electronic device technology. To utilize the dual advantage of both sp2 and sp3 bonded carbon, herein, we propose a simple strategy to synthesize nanostructured carbon hybrid where conductive nanodiamonds will be decorated between the flexible three-dimensional porous network of sp2 carbon (LIG). In the application scenario, the carbon hybrid then transferred to a transparent and stretchable silicone rubber substrate to obtain all-solid-state planar MSCs.
