Diamond-coated Carbon-based Flexible SC-Battery Hybrids with High Energy and Power Density
With increasing energy demands and reliance on external sources for batteries, there is an urgent need for advanced energy storage solutions, especially for flexible electronics. Traditional batteries offer high energy densities but suffer from low power output, whereas supercapacitors (SCs) provide high power densities yet lack sufficient energy storage. To address this, a flexible SC-battery hybrid design is proposed, which will utilise carbon-based materials coated with a boron-doped diamond coating via chemical vapor deposition. This hybrid electrode design combines the energy storage of batteries with the rapid discharge capabilities of SCs, achieving high gravimetric and volumetric energy and power densities. Even under significant bending, these flexible hybrids are expected to maintain stable performance, making them promising candidates for next-generation portable and flexible electronic devices.
