High-performance 2.6 V aqueous symmetric supercapacitor based on porous boron-doped diamond via regrowth of diamond nanoparticles

Having a wider potential window and higher stability than other traditional sp2-based carbon electrodes, heavily boron-doped diamond (BDD) electrode with three-dimensional porous nanostructure can considerably enhance the specific capacitance, making it one of the most promising electrode materials. In the work, we present a simple and reproducible method to create such a porous BDD film by using self-assembly seeding approach and microwave...
