Coin cell Supercapacitors Based on CVD Grown & Vertically Aligned Carbon Nanofibers
May 12 , 2021
A schematic diagram of the assembly (Figure 1) shows the components of the coin-cell (20 mm diameter and 3.2 mm thickness) SCs. Three SS, 18Cr9Ni from RECORD, discs pairs were used for VACNFs growth which also worked as current collectors. The diameter and thickness of the discs in the pair was different. A standard coin cell disc punching machine (Xiamen Tmaxcn Inc.)1 mm thick and 16 mm diameter ...
