Because SCs electrochemical performances are mostly measured in specific values (i.e. specific capacitance, energy density, power density) which are either mass-balanced or volume or area-balanced. So, I think different amounts of material don't play any significant effect on specific capacitance.
Aditya Sharma The exact quantity of the electrode material depends on desired performance characteristics. Using a smaller amount (like 0.5 mg) costs less and can make things lighter, but it might not hold as much energy. If you use more (like 1 or 2 mg), it can hold more energy and work better, but it might cost more and have some limitations. Less amount (0.5 mg) is good for quick bursts of power, while more (1-2 mg) is better for storing more energy over time.
