Can a symmetric supercapacitor be used in a super capacitor?

The resulting electrode had a specific capacitance of nearly 375 F g −1 at a current density of 0.5 A g −1. Moreover, the symmetric supercapacitor had a high capacity retention of approximately 95% after 10,000 charge/discharge cycles. Hence, the proposed electrode material shows promise in its potential application in supercapacitors.

What are the best EV supercapacitors?
