Batteries vs. Supercapacitors? The Answer is Both.
The lithium ion battery will support that load until it''s almost completely discharged; a bigger concern is discharging the battery so far that it destroys the battery. The ultracap, however, will drop from 3V to 2V and still have almost half the total charged energy still in the capacitor, unavailable to us because of the drop-out voltage of the phone.
The choice between a battery and a capacitor will depend on the specific application and the requirements for energy density, power density, cycle life, size, weight, and voltage. Batteries are generally better suited for applications that require more energy and longer cycle life, while capacitors are better suited for high-power applications that …
