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. So not only is …
Lithium-based batteries have limited lifetime cycles due to parasitic reactions that occur every time the battery is discharged and recharged. If kept in a 100% charged state, this parasitic reaction increases, further decaying the battery life. Super capacitors achieve 100X the cycle life of a lithium battery because there is no such reaction in the capacitor …

On the other side, supercapacitors are used in applications which are not so far suitable for these devices.

Adding a diode will create a 0.7V voltage drop (for a typical silicon diode) at the router, so instead of 4.5V the power supply is putting out, the router will only see 4.5-0.7=3.8V at the router, which would be within the range of a Lithium battery voltage range (Lithium batteries have voltages ranging 3.3 - 4.2V).
Batteries have a slower charge and discharge relative to supercapacitors and supercapacitors cannot discharge for nearly as long as batteries.

Batteries, EDLC and LICs each have different strengths and weaknesses, making them useful for different categories of applications. Energy storage devices are characterized by three main criteria: power density (in W/kg), energy density (in W⋅h/kg) and cycle life (no. of charge cycles). LIC''s have higher power densities than batteries, and are safer than lithium-ion batteries
Unfortunately, however, supercapacitors still have two main problems that remain since their inception: they can store 10-50 times less energy per kilo/liter than batteries (i.e. they are very bulky) and they are very expensive. As a result, the supercap industry has never really been thriving. Then li-ion came into the picture. Thanks to the ...
