Advantages to Super Capacitors:
1. Can be used and recharged millions of time.
2. Low impedance - enhances load handling when put in paralleled
with a battery.
( I think this means a flashlight could be designed to run
longer with less batteries )
3. Re-charge in seconds.
4. Simple charge methods - no full-charge detection is needed; no
danger of overcharge.
( thus easier to charge in cigarette lighter, Right ? )
Limitations to Super Capacitors:
1. Linear discharge voltage prevents use of the full energy spectrum.
( I think this means LED light goes out immediately, instead of
running dim for several hours )
2. Low energy density - typically holds one-fifth to one-tenth the
energy of an electrochemical battery.
( thus more bulky than a AA battery )
3. Cells have low voltages - serial connections are needed to
obtain higher voltages. Voltage balancing is required if more than
three capacitors are connected in series. ( I think this means
more of a problem with brighter LED lamps )
4. High self-discharge - the rate is considerably higher than that
of an electrochemical battery.
( thus not good for expedition trips underground )
