Supercapacitors
Also known as double-layer electrolytic capacitors, supercapacitors are devices that
permit the storage of large amounts of energy, thousands of times greater than traditional capacitors.
Its many advantages include:
- High power capacity: they allow very
high intensity charging and discharging
without the premature degradation or deterioration of the battery. It can be charged
in a matter of seconds.
- Very long life: the electronic components are highly durable. They can perform millions of charge and discharge cycles if kept in suitable work temperature
conditions.
- Simple charging process: they do not
require a specific charging curve and there
is no risk of overcharging, unlike lead-acid
batteries.
- Safety: there is no possibility of erosion
or combustion due to supercapacitator
overload or over-discharge.
- They are maintenance-free.
- Excellent performance at low temperatures: supercapacitors suffer minimal performance loss and do not degrade
when working at low temperatures; in fact,
the opposite happens, as its operating life is
extended.
However, they have certain limitations:
- Low specific energy: supercapacitors
can store a significant amount of energy, although not as much as traditional batteries
of the same size and weight.
- Moderate self-discharge rate: they experience a greater spontaneous discharge
process of electrical energy.
- High cost per watt-hour: the initial cost
of supercapacitors is higher than traditional
batteries. However, this cost is offset by its
durability.
