This method may be used to make both symmetric and asymmetric ultracapacitors.

Various supercapacitor structures are provided, including one supercapacitor structure with a shared C-shaped current collector, and another supercapacitor structure with stacked supercapacitors.

Supercapacitor structures are provided which include, for example: one or more layers of supercapacitors; and one or more contact tabs.

The 5.5V supercapacitors sold in the market are in reality composed of two supercapacitors connected in series.

Supercapacitors have a voltage between 2.5V and 3V and until 3.8V for hybrid supercapacitors.

Will Super Capacitors eventually replace batteries?

The 5.5V supercapacitors sold in the market are in reality composed of two supercapacitors connected in series.

If an ultracapacitor bank is used for storage, the charged ultracapacitor bank can be used as a backup or auxiliary power source for mining operations.

The power supply comprises a voltage source (303), two or more supercapacitors (305, 307), and switches (51, 52, 53, 54, 55) between the voltage source and the two or more supercapacitors.

Here is a list of scientific publications on supercapacitors or to related topics:

The energy storage unit (11) used therefore exclusively contains capacitors in the form of super capacitors (13) or a combination of super capacitors (13) and electrochemically acting accumulators (14) as the storage medium.

Supercapacitors: principles and characterization using Autolab

The short term energy storage includes a plurality of super capacitors being connected in series.

The invention is useful for making electrochemical generators, high load capacitors or elctrochrome systems.

Also disclosed are related methods for fabricating such supercapacitors.
