According to the United Nations projections of population growth, the world population of humans will reach 13 billion at the end of the XXIst century. The population growth consequently leads to increased demand for electrical energy, which results in greater interest in renewable energy sources. Unfortunately, in this case, conversion of the energy strongly depends on weather conditions and less on the human activity. This applies in particular to the solar and wind power plants. The accumulation of energy by conversion of electrical energy to chemical energy is one way to reverse this unfavourable situation. Such conversion allows to store the energy surplus and to utilize it in the energy deficit period. Production and development of existing energy storage devices is necessary to move away from conventional energy sources to renewable ones. The dynamic development of technology and construction of electrochemical capacitors (ECs), mostly driven by the needs of the automotive industry, leads to the conclusion that ECs are becoming a more viable alternative to traditional batteries. This is connected primarily with their ability to quickly charge and discharge, many times higher durability, maintenance-free operation and environment-friendly materials used for their production.
