One of the important factors that hinders the widespread adoption of green technologies is the lack of environmentally friendly batteries. The electrochemical batteries are currently the best choice for storing electricity for most industrial needs and products. Unfortunately, the production of the metals needed to make the electrodes for electrochemical batteries is a serious environmental problem. Electrolytic capacitors that show high energy densities are acceptable to the industry, but they contain, in addition to metals, very harmful organic substances. Polymer and ceramic capacitors show very low energy density compared to the conventional batteries and therefore cannot be widely used for electricity disposal. At the same time, all other features of that capacitors that characterize battery systems are ideal. A brief comparison of the basic properties of electrochemical and physical batteries was presented. Some economic aspects were also described.
