With the increasing use of renewable energy sources, such as photovoltaic panels and wind turbines, there is growing interest in new ways of collecting and storing electricity. Typical solutions in this area are lithium-ion or lead-acid batteries. The main shortcomings of these examples are: limited durability, toxicity of appropriate electrolytes and components, potential fire hazard, disposal problems of waste batteries. The new high quality component that has appeared on the market is a battery called Aqueous Hybrid Ion battery containing salt electrolyte - neutral to the environment. For a detailed description of AHI battery technology, see [1]. The materials used in the construction do not contain heavy metals and are fully recyclable as opposed to existing leadacid, nickel-cadmium, nickel-metal hydride, sodium-sulfur, and lithium-ion batteries [2]. This component also does not present a fire hazard. In addition, the AHI battery ensures significant durability expressed by a large number of charging and discharging cycles. Due to the aforementioned advantages it is suitable for the construction of scalable storage, in particular for stationary applications. However, the disadvantage of this type of battery is the relatively large internal resistance, which complicates the assembly of a structure suited for large, pulsed charging and discharging currents. In such cases the solution may be to use an additional component in the form of a supercapacitor. This problem is the subject of many studies [3], [4], [5], [7], which point out the possibility of improving the dynamic parameters and extending the battery life. The following sections show how to create the AHI battery model and the supercapacitor model as components of the hybrid system. An example hybrid storage system, made up of AHI type S30-0080 batteries and LSUM 129R6C 0062F EA supercapacitor, was established and used for the validation of the elaborated model. [...]
