Batteries are made of two electrodes involving different redox couples that are separated by an electronically insulating ion conducting medium, the electrolyte. The later might be a solid (inorganic or polymer ), despite conductivities being typically very low at room temperature (<0.1 mS/cm) or most commonly a liquid with a certain concentration of dissolved salt.
