Abstract
An electrochemical energy storage cell includes a first electrically insulating substrate and a first electrical conductor layer extending on an area of the first electrically insulating substrate, a second electrically insulating substrate and a second electrical conductor layer extending on an area of the second electrically insulating substrate, a first electrode layer composed of positive electrode material, a second electrode layer composed of negative electrode material, a first separator layer, a stacked arrangement of the layers: the first electrically insulating substrate—the first electrical conductor layer—the first electrode layer—the first separator layer—the second electrode layer—the second electrical conductor layer—the second electrically insulating substrate, a first electrolyte enabling an ion flow between the electrode layers, an electrode region with the stacked arrangement of the electrode layers and a supercapacitor region, a second separator layer, a second electrolyte enabling an ion flow between the supercapacitor layers.
