Abstract: An electrode and a galvanic cell are provided, each having a shaped body which is composed of porous carbon foam and in the pores of which layers of active material and electrolyte, in particular solid-state electrolytes, are formed. The layer including electrochemical active material is in this case in electrically conductive contact with the shaped body, and the layer including solid-state electrolyte material is in contact with the active material. The electrodes or galvanic cells are particularly suitable for use in electrical energy stores for vehicles, such as in batteries for example, for delivering electrical energy to traction motors of motor vehicles with an electric or hybrid drive and are distinguished in that particularly high energy and power densities of corresponding galvanic cells and batteries manufactured therefrom are possible with them.

Abstract: A cathode in a state prior to a first charging process is provided having an active cathode material and lithium peroxide. A lithium ion battery or an electrochemical cell includes the same cathode. A method is also provided for forming a lithium ion battery, and a lithium ion battery is provided which includes a cathode having an active cathode material, a separator, an anode having an active anode material, and an electrolyte, wherein after a formed cell is fully discharged, the active cathode material holds the same lithium content as before the formation process.
