Abstract: An electrical synchronous machine is provided for a rail-free vehicle. The vehicle has drive wheels and the synchronous machine is designed to generate a torque, which propels the vehicle, at the drive wheels. The synchronous machine has a stator and a rotor which rotates around the stator, wherein the stator has a stator winding of at least three-phase construction for forming a rotating stator magnetic field, and wherein the rotor has at least one rotor winding which is designed for forming a rotor magnetic field. A method for at least partially circumferentially establishing a current-excited synchronous machine provides a rotor yoke, provides a large number of rotor poles, fastens the rotor poles to the rotor yoke for forming a rotor, provides a stator, and inserts the stator into the rotor.

Abstract: A method produces an electrochemical cell for a solid-state battery having a negative electrode, a positive electrode and a lithium-ion-conducting solid electrolyte arranged between the negative electrode and the positive electrode. The negative electrode has a layer of metallic lithium which directly adjoins the solid electrolyte. In order to produce the electrochemical cell, the layer of metallic lithium is heated until it softens before being joined together with the solid electrolyte. An electrochemical cell includes the negative electrode with a layer of metallic lithium which directly adjoins the solid electrolyte, and a layer of a lithium-metal alloy on the layer of metallic lithium.

Abstract: A composite electrode is provided having a collector, the collector is coated with an electrode composition containing an active electrode material, a binding agent, and a conductivity additive such as conductive carbon black. The electrode composition has a concentration gradient along the direction of the electrode thickness in respect of the active electrode material and the conductivity additive, with the concentration gradient of the active electrode material increasing toward the collector, and the concentration gradient of the conductivity additive and the binder decreasing toward the collector. Two different methods of producing the composite electrode are also provided. A lithium-ion battery is further provided which includes a composite electrode having a collector, the collector is coated with an electrode composition containing an active electrode material, a binding agent, and a conductivity additive.
