A composite cathode is provided which includes a collector, an active cathode material, a binder, a solid inorganic lithium-ion conductor and a liquid electrolyte. The solid inorganic lithium ion conductor is present in the composite cathode in a higher volume and weight proportion than the liquid electrolyte. A method for forming the composite cathode is also provided, and a lithium ion battery is provided which includes a composite cathode having a collector, an active cathode material, a binder, a solid inorganic lithium ion conductor and a liquid electrolyte.

Composite cathode and lithium-ion battery comprising same, and method for producing said composite cathode

A galvanic element is provided having a solid-state cell stack containing a multiplicity of electrochemical solid-state cells stacked along a longitudinal axis in a housing. Each of the electrochemical solid-state cells has a stack including at least one anode layer, at least one cathode layer and at least one solid electrolyte layer arranged between the anode layer and the cathode layer. At least one of the electrochemical solid-state cells includes an elastically deformable compensation element, which at least partly compensates for a change in volume along the longitudinal axis of the stacked electrochemical solid-state cells. A method for producing such galvanic elements is also provided. Advantageous applications are found in vehicles and mobile devices including such galvanic elements.

Galvanic element having solid-state cell stack

A composite separator is provided which includes a polymer membrane, a binder, a solid inorganic lithium-ion conductor and a liquid electrolyte. The solid inorganic lithium-ion conductor is present in the composite separator in a higher volume and weight proportion than the liquid electrolyte. A method for forming the composite separator is also provided, and a lithium-ion battery is provided which includes a composite separator having a polymer membrane, a binder, a solid inorganic lithium-ion conductor and a liquid electrolyte.
