Manufacturing of an electrode laminate with a treated carrier foil

A method for a laminated electrode, the method comprising:

• layering a first side of a solid-state electrolyte (SSE) layer adjacent to a conductive electrode as an electrode stack, wherein the SSE layer is cast onto a carrier foil on a second side opposite the first side;
• laminating the SSE layer to the conductive electrode by applying a laminating pressure to the electrode stack;
• removing the carrier foil from the second side of the SSE layer;
• layering the second side of the SSE layer with a treated carrier foil comprising a surface energy for adhering the SSE layer to the treated carrier foil;
• and
• densifying the SSE layer by applying a densifying pressure to the electrode stack, wherein the densifying pressure is greater than the laminating pressure.

A solid-state electrochemical cell comprising;

• a solid-state electrolyte (SSE) layer the first electrode;
• a treated carrier foil cast onto the SSE layer, the treated carrier foil comprising a surface energy for adhering to the SSE layer;
• and
• a conductive layer adjacent the SSE layer to form an electrode stack.

A method for manufacturing a battery electrode, the method comprising:

• coating an electrode layer onto a carrier foil;
• layering a treated carrier foil on the coated electrode layer, the treated carrier foil comprising a surface energy to adhere to the electrode layer;
• and
• densifying the layered electrode layer by applying a densifying pressure to the layered electrode layer, wherein the surface energy retains the adherence of the electrode layer to the treated carrier foil following the densifying of the layered electrode layer.
