A method for producing a composite anode having a collector, an active anode material, a binder, an inorganic solid lithium ion conductor, and a liquid electrolyte, the method comprising the steps of:
- combining at least the active anode material, the binder in solution with a solvent, and solid inorganic lithium ion conductor to form a homogeneous slurry;
- applying the slurry to a collector;
- stripping off the solvent under reduced pressure and/or elevated temperature, forming a porosity in the slurry;
- adjusting the porosity by calendaring;
- and
- filling up the porosity with the liquid electrolyte.
