| 1. A production method of a lithium battery comprising:
applying an active cathode mass on a current collector, anode, separator and non-aqueous electrolyte, the cathode mass comprising
electrochemical active material in the form of metal oxides or sulfides as a compact deposit and having a density of 2.6-4.9
g/cm3;
selecting a cathode active layer thickness within the range of 0.5 μm-3 mm;
adjusting temperature and duration of the temperature while applying a solid electrolyte;
performing controlled cooling of the solid electrolyte, wherein during a transition of the solid electrolyte from a gas phase
to liquid phase, the solid electrolyte penetrates into pores formed on the active cathode mass and the solid electrolyte is
uniformly distributed in an electrode volume; and
providing a thickness of the solid electrolyte layer of 2-10 μm.
