The propose method of manufacturing a solid-state lithium battery consists of preparing an anode coated with a solid-state electrolyte precursor and a cathode unit coated with solid-state electrolyte, both precursors containing a predetermined amount of a redundant water. The thus prepared anode unit and cathode unit are pressed to each other through their respective electrolyte precursor layers in a closed chamber at a predetermined elevated temperature and under a predetermined mechanical pressure, whereby an integral pre-final solid-state battery unit is formed. The manufacture of the battery is completed by inserting the prefinal product into a casing that leaves parts of the metal current collectors of the prefinal product exposed for use as a battery anode and a battery cathode.

Method of manufacturing a solid-state lithium battery and a battery manufactured by the method

Proposed is a method of synthesizing a solid-state electrolyte of LiHalO formula for use in a lithium-ion battery. The method consists of uniformly mixing at least LiOH and LiHal in a stoichiometric quantities, heating the prepared mixture to a melting temperature and causing a reaction of formula (2LiOH+LiHal=LiHalO+HO) between the at least LiOH and LiHal in a process free of forming a perovskite structure and at a temperature, at which HO that forms at the aforementioned reaction is converted into a bound form, whereby a reaction product is obtained. According to another modification of the method, prior to the stage of melting the mixture, a reinforcement mesh is immersed into the mixture, whereby after mixture is solidified, a solid-state electrolyte reinforced with the mixture embedded into its material is obtained.
