Abstract: 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.

Abstract: Proposed is a method of synthesizing a solid-state electrolyte of Li3HalO 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=Li3HalO+H2O) between the at least LiOH and LiHal in a process free of forming a perovskite structure and at a temperature, at which H2O 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.

Abstract: A method of manufacturing porous electrodes based on the use of a CNT tapes is proposed. The pore size of the CNT tape material is regulated by using chemical reactions of active gases with carbon on the surfaces of the pores so that when gaseous reaction products leave the pores, the pore sizes increase, and when solid reaction products precipitate on the pore walls, the pores decrease. By selecting conditions for the chemical interaction of the active components, it is possible to achieve optimal pore sizes due to their increase or decrease. Optimal pore sizes are understood to mean sizes that will make it possible to obtain batteries or super capacitors with improved characteristics.
