摘要： A main object of the present disclosure is to provide a method for producing a sulfide solid electrolyte material, the method that allows a concentration of lithium halide to increase and that allows drying at a low temperature. The present disclosure achieves the object by providing a method for producing a sulfide solid electrolyte material, the method comprising: a drying step of drying a precursor aqueous solution containing LiI, LiBr, and LiOH to remove water and obtain a precursor mixture; and an electrolyte synthesizing step including a sulfidization treatment to sulfurize the LiOH in the precursor mixture and obtain LiHS, a de-sulfide-hydrogenating treatment to desorb a hydrogen sulfide from the LiHS and obtain Li2S, and a synthesizing treatment to make the Li2S to react with an auxiliary material; wherein a molar ratio of the LiOH with respect to the LiI and the LiBr, LiOH/(LiI+LiBr), in the precursor aqueous solution is 3 or more and less than 6.

摘要： Systems and methods of providing self-healing gel-type electrolyte composites for metal batteries are disclosed. According to aspects of the disclosure, a method includes preparing a ternary mixture including an electrolyte portion, a matrix precursor portion, and a self-healing portion, forming a self-healing gel-electrolyte membrane by initiating polymerization of the gel-forming precursor and the gel-forming initiator to thereby form a polymer matrix, and disposing the self-healing gel-electrolyte membrane between an anode and a cathode. The self-healing portion includes a self-healing precursor that is flowable and a self-healing initiator. The matrix precursor portion includes a gel-forming precursor and a gel-forming initiator. The electrolyte portion and the self-healing portion are disposed substantially throughout the polymer matrix and the polymer matrix includes a plurality of gel-forming active sites.

摘要： The present invention relates to the field of solid materials for the adsorption of lithium. In particular, the present invention relates to a new method for the preparation of a crystallized and shaped solid material, preferably in extruded form, of the formula (LiCl)x.2Al(OH)3,nH2O, wherein n is between 0.01 and 10, x is between 0.4 and 1, wherein it comprises a step a) of precipitation of boehmite under specific temperature and pH conditions, a step of bringing into contact the precipitate obtained with LiCl, at least one acid extrusion-kneading shaping step, wherein the method also comprises a final hydrothermal treatment step, all of which makes it possible to increase the lithium adsorption capacity, the adsorption kinetics, as well as the lithium/boron selectivity of the materials obtained with respect to the materials of the prior art, when it is used in a lithium extraction method of saline solutions.

摘要： Disclosed is a method of producing high-purity lithium carbonate and barium sulfate from discarded lithium secondary batteries, including: a first process for producing high-purity lithium phosphate from a discarded battery; and a second process for producing lithium sulfate from the lithium phosphate and producing lithium carbonate and barium sulfate from the lithium sulfate. The second process has steps of (a) producing a liquid mixture of lithium phosphate and sulfuric acid, (b) obtaining lithium sulfate by condensing the liquid mixture, (c) dissolving the lithium sulfate in water or a sodium hydroxide aqueous solution, depositing phosphoric acid as lithium phosphate, and performing solid-liquid separation (d) depositing lithium carbonate and performing solid-liquid separation to obtain lithium carbonate, (e) finely grinding the lithium carbonate and classifying the particles, (f) controlling a particle size and shape by dissolving edges of particles or minute particles, (g) performing solid-liquid separation, and (h) depositing barium sulfate.
