摘要:The invention provides a process for preparing anhydrous lithium bromide, comprising the steps of converting an aqueous suspension of lithium carbonate with hydrobromic acid into a solution of lithium bromide; removing residual carbon dioxide from the solution by gas-stripping, wherein the solution has acidic pH; neutrali zing the acidic lithium bromide solution by addition of lithium hydroxide to form lithium bromide brine with a nearly neutral pH; and recovering anhydrous lithium bromide from the brine. The so- formed anhydrous lithium bromide is used as a starting material in the mechanochemical synthesis of bromide-containing Li-argyrodite, which is useful in the fabrication of all-solid-state battery.

摘要:The invention relates to a continuous process for preparing carbon-coated lithium-iron-phosphate particles, wherein the carbon-coated lithium-iron-phosphate particles have a mean (d 50 ) particle size of 10 to 150 nm, and wherein the carbon-coating is an acetylene-black coating, comprising performing in a reactor a flame-spray pyrolysis step (i) in a particle formation zone of the reactor, and a carbon-coating step (ii) in a carbon-coating zone of the reactor, wherein inn (i) a combustible organic solution containing a mixture of lithium or a lithium compound; iron or an iron compound; and phosphorus or a phosphorous compound in an organic solvent, is fed through at least one nozzle where said organic solution is dispersed, ignited and combusted, to give a flame spray thereby forming an aerosol of lithium iron phosphate particles; (ii) acetylene gas is injected into said aerosol thereby forming an acetylene-black coating on the lithium iron phosphate particles; (iii) the coated particles are cooled by an inert quench gas and collected on a filter.
