Abstract: A method of producing a particulate lithium metal oxide or lithium metal phosphate material comprising the steps of providing one or more metal compounds, adding sufficient water to dissolve the one or more metal compounds to form a metal compound solution, adding a first basic solution, a second basic solution and the metal compound solution at predetermined rates to a reaction vessel containing water to form a reaction mixture, heating the reaction mixture while maintaining a pH of the reaction mixture in a predetermined pH range, adding a lithium compound, adding a fatty acid, filtering a precipitate, washing and preferably drying the precipitate, calcining the dried precipitate in an atmosphere containing oxygen to form a calcined lithium metal oxide or lithium metal phosphate, cooling and sizing the calcined lithium metal oxide or lithium metal phosphate to produce a particulate lithium metal oxide or lithium metal phosphate material having a predetermined average particle size.

Abstract: A method of producing a particulate lithium metal oxide cathode material comprising the steps of providing an organic acid, providing a lithium compound, and providing a metal compound. The organic acid, the lithium compound, and the metal compound are mixed to form a mixture. The organic acid is melted to form a liquid organic acid, if the organic acid is provided as a solid. The mixture, including the liquid organic acid, is cCalcined in an atmosphere containing oxygen to form a lithium metal oxide. The lithium metal oxide is cooled and sized to produce the particulate lithium metal oxide having a predetermined average particle size.

Abstract: This disclosure provides systems, methods, and apparatus related to lithium-ion batteries. In one aspect, a method includes synthesizing an intermediate selected from a group of a nickel-manganese-cobalt nitrate, a nickel-manganese-cobalt acetate, a nickel-manganese-cobalt sulfate, a nickel-manganese-cobalt chloride, and a nickel-manganese-cobalt phosphate. The intermediate is mixed with a lithium salt selected from a group of LiOH, LiCl, LiNO3, LiSO4, LiF, LiBr, Li3PO4, Li2CO3, and combinations thereof to form a mixture. The mixture is annealed at a sequence of temperatures and times to form a plurality of single crystals of a lithium nickel-manganese-cobalt oxide, with no cooling of the mixture between operations of the sequence of temperatures and times.

Abstract: This disclosure provides systems, methods, and apparatus related to composite cathodes for all solid-state batteries. In one aspect, an all solid-state battery comprises a composite cathode, a separator, and an anode.
