A method of producing porous lithium oxide having an average pore spacing not greater than about 20 microns and preferably not greater than about 10 microns, wherein lithium hydroxide is heated above the melting point of anhydrous lithium hydroxide in an inert atmosphere, cooled to a temperature below its melting point in the inert atmosphere, subjected to reduced pressure not exceeding 2 microns of mercury and heated to a temperature of about 150.degree. to about 200.degree. C. under reduced pressure, to obtain porous lithium oxide. Porous microspheres of lithium oxide can be obtained by passing the molten lithium hydroxide through a small bore vertical tube to form a liquid jet which is disintegrated into molten microspheres, cooled and heated under the conditions described above.
