In a chemical reaction device that improves a yield of a product and that causes a reaction, progress of which in a gaseous phase is restricted by a chemical equilibrium between a source material and the product, a cumulative value is not less than 500 mm.sup.2, the cumulative value being obtained by cumulatively adding, from one end to the other end of a cooling surface in a height direction, products of (i) a distance L between (a) a surface of a catalyst layer which surface is in contact with a transmission wall and (b) an outer surface of the cooling surface and (ii) a height H of the catalyst layer corresponding to the outer surface having the distance L.

The present disclosure provides a method for preparing a transition metal lithium oxide, comprising steps of: A) mixing a lithium salt and a transition metal compound, and performing a pretreatment to obtain a precursor; wherein the pretreatment temperature is 100-300° C.; and the pretreatment time is 1-10 h; B) precalcining the precursor to obtain an intermediate; and C) continuously feeding the intermediate into a feed port of a moving bed reactor, and calcining, to obtain a transition metal lithium oxide. In the present disclosure, a pretreatment process is performed before the precalcination, and the pretreatment temperature and time are further limited, thereby solving the problem of material hardening during the calcination process of battery materials. In conjunction with using a moving bed reactor, the gas phase and the solid phase are sufficiently contacted, and at the same time the thickness of the filler is increased, the productivity is enhanced and the oxygen consumption is largely decreased at the same time.
