PROBLEM TO BE SOLVED: To provide a production process which enables securance of the cycle stability over a long period by an interactive combination of the optimization of mixable properties of raw materials so as to very uniformly mix them and control of the firing atmosphere. SOLUTION: This production process for synthesizing a lithium-manganese double oxide from a manganese compound and a lithium compound, comprises: subjecting these powdery raw material compounds to first stage mixing to obtain a first powdery mixture; thereafter, further subjecting the mixture to second stage mixing to obtain a second powdery mixture; and then firing the second powdery mixture as it is or a granulated material from this powdery mixture, in an air stream and/or an oxygen stream, wherein optionally, a source material of at least another element is added to the manganese compound and/or lithium compound. |
