METHOD FOR PREPARING LITHIUM MANGANATE HAVING SPINEL STRUCTURE

The process for preparing spinel-type lithium manganate according to the present invention is constituted by a process to admix the electrolyzed manganese dioxide, which is obtained by neutralizing manganese dioxide precipitated by means of electrolysis with any of potassium hydroxide, potassium carbonate and lithium hydroxide, and a lithium material and a process to subject the resulting mixture to a sintering process.
