METHOD FOR PRODUCING LITHIUM MANGANATE AND LITHIUM CELL USING SAID LITHIUM MANGANATE

摘要

A method for producing lithium manganate which comprises preparing a seed of manganese oxide, subjecting the seed to a particulate growth treatment to provide a granule of manganese oxide having a great diameter, and reacting the resultant manganese oxide with a lithium compound, thereby providing a lithium manganate granule having a great diameter. The lithium manganate produced by the method shows a high packing density due to its great granule diameter, and thus can be used for producing a lithium cell having a high energy density.
