METHOD OF PREPARING Li1+xMn2-xO4 FOR USE AS SECONDARY BATTERY ELECTRODE

摘要

A continuous method of preparing a single phase lithiated manganese oxide intercalation compound of the formula Li1+xMn2-xO4 comprising the steps of: mixing intimately a lithium hydroxide or a lithium salt and a manganese oxide or a manganese salt; feeding the intimately mixed salts to a reactor (5); continuously agitating the mixed salts in the reactor (5); heating the agitated mixed salts in the reactor (5) at a temperature of from about 650 DEG C to about 800 DEG C for a time not in excess of about 4 hours in an oxygen-containing atmosphere; and cooling the reacted product to less than about 200 DEG C in an oxygen-containing atmosphere for a time not in excess of about 2 hours.
