Abstract

A CONTINUOUS METHOD OF PREPARING A SINGLE PHASE LITHIATED MANGANESE OXIDE INTERCALATION COMPOUND OF THE FORMULA LI1+XMN2-XO4 COMPRING 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; CONTINUOUSLY AGITATING THE MIXED SALTS IN THE REACTOR; HEATING THE AGITATED MIXED SALTS IN THE REACTOR AT A TEMPERATURE OF FROM ABOUT 650°C TO ABOUT 800°C FOR A TIME NOT IN EXCESS FOR ABOUT 4 HOURS IN AN OXYGEN-CONTAINING ATMOSPHERE; AND COOLING THE REACTED PRODUCT TO LESS THAN ABOUT 200°C IN AN OXYGEN-CONTAINING ATMOSPHERE FOR A TIME NOT IN EXCESS OF ABOUT 2 HOURS.
