Abstract

DC60 (23/04/41) Continuous phase of preparation A single-phase intermediate insertion compound of the formula Li1 + xMn2-xO4, which consists of steps of Mixing of lithium hydroxide or lithium salt and manganese oxide or manganese salt. Reactor Continuous shaking of the mixed salt in the reactor The heating of the salt was mixed and shaken in a reactor at temperatures from approximately 650 ° C to approximately 800 ° C for up to approximately 4 hours in an oxygenated atmosphere and the reaction of the products was made. It then cooled to less than about 200 ° C in an oxygenated atmosphere for no more than about 2 hours. Single-phase manganese oxide of the formula Li1 + xMn2-xO4, which consists of a homogeneous mixing process of lithium hydroxide or lithium salts, and manganese oxide or manganese salt. to Reactor Continuous shaking of the mixed salt In the reactor The heating with salt was mixed and shaken in Reactors at temperatures from approximately 650 degrees C to approximately 800 degrees C for up to approximately 4 hours in an oxygenated atmosphere. And making the substances of the reaction products Then cooled to less than about 200 degrees C in an oxygenated atmosphere for no more than about 2 hours
