Abstract

The present invention discloses production equipment and a technology for a cathode material or an anode material of a converter-type lithium battery, the production equipment comprises a feeder, a fluidized bed mixing device, a gas-solid settlement separation component, a flue pipe, a converter, a combustor, a discharge duct, a motor and a particle cooler; the technical process comprises the following steps the prepared raw materials enter into the fluidized bed mixing device through the feeder, air is introduced and mixed with the prepared raw materials, then is carried with air to the gas-solid settlement separation component, the raw materials are separated with air and enters into the converter, then reacted at 500-900 DEG C to generate the lithium battery cathode or anode material, the produced lithium battery cathode or anode materials are delivered into the particle cooler and then discharged. The production equipment solves the defects of low automation degree, discontinuous production in original equipments, and the lithium battery cathode or anode materials can be produced with high efficiency, low energy consumption and continuous production.

Description

technical field [0001] The invention relates to a production equipment and process for positive or negative materials of lithium batteries, in particular to a production equipment and process for continuous production of positive or negative materials for lithium batteries in a converter. Background technique [0002] Lithium battery is a kind of high-efficiency battery, which is widely used in mobile electronic communication equipment such as mobile phones, notebook computers, radio stations and electric vehicle batteries. At present, the relatively mature production and preparation method of lithium battery cathode or anode materials is solid-phase synthesis, whose main characteristics are simple process flow and easy control of preparation conditions. Taking the preparation process of lithium manganate cathode material as an example, Li 2 CO 3 with MnO 2 The raw material particles are mixed and calcined at a high temperature of 500-900°C for several hours to obtain lit...
