Title:
PRODUCTION LINE AND PRODUCTION METHOD FOR LITHIUM ION BATTERY POSITIVE ELECTRODE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/098161
Kind Code:
A1
Abstract:
Disclosed in the present invention are a production line and production method for a lithium ion battery positive electrode material. The production line comprises a roller kiln; a gas collection apparatus, which is in communication with the roller kiln and is used for collecting a gas from the roller kiln; and a free lithium measurement apparatus, which is used for measuring the content of free lithium in the gas that is collected by the gas collection apparatus. The production line for a lithium ion battery positive electrode material can monitor the state of free lithium in real time, such that a sintering parameter can be assessed in real time, so as to facilitate real-time adjustment of the sintering parameter, thereby reducing unqualified products, and avoiding the waste of raw materials.
