Title:
SLURRY VISCOSITY PREDICTION METHOD AND APPARATUS FOR LITHIUM ION BATTERY, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066053
Kind Code:
A1
Abstract:
Disclosed in the present invention are a slurry viscosity prediction method and apparatus for a lithium ion battery, and a related device. The method comprises: acquiring slurry state data of target slurry within a first time period, wherein the target slurry is slurry used for preparing a lithium ion battery, the slurry state data comprises a processing temperature, a processing shear force, a processing shear rate and slurry viscosity sequence data within the first time period, and the first time period comprises a coating time period of the lithium ion battery; acquiring a target temperature, a target shear force and a target shear rate of the target slurry within a second time period, wherein the second time period is after the first time period, and the second time period comprises a film-coating drying time period; and according to the target temperature, the target shear force, the target shear rate and the slurry state data, predicting the viscosity of the target slurry within the second time period by means of a trained slurry viscosity prediction model, and obtaining corresponding slurry viscosity prediction data. The present invention facilitates the prediction of the viscosity of lithium ion slurry within a film-coating drying time period.
