Electrode slurry performance testing device and testing method thereof

Abstract

The invention provides an electrode slurry performance testing device applied to the technical field of lithium ion battery slurry, and further relates to an electrode slurry performance testing method, and one side of a material groove (2) of the electrode slurry performance testing device is movably sleeved in an opening of a stand column I (3) through a rod piece I (5); the other side of the material groove (2) is movably sleeved in the opening of the stand column II (4) through a rod piece II (6), an adjusting shaft (7) is screwed on a threaded part at the outer end of the rod piece II (4), a plurality of flow guide pipes (8) are arranged at the front part of the material groove (2), and a material groove rear cover (10) is arranged at the rear part of the material groove (2).According to the electrode slurry performance testing device and the testing method thereof, the fluidity and the stability of the electrode slurry can be measured at the same time, the coating capacity of the shipment slurry is effectively judged, abnormal materials are found in time to be distinguished and isolated, the quality cost is reduced, and meanwhile, the process capacity of the stirring procedure is analyzed, or the stability of single-formula slurry production is tracked.

Description

technical field [0001] The invention belongs to the technical field of lithium ion battery slurry, and more specifically relates to a device for testing the performance of electrode slurry, and the invention also relates to a method for testing the performance of electrode slurry. Background technique [0002] The production of lithium-ion battery slurry is the first process of lithium-ion battery production, and it is also one of the most critical processes. The fluidity of the slurry is one of the most important parameters for evaluating the quality of the slurry. The industry has always used the measurement results of the rotational viscometer to evaluate the fluidity of the slurry. The results measured by the rotational viscometer mainly show the thixotropy of non-Newtonian fluids, which cannot accurately reflect the fluidity of the slurry during coating, resulting in the inconsistency of slurry fluidity batches during coating production, and the coating process cannot b...

Problems solved by technology

The results measured by the rotational viscometer mainly show the thixotropy of non-Newtonian fluids, which cannot accurately reflect the fluidity of the slurry during coating, resulting in the inconsistency of slurry fluidity batches during coating production, and the coating process cannot be discovered and adjusted in time parameters, resulting in cost losses or quality accidents
