Electrode slurry mixing process

Abstract

The electrode slurry mixing process is to mix materials constituting electrode slurry in a planetary ball mill. The electrode slurry mixing process can produce electrode slurry capable of raising the great current discharge performance, capacity and cycle performance of cell, and can shorten the electrode slurry mixing time and raise production efficiency greatly.

Description

technical field

[0001] The invention relates to a material mixing method, in particular to a mixing method of electrode slurry. Background technique

[0002] At present, the mixing of battery electrode slurry is mainly carried out in conventional magnetic stirrer, mechanical stirrer and other mixing equipment with only a single mechanical stirring method, including the binder, solvent, conductive agent and active material required in the electrode slurry Powder, etc. are simply mechanically stirred and mixed to make a slurry. Obviously, this simple mechanical stirring cannot achieve sufficient mixing of the slurry, so that the uniformity of the slurry cannot be guaranteed, resulting in poor high-current discharge performance, low capacity and poor cycle performance of the resulting battery. Moreover, it takes a long time to mix the slurry in this way, usually more than 6 hours.

[0003] At present, there is a planetary ball mill on the market. The structure of the ball mil...
