Abstract
According to a system and method for evaluating the dissolution quality of a binder solution for a secondary battery electrode, by preparing an electrode slurry with a binder solution having a predetermined amount or more of cumulative filtration amount or a predetermined level or less of flow rate reduction rate, the quality of an electrode for a secondary battery may be improved.
Claims20
A system for evaluating dissolution quality of a binder solution for a secondary battery electrode, comprising:
- a pressure vessel accommodating the binder solution;
- a pressure medium source supplying a pressure medium at a predetermined pressure to the pressure vessel;
- a filter connected with the pressure vessel by a pipe;
- and
- a flow rate measurement part that measures at least one of a) or b) with respect to the binder solution passing through the filter when the binder solution in the pressure vessel is transferred to the filter by the pressure medium supplied to the pressure vessel and filtered:
- a) a cumulative filtration amount of the binder solution for a first period of time;
- and
- b) a flow rate reduction rate of the binder solution after a second period of time with respect to an initial flow rate.
A method for evaluating dissolution quality of a binder solution for a secondary battery electrode, comprising:
