Slurry pressurizing and filtering apparatus for analyzing slurry and method of analyzing slurry

A slurry pressurizing and filtering apparatus comprising:

• one or more processors;
• and
• a memory operatively connected to the one or more processors and configured to store at least one code executed by the one or more processors,
• wherein the memory is configured to store the at least one code to, if executed by the one or more processors, cause the one or more processors to:
• collect a cumulative discharge amount of a slurry of an active material for a secondary battery at preset time intervals;
• calculate a discharge amount per hour of the slurry by using a cumulative discharge amount of the slurry at a previous time and a cumulative discharge amount of the slurry at a current time;
• classify state information of the slurry based on the cumulative discharge amount of the slurry and the discharge amount per hour of the slurry;
• and
• derive a discharge rate, which represents flow characteristics and a dispersion state of the slurry, as an evaluation characteristic value based on a result of classifying the state information of the slurry.
