Abstract
Disclosed are an apparatus and method for preparing slurry for a secondary battery. According to the present invention, a solvent is intermittently injected into a mixer for preparing the slurry to measure a torque value applied to the mixer and thereby to obtain a maximum value of the torque value applied to the mixer. Then, a kneading point that is a mixing ratio of the powder and the solvent, which are used for preparing the slurry, is calculated to determine an optimized kneading point without error and through an automatic process.
