Abstract

To detect the state of a slurry during stirring without exposure to the atmosphere and with high accuracy. A stirring tank stores a slurry for a battery without exposure to the atmosphere. A stirring device stirs the slurry in the stirring tank. An observation container is coupled to the stirring tank. A circulation device circulates the slurry between the stirring tank and the observation container without exposure to the atmosphere. A detection device detects the state of the slurry by irradiating the slurry in the observation container with X-rays and detecting the X-rays transmitted through the slurry.

Claims (21)

1 . An apparatus for manufacturing a slurry for a battery, the apparatus comprising:

a stirring tank configured to store a slurry for a battery without exposure to an atmosphere;

a stirrer configured to stir the slurry in the stirring tank;

an observation container coupled to the stirring tank;

a circulator configured to circulate the slurry between the stirring tank and the observation container without exposure to an atmosphere; and

a detector configured to detect a state of the slurry by irradiating the slurry in the observation container with X-rays and detecting the X-rays transmitted through the slurry,

wherein an inside of the observation container is formed in a tapered shape that reduces in diameter in a circulation direction of the slurry.

2 . The apparatus according to claim 1 ,

wherein the detector comprises a main body configured to emit and detect X-rays, and a rotator configured to rotate one of the main body or the observation container relative to the other,

wherein the detector is configured to Irradiate the slurry in the observation container with X-rays from a plurality of angles different from each other, and to detect a state of the slurry from the plurality of angles, by way of cooperation between the rotator and the main body, and

wherein the apparatus further comprises a three-dimensional analyzer configured to perform three-dimensional analysis of the slurry based on the state of the slurry detected from the plurality of angles.

3 . An apparatus for manufacturing a slurry for a battery, the apparatus comprising:

a stirring tank configured to store a slurry for a battery without exposure to an atmosphere;

a stirrer configured to stir the slurry in the stirring tank;

an observation container coupled to the stirring tank;

a circulator configured to circulate the slurry between the stirring tank and the observation container without exposure to an atmosphere; and

a detector configured to detect a state of the slurry by irradiating the slurry in the observation container with X-rays and detecting the X-rays transmitted through the slurry,

wherein the detector comprises a main body configured to emit and detect X-rays, and a rotator configured to rotate one of the main body or the observation container relative to the other,

wherein the detector is configured to irradiate the slurry in the observation container with X-rays from a plurality of angles different from each other, and to detect a state of the slurry from the plurality of angles, by way of cooperation between the rotator and the main body, and

wherein the apparatus further comprises a three-dimensional analyzer configured to perform three-dimensional analysis of the slurry based on the state of the slurry detected from the plurality of angles.

4 . The apparatus according to claim 3 , further comprising a stirring controller configured to determine a timing of ending the stirring of the slurry based on a result of the three-dimensional analysis.
