System for manufacturing electrode for secondary battery having scratch tester
Disclosed is a system for manufacturing an electrode for a secondary battery, which includes an active material drying unit configured to dry an active material coated on an electrode current collector, and a tester unit configured to measure a dried state of the active material by performing a scratch test to the dried active material.
1. A system for manufacturing an electrode for a secondary battery, comprising:
an active material drying unit configured to dry an active material coated on an electrode current collector; and
a tester unit configured to measure a dried state of the active material by performing a scratch test to the dried active material.
2. The system for manufacturing an electrode for a secondary battery according to claim 1 ,
wherein the tester unit measures a force applied to the tester unit when a scratch is generated at the electrode active material.
3. The system for manufacturing an electrode for a secondary battery according to claim 2 , further comprising:
a control unit configured to control a drying temperature of the drying unit according to a change of the force measured by the tester unit.
4. The system for manufacturing an electrode for a secondary battery according to claim 1 , further comprising:
a carrying unit configured to carrying the electrode current collector and the electrode.
5. The system for manufacturing an electrode for a secondary battery according to claim 1 , further comprising:
a coating unit configured to coat an electrode active material on the electrode current collector.
6. The system for manufacturing an electrode for a secondary battery according to claim 1 ,
wherein the tester unit includes a scratch tester located on an electrode active material completely dried by the drying unit to generate a scratch on the electrode active material as the electrode moves.
7. The system for manufacturing an electrode for a secondary battery according to claim 6 ,
wherein the tester unit further includes a rotary shaft connected to the scratch tester and installed so that the scratch tester is rotatable thereon.
8. The system for manufacturing an electrode for a secondary battery according to claim 7 ,
wherein the tester unit further includes a torque sensor configured to measure a torque applied to the rotary shaft when the scratch is generated.
9. The system for manufacturing an electrode for a secondary battery according to claim 1 , further comprising:
a display unit configured to display the dried state of the active material, measured by the tester unit.
