Electrode attachment/detachment device and an electrochemical cell for measuring electrode characteristics including the same

Electrochemical cell with detachable electrodes featuring magnetic coupling, elastic ring fixation, and a laser measurement window

This technology features a sealed electrochemical cell designed with a magnetic or elastic attachment mechanism for easy electrode mounting and removal, along with a glass window for laser beam measurement, allowing for the simultaneous analysis of electrochemical and mechanical behavior.

Conventional cell assembly methods make it difficult to attach and detach plate-type or flexible electrodes within a glovebox. Furthermore, there have been limitations in maintaining airtight seals and precise electrode alignment required for the simultaneous observation of mechanical and electrochemical behavior.

This technology utilizes the magnetic attraction between a magnetic component and a cover, or applies pressure using an elastic ring and locking tabs to securely and easily fix the electrode in place. It is configured with a Teflon box equipped with a laser-transmitting glass window and an alignment device to ensure measurement efficiency and airtight integrity. Applicable to in-situ electrode deformation analysis and quality inspection equipment in battery research labs, it reduces sample replacement time within gloveboxes and minimizes alignment deviations between measurements, thereby enhancing data reproducibility.

Key Features:

• An electrode connection unit that provides a space for one side of the electrode to be installed, featuring an electrode groove that corresponds to the shape of the plate electrode.
• Magnetic components installed on both sides of the electrode groove within the electrode connection unit, designed to couple with the magnetic protrusions of the cover.
• A cover formed in a plate shape that contacts the other side of the electrode, featuring a mass transfer hole to facilitate material transport to the electrode.
• An alignment device that rotates the electrode attachment/detachment mechanism to align one side of the electrode parallel to the laser-transmitting glass of the Teflon box.
