ELECTRODE FOR THE ELECTROCHEMICAL EXTRACTION OF LITHIUM

Claims

The present invention relates to an electrode for the electrochemical extraction of lithium, belongs to the technical field of the development and utilization of lithium resources, and aims to solve the problems in the existing electrode for the electrochemical extraction of lithium, namely that the bonding force between the substrate and the active material is low, which makes the active electrode material detach easily, the potential distribution on the surface of the electrode is not uniform, which makes the polarization severe, the electron transmission path is far away and the current density is low.An electrode for the electrochemical extraction of lithium comprises a titanium mesh and a lithium extraction slurry. The titanium mesh consists of a plurality of ordered mesh unit holes. The lithium extraction slurry is applied as a coating uniformly over the mesh unit hole structure of the titanium mesh, and the coating density of the lithium extraction slurry is 60–150 mg / cm². The bonding strength between the active electrode material and the electrode surface is high, and the active electrode material does not easily detach. The potentials on the electrode surface are approximately equal, and the electrodes are difficult to polarize. The current transmission path is short.
