▎ 摘　　要

NOVELTY - Electrode comprises a conductive substrate and a coating layer arranged on the surface of the conductive substrate, where the coating layer has a porous structure. The porous structure is formed by decomposition of the amodimethicone-coated pore former. USE - Electrode used to extract lithium from a salt lake (claimed), where the lithium is used in wind power, nuclear power and new energy vehicles. ADVANTAGE - The electrode is easy to prepare, environment friendly, and improves the strength and cycle performance of the electrode plate.
