▎ 摘　　要

NOVELTY - Preparing seawater lithium extracting system based on solar energy drive comprises e.g. choosing electrode material with specificity for lithium ion selection as cathode material, preparing the cathode adopts the way of spin coating or dipping and pulling, the spin coating is specifically as: lithium enrichment material and conductive agent, binder according to the proportion, under the action of the solvent, using mortar to grind, coating the uniformly ground slurry on the current collector, lighting seawater extracting lithium respectively of the cathode and the light anode into the sea water electrolyte flowing through the peristaltic pump, receiving electron by manganese dioxide, catalytic electron and dissolved oxygen in the seawater reaction and continuously carrying out illumination lithium extraction process. USE - The method is useful for preparing seawater lithium extracting system based on solar energy drive. ADVANTAGE - The method: is simple in structure, economical and environmentally-friendly; and has high stability, high safety performance and high practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for seawater lithium extracting system based on solar energy drive, is prepared by the above method.
