    Abstract: The present invention relates to a lithium recovery device and recovery method. The lithium recovery device of the present invention includes: a first electrode; a second electrode; and a power supply device. In the lithium recovery device of the present invention, since lithium is attached to an adsorbent of the first electrode by applying a current to the first and second electrodes in a state in which the first and second electrodes are immersed in a lithium-containing fluid, the first electrode including a carrier made of a stainless steel material in a form of an iron mesh or perforated sheet and having a surface coated with the adsorbent containing a manganese oxide, and the second electrode facing the first electrode, it is possible to increase a size of the device and have excellent energy efficiency and economic feasibility.

    Abstract: The present disclosure relates to a system for recovering multiple kinds of ions, which includes: an ion adsorption tank that includes a plurality of adsorption channels arranged in parallel and including a first electrode unit electrically adsorbing only negative ions and a second electrode unit having an adsorbent layer for adsorbing positive ions to be recovered from positive ions, in which electricity is independently supplied to the adsorption channels; a water tank that keeps liquid discharged from the ion adsorption tank; a pump that circulates mother liquor or liquid stored in the water tank; and an ion recovering tank that keeps liquid containing positive ions to be recovered. According to the present disclosure, a series of processes make it possible to continuously recover ions to be recovered, so the operation efficiency of the system can be maximized.
