Abstract
An electrochemical method and an apparatus for extracting lithium from a solution using bipolar electrodes are provided. The apparatus adopts electrodes respectively coated with a lithium-rich electroactive material and a lithium-deficient electroactive material as end plates, which are separated by a plurality of bipolar electrodes coated with a lithium-rich electroactive material and a lithium-deficient electroactive material respectively on two sides, where the side of the bipolar electrode facing the end plate of the lithium-rich electroactive material is coated with the lithium-deficient electroactive material, and the side of the bipolar electrode facing the end plate of the lithium-deficient electroactive material is coated with the lithium-rich electroactive material. The apparatus adopts a conventional voltage, requires a small total current and a simple power supply, greatly reduced the amount of busbar required, allows for easy process control, and is suitable for industrial production.
