This technology relates to an electrochemical lithium recovery device and method. In particular, it is a technology designed to enhance the performance, structural stability, and application efficiency of electronic devices and circuit designs by utilizing ZIF-8/CNT flow electrode materials in a second flow electrode module to selectively absorb lithium ions.
Conventionally, existing methods suffered from low selectivity in lithium ion extraction, which could lead to performance degradation, process complexity, lack of stability, or limitations on the scope of application. Accordingly, this technology proposes a technical concept that implements a first flow electrode module by applying a first flow electrode module and a separator module as core means to extract ionic substances from a target solution containing spent battery active materials through electrical attraction.
As a result, an effective lithium ion collection effect can be expected in an electrochemical device for lithium recovery, and stability, reproducibility, and scalability in actual operating environments can be simultaneously enhanced by utilizing ZIF-8/CNT flow electrode materials in the second flow electrode module to selectively absorb lithium ions. Furthermore, it has the potential to be utilized as a high-performance material, device, apparatus, or process technology in related industries; it is advantageous in terms of subsequent commercialization and process expansion, and is also suitable for demonstration deployment.
