AI Technical Summary
Existing flow electrode capacitive deionization (FCDI) systems are prone to local dead zones, particle agglomeration, and conductive network breakage under high solids content slurry conditions. This leads to increased slurry flow resistance and intensified concentration polarization at the membrane interface, which in turn limits lithium-ion migration efficiency and the system's continuous operation capability.
A flow electrode device based on Tesla channels is adopted. By constructing a multi-level asymmetric flow-guiding structure, the Tesla channels are used to regulate the fluid dynamics behavior inside the flow electrode slurry by utilizing their unidirectional flow guidance and local disturbance characteristics, so as to achieve uniform distribution of slurry particles, construction of continuous electronic conductivity network and enhanced ion migration.
It improves the continuous lithium extraction efficiency and charge efficiency of the FCDI system under high solids content slurry and complex brine conditions, enhances operational stability, and is suitable for lithium resource recovery from salt lake brine, seawater and low-concentration lithium-containing waste liquid.
