On-Site Portable Lithium Detection in Mining and Recycling Industries Based on a DNAzyme Fluorescent Sensor.

ABSTRACT: The global demand for lithium has soared in recent years due to the wide use of lithium batteries. To meet this demand, we herein report developing novel on-site sample preparation methods for the extraction of Li⁺ from relevant materials, including brine water, spodumene rock, as well as lithium-ion battery electrodes, and a DNAzyme-based fluorescent sensor for sensitive and robust detection of Li⁺ in these samples down to 1.4 mM (10 ppm) using a portable fluorometer. The system can distinguish key threshold lithium levels that indicate economic value across several industries, including 200 ppm Li⁺ for brine mining, 6 % Li₂O or SC6 for rock mining, and Li⁺-specific aging in LIBs. The methods developed and demonstrated in this work wi
