• Integrates with Microwave Joule Heating Technology for solar panel recycling
• Achieves near-complete silver recovery with high purity
• Significantly reduces acid consumption and eliminates heavy metal waste

During the September quarter, Lithium Universe announced the acquisition of the global rights to Macquarie University's Jet Electrochemical Silver Extraction (JESE) Technology. The JESE process utilises a low-voltage electrochemical jet of dilute nitric acid to selectively dissolve silver from solar cells, while preserving the integrity of the underlying silicon wafer. The new technology complements Lithium Universe's existing Microwave Joule Heating Technology (MJHT), which efficiently delaminates solar panels without mechanical grinding or high-temperature furnaces. Together, MJHT and JESE form a comprehensive and sustainable PV recycling platform that positions Lithium Universe at the forefront of critical metal recovery from solar panel waste. The extensive test work program conducted by the Macquarie University team has validated the JESE process, confirming near-complete recovery of over 95% silver, with a purity level of 95.95% within just five minutes. The technology also achieves an 83% reduction in acid consumption compared to conventional hydrometallurgical recycling, while eliminating the need for costly additives and sacrificial metals. The research has demonstrated that the design of the electrode tool plays a critical role in recovery efficiency, with sharp cone geometries delivering superior performance.

The acquisition of the JESE technology, combined with the existing MJHT process, positions Lithium Universe to develop a comprehensive and sustainable solar panel recycling solution that can recover high-value materials like silver and silicon while minimizing environmental impact.
