A method for preparing highly active dual-solid waste amorphous precursors by utilizing flash Joule heating in conjunction with the activation of fly ash from waste lithium battery electrode materials.
By combining flash Joule heating technology with waste lithium battery electrode materials, the co-processing of fly ash and waste lithium batteries was achieved, and a highly active amorphous glass phase was prepared. This solved the problem of the difficulty in destroying the stable crystal structure of mullite and quartz in fly ash, improved metal leaching efficiency, and reduced energy consumption and pollution.

Abstract
A method for preparing highly active dual-solid-waste amorphous precursors using flash Joule heating synergistically activated fly ash from waste lithium-ion battery electrode materials belongs to the fields of solid waste resource utilization, environmental engineering, metallurgical engineering, and inorganic non-metallic materials technology. This invention utilizes Zachariasen's rule in glass chemistry, where aluminum in aluminosilicate melts tends to transform from a six-coordinate to a four-coordinate state due to the lack of a charge. Therefore, it is necessary to introduce metal cations for charge compensation. Waste batteries can serve as silicate network modifiers for charge compensation. Furthermore, the graphite anode from waste batteries can serve as a conductive medium in the FJH reaction process.
