Abstract
This study develops an electrochemical method for directly leaching lithium from α-phase spodumene, a primary lithium ore. The use of an H₂O₂ promoter significantly reduces the leaching potential. A catalyst-modified high-throughput current collector is designed to enhance the process, achieving a leaching current of 18 mA and a leaching efficiency of 92.2%. Electrochemical leaching offers a more sustainable and cost-effective alternative to traditional methods.
