MetalEco: Sustainable Recovery of Valuable Metals from Spent EV Batteries through Continuous Electrochemical System is a 36-month research project that aims to develop a sustainable and innovative approach for recovering high-value metals from spent electric vehicle (EV) batteries. Specifically, the project focuses on the selective recovery of lithium (Li) through a continuous electrochemical system, followed by the sequential recovery of nickel (Ni), cobalt (Co), and manganese (Mn) from battery black mass through electrowinning.
The project addresses the growing environmental and resource-management challenges associated with end-of-life EV batteries by promoting the recovery and reuse of critical metals rather than disposal through conventional waste pathways. In addition to metal recovery, the project will evaluate the usability of the recovered lithium by incorporating it into a Li-ion coin cell, paired with carbon nanomaterial-based components derived from agricultural waste, demonstrating a circular and sustainable materials approach.
MetalEco is expected to generate valuable metal compounds, support prototype battery component development, provide preliminary cost-benefit data, strengthen academe-industry collaboration, and contribute to policy directions on lithium-ion battery recycling. Overall, the project supports resource efficiency, environmental protection, innovation, and circular economy development in the Philippines.
