E-MINERALS

Extraction of Mineral Nickel and Raw materials recovery Leveraging Philippine Local resources for energy Storage applications

Project 2: Recovery of Lithium and valuable metals from local spent EV Li-ion batteries: waste battery mining, repurposing and regeneration

The E-MINERALS Program, headed by Dr. Rinlee Butch Cervera and housed at the DMMME, UPD, aims to develop a local or home-grown extraction and recovery technology, leveraging our local mineral resources and materials for energy storage applications, such as EV Li-ion batteries. Apart from this, the E-MINERALS Project 2 under the program focuses its efforts in recovering lithium and other valuable metals such as Co, Mn, and Ni from spent or waste LIBs, and regenerating the battery electrodes. The project also aims to propose a recovering/recycling policy for spent Li-based batteries. With all these, the overall goal is to achieve a sustainable and circular economy at least in the EV sector.
The general method includes collection of spent EV batteries from partner agencies, profiling these batteries, and development of recovery and regeneration procedures which are facile, cost-effective, highly efficient, and environmentally-friendly. With the E-MINERALS Program, the following benefits can be achieved: technical support to local EV industries, environmental impact through decreased raw material mining and disposal, job opportunities in the EV sector, and research output propagation.
