Project Title: From Waste to Treasure: Recycling Valuable Metals from Spent Lithium-ion Batteries for Regenerating High-Capacity Electrode Materials with Micro-/nanostructures

Applicant: Dr. Xiao-Ying LU, Faculty of Science and Technology, Technological and Higher Education Institute of Hong Kong

Total Approved Grant: $454,300 (ECF & WWGF: 50/50)

Duration: 1/5/2017 to 30/4/2019

Project Status/Remarks: On-going

This project aims to investigate valuable metal recycle of spent lithium-ion batteries generated in Hong Kong and to regenerate high-capacity electrode materials with micro-/nanostructures. Specifically, research objectives of this study include:

1. to explore an effective and efficient strategy to recycle valuable metals (e.g. Co and Li) from spent LIBs collected in Hong Kong;

2. to reuse the recycled metals for the regeneration of electrode materials (e.g. Co3O4 negative electrode materials and LiCoO2 positive electrode materials) with micro-/nanostructures;

3. to achieve high capacity and excellent cycling stability of electrode materials in battery performance evaluation and demonstrate their practical applications in button cells for general public use. For this research, a 24-month study is proposed in order to successfully achieve these three objectives.

Summary of the Findings/Outcomes:
To be available upon completion of the project
