The MMSA QP Enhancement Committee offers a series of webinars about a wide range of topics designed for the professionals working for mining companies and those involved in the preparation of studies and disclosure documents. The Webinars are also of interest to the legal, financial, management and academic sectors of the industry. The Webinars qualify for Continuing Professional Development credits for MMSA QPs.

Title: “Can We Make U.S. Battery Supply Chain Sustainable?


The demand for battery metals – in particular lithium – has been growing exponentially in recent years due to the high demand for electric vehicles as well as the general trends nationally and globally for electrification. Worldwide battery markets are expected to grow 5-10-fold over the next decade. While the demand for the battery metals is growing, larger number of lithium-ion batteries (LiBs) are expected to reach end of line and require handling and proper recycling. Meanwhile, the estimate for percentage of batteries collected and recycled continues to be in dispute (from 1-5%).

Building a sustainable supply chain remains questionable in western countries, who have relied heavily in the past years on overseas suppliers, to produce battery grade minerals and to make batteries. Several new companies have been launched in the last few years to recycle LiBs. This presentation will review the current state of battery recycling practices and present the pros and cons of each. New innovations in battery recycling will also be presented.

The U.S. and its allies have established a vision for a secure battery materials and technology supply chain by 2030. Many of the practices today for collection and recycling of batteries remain questionable. Despite large scale investments in recent years, environmental and processing inefficiencies remain. This presents new opportunities for innovation in the sector.
