Revolutionizing EV Battery Circularity
MCJ Startup Series with Nth Cycle

Today's guest is Megan O'Connor, CEO and Co-Founder of Nth Cycle

Nth Cycle uses a metals processing technology that allows battery manufacturers to convert lower-grade critical metals into EV-battery grade on-site. The company’s approach obviates large portions of cumbersome and dirty metal supply chains for crucial EV battery metals like nickel. Megan claims that Nth Cycle's technology can be applied to existing batteries just as it can be to newly mined ore, thus accelerating circularity for the lithium-ion battery and battery recycling.

One significant component of the Inflation Reduction Act is the formalization of US EV tax credits, and a qualification requirement that automakers must source at least 40% of their EV battery components - by value - in the United States or countries with which the US has a free trade agreement starting this year, with escalation to 100% by 2029.

With this change in the backdrop, Megan and Cody have a great conversation about the state of EV battery metal supply chains and battery recycling today, how Megan started working on this problem in the first place, how Nth Cycle works, and what her plans are for the company. We have focused quite a bit recently on EV batteries and the underlying metals that power them on the podcast.
