Tracking the EV battery factory construction boom across North America

The onshoring of battery manufacturing for EVs started as a trickle during the COVID-19 pandemic. Then it turned into a tsunami.

In 2019, just two battery factories were operating in the United States with another two under construction. Today there are about 34 battery factories either planned, under construction or operational in the country.

U.S. President Joe Biden’s Inflation Reduction Act (IRA), signed into law August 16, 2022, might not have been the initial catalyst behind the onshoring battery factory trend. But it did help open the spigot and accelerate the pace of factory projects — not to mention sparking a climate tech arms race with the EU. Two years later, we’re still tracking the fallout.

China has long controlled the supply and manufacture of lithium-ion batteries. The country's grip on that supply chain began to loosen after automakers, hesitant to repeat the chip shortage crisis that hampered manufacturing during the pandemic, began promising to build EVs and batteries closer to home in 2021.

What has followed is a wave of automakers and battery makers — foreign and domestic — pledging to produce North American–made batteries before 2030. (See each automaker's plans here and battery maker's plans here.)

IRA carrots and sticks

Why so much investment into onshoring EV battery production? One reason is because the IRA is rife with incentives for automakers and consumers to produce domestically — a concerted effort to end the U.S.’s reliance on China for batteries, while simultaneously meeting Biden’s goal to make 50% of all new vehicle sales in the U.S. electric or hybrid by 2030. Vehicles can qualify for the full $7,500 EV tax credit if they meet certain battery sourcing and production guidelines.

The IRA requires that 60% of the value of battery components be produced or assembled in North America in 2024 to qualify for half of the tax credit, $3,750. That percentage will increase to 100% starting in 2029. To get the remaining half, 50% of the value of critical materials must be sourced from the U.S. or a free trade agreement country in 2024. That percentage increases to 60%, 70% and 80% for vehicles produced in 2025, 2026 and 2027 and beyond, respectively.

The IRA also includes advanced manufacturing credits that give the producer a payout from the Treasury. Under Section 45X, the production of battery cells qualifies for a credit of $35 per kilowatt-hour of capacity, and the production of battery modules qualifies for $10 per kilowatt-hour. (Battery cells are containers that chemically store energy, and they are arranged into modules. Battery packs can be made up of cells or modules.)
