General Motors is pursuing early-stage development of next-generation battery cells designed to minimize reliance on Chinese materials and maximize domestic sourcing. Kurt Kelty, GM’s vice president of battery and sustainability, stated the company aims to establish a fully domestic supply chain within two to three years for battery cells used in energy storage systems and electric vehicles.
GM has partnered with Denver-based startup Peak Energy to develop sodium-ion battery cells that would utilize more abundant domestic materials such as sodium from soda ash, rather than materials like lithium and ferrous sulfate where China maintains significant control. The company expects to begin commercial production of these cells around 2029. Currently, GM manufactures lithium iron phosphate cells with LG Energy Solution in the U.S. for energy storage applications, while continuing to source materials from China in the interim through other joint ventures.
The development effort comes amid heightened government attention to battery supply chains. The Trump administration has prioritized strengthening U.S. battery production and reducing Chinese dependence. Earlier this week, Transportation Secretary Sean Duffy expressed concern regarding Ford’s licensing arrangement with China’s CATL for lithium iron phosphate battery cell technology, despite Ford being the nation’s largest vehicle manufacturer.
Kelty characterized GM’s strategy as an attempt to “leapfrog” existing Chinese battery technologies rather than compete directly with established supply chains. He emphasized sodium-ion’s advantages for energy storage, particularly its temperature tolerance that eliminates the need for active cooling systems, thereby reducing operational costs and complexity. Battery experts note that while developing a domesticated supply chain will require years of effort, such initiatives could eventually address China’s dominance, which currently accounts for approximately 85 percent of global EV battery cathode production and over 90 percent of anode material production.
GM is investing $900 million in new battery laboratory facilities at its Detroit-area technology campus, including a 500,000-plus square-foot prototyping manufacturing facility scheduled to begin operations later this year.
