'Don't put all your eggs in one basket'—that seems to be the philosophy driving General Motors' current strategy. While the automaker is moving forward with a new generation of internal combustion engines, it's equally committed to advancing electric vehicle (EV) battery technologies. GM's focus is clear: enhance battery quality, extend driving range, improve charging speed, and lower overall cost.
At the heart of this effort lies an ambitious research initiative involving seven distinct battery chemistries. Among these, sodium-ion, solid-state batteries, and silicon-based anodes stand out as particularly promising, and each plays a unique role in GM's vision for next-generation EVs.
GM's Rise to the Top of the Battery Industry
GM has emerged as a dominant force in battery development, now standing as the largest battery cell producer in North America—surpassing Tesla—thanks to its joint venture with LG Energy Solution. A key contributor to this leadership is the Wallace Battery Cell Innovation Center in Michigan, established in 2022. This facility gives GM full control over the development pipeline, from raw material selection to vehicle integration, allowing for rapid innovation and scalable production in-house.
Sodium-Ion Batteries: Abundant and Affordable
Sodium-ion batteries are still early in their development, but their advantages make them a compelling alternative to lithium-based cells. They're safer, perform better in cold temperatures, and rely on sodium—a material that's about 400 times more abundant than lithium. With countries like China already deploying sodium-ion batteries in production vehicles, GM is leveraging its technical know-how to explore viable use cases and build out the necessary supply infrastructure.
Solid-State Batteries: The Energy Storage Breakthrough
Solid-state batteries are widely considered the future of EV power storage. By replacing traditional liquid electrolytes with solid materials like ceramics or sulfides, these batteries can deliver higher energy density, greater safety, and faster charging times. Although manufacturing at scale remains a challenge, GM is actively pursuing this frontier through ongoing research at the Wallace Center, alongside global players like Toyota, BMW, and Mercedes-Benz.
Silicon Anodes: A Leap in Performance
Another area of focus for GM is the use of silicon in battery anodes. Replacing or supplementing graphite with silicon significantly boosts energy capacity and shortens charging time. GM is already conducting real-world tests of large-format silicon cells built to automotive standards, laying the groundwork for future implementation across its EV lineup.
Looking Ahead: LMR Batteries and the 2028 Vision
By 2028, GM plans to debut its first production vehicle powered by lithium manganese-rich (LMR) prismatic cells. These new batteries are expected to offer more than 400 miles of range, reduce overall vehicle weight, and cost similarly to today's lithium iron phosphate (LFP) options.
While some chemistries may take longer to mature, GM's commitment to innovation remains firm—even amid shifting political landscapes. Attempts to dismantle clean energy initiatives won't derail its long-term battery R&D.
Ultimately, GM's expansive investment in diverse battery technologies is a reflection of its long-term vision: to lead the future of electric mobility through science, adaptability, and self-reliance.
