Sodium-ion batteries are gaining momentum in 2026 as major automakers and Wall Street analysts point to a fast-growing market with strong long-term potential. Morgan Stanley says this technology could help create a “new oil age” as sodium becomes more valuable in global energy storage. Moreover, the bank sees sodium-ion batteries taking a meaningful share of the battery market over the next decade.
Sodium-Ion Batteries Could Reshape Energy Storage
Morgan Stanley analyst Jack Lu and his team expect sodium-ion batteries to account for 20% of global battery deployment by 2030. They also project that share will rise to 37% by 2035. For comparison, the technology is expected to represent just 2% of the market in 2027. Therefore, the projected growth curve is steep and notable.
Lu estimates the Sodium-ion Battery market will reach 830 gigawatt-hours by 2030. In addition, he expects it to expand to 2.4 terawatt-hours by 2035. These figures suggest that sodium-ion chemistry could become a major force in both transportation and stationary storage. As a result, investors and manufacturers are paying closer attention.
Morgan Stanley also believes the sector could attract nearly $800 billion in new investments by 2035. That level of capital points to strong confidence in the technology’s commercial future. Furthermore, it reflects growing demand for dependable battery supply in an AI-driven, power-hungry world.
Why Sodium-Ion Batteries Are Drawing Interest
Sodium-ion batteries offer a clear cost advantage. According to Morgan Stanley, they can cost 30% to 40% less than lithium iron phosphate, or LFP, batteries. Lower costs matter because automakers, utilities, and industrial users all want affordable storage at scale. Consequently, sodium-ion batteries stand out as an attractive option.
The technology also performs well in cold weather. That benefit can improve reliability in regions with lower temperatures. In addition, sodium is abundant and inexpensive in the United States. Because of that, companies may have more flexibility to build domestic supply chains around this chemistry.
Lu tied the growth outlook to rising electricity demand from artificial intelligence and digital infrastructure. He said sodium-ion batteries can help address the meeting point between energy security and AI power needs. In other words, the technology fits well with the next wave of electricity consumption.
General Motors Builds an Early Sodium-Ion Batteries Position
Morgan Stanley analyst Andrew Percoco said General Motors has an “early foothold” in the U.S. sodium-ion battery market. GM has taken that position through its partnership with Peak Energy, which focuses on next-generation sodium-ion batteries. As a result, GM has become one of the most closely watched U.S. automakers in this emerging segment.
GM has already put more than 250,000 Electric Vehicles on the road that support bidirectional charging. That feature can help vehicle-to-grid programs by allowing energy to move between vehicles and the grid. Meanwhile, the company is expanding beyond vehicles into stationary energy storage.
GM is also developing sodium-ion batteries for future uses in defense and mobility applications. According to Percoco, the company expects grid-scale energy storage deployments to begin after 2028. At the same time, GM is working with Redwood Materials to improve battery recycling and support a circular supply chain. Together, these steps show that GM is building a broad battery and energy platform.
BYD Adds Momentum to Sodium-Ion Batteries
BYD has also moved quickly in sodium-ion batteries. Earlier in 2026, the Chinese automaker introduced sodium-ion battery technology with a projected lifespan of 10,000 cycles. That figure stands far above the roughly 1,500 to 3,000 cycles often seen in current battery ranges mentioned in the report. Therefore, BYD’s announcement added more momentum to the market narrative.
BYD’s progress matters because the company already competes closely with Tesla in electric vehicles. When a large EV maker invests in a new battery chemistry, the broader market tends to take notice. Consequently, sodium-ion batteries now look more like a commercial growth story than a niche research theme.
Sodium-Ion Batteries and the Road Ahead
Sodium-ion batteries are shaping up as one of the most important battery trends to watch in 2026 and beyond. Morgan Stanley’s forecasts point to rapid adoption, major capital inflows, and expanding use cases. In addition, automakers such as GM and BYD are helping push the technology toward larger-scale deployment.
If these projections hold, sodium-ion batteries could play a major role in electric vehicles, grid storage, and energy security. Their lower cost, strong cold-weather performance, and abundant raw materials support that outlook. For now, Morgan Stanley’s “new oil age” label captures the market’s growing belief that sodium may become a central ingredient in the next era of global energy storage.
