Morgan Stanley has elevated sodium-ion batteries from an emerging alternative to lithium to the centerpiece of what it calls a “New Oil Age,” arguing the technology could unlock an investment wave worth roughly $800 billion by 2035 and reshape both energy infrastructure and parts of the artificial intelligence supply chain.
In a new research report, the bank projects sodium-ion battery deployment will accelerate from a small foothold—about 2% of global battery deployment in 2027—to a much larger share by the end of the decade. It forecasts sodium-ion reaching 20% by 2030 and rising further to 37% by 2035, with annual deployment climbing to 2.4 terawatt-hours (TWh). Under an optimistic scenario, annual deployment could reach 3.7 TWh. The growth is expected to stimulate investment across battery manufacturing, energy storage deployments, upstream materials, and grid and power connectivity.
The core rationale is not simply that sodium-ion is cheaper than lithium-ion on paper. Morgan Stanley frames the technology as a strategic answer to a bottleneck emerging at the intersection of power-intensive AI growth, energy security priorities, and supply-chain sovereignty—where affordability, speed of deployment, and resilience to critical minerals matter as much as decarbonization alone.
Three advantages are positioned as especially relevant to AI-era power demand. First is supply independence: sodium-ion batteries do not rely on lithium. Second is material and cost structure. The report says sodium-ion uses hard carbon instead of graphite for the anode, and it replaces copper foil current collectors used in lithium batteries with aluminum foil, lowering material costs. Third is performance in cold conditions, which the report portrays as a decisive factor for regions where AI infrastructure and data-center buildout are pushing into colder latitudes.
Morgan Stanley emphasizes that system design for grids and data centers often does not require the absolute maximum energy density; instead, batteries must deliver safe, reliable output, remain affordable, and perform consistently across temperatures. In that context, the bank highlights low-temperature capacity retention as a standout feature. It claims sodium-ion can retain roughly 90% of capacity at -20°C, while lithium iron phosphate (LFP) batteries retain only about 50% to 60% under similar conditions—an economic swing that could reduce the need for expensive thermal management and help prevent winter performance discounts that have historically hurt storage economics.
Cost trajectories are also part of the investment case. The report estimates cell costs could fall from about 0.35 yuan per watt-hour (Wh) to 0.22 yuan per Wh, a reduction of around 36%, describing the decline as tracking lithium-ion’s historic cost curve during its scaling years.
Stationary energy storage is identified as the first—and most explosive—market. Morgan Stanley argues that as costs fall, more storage projects become financially viable, not merely replacing older assets but expanding the pool of deployable capacity. It suggests that if sodium-ion achieves economic parity with existing LFP storage, it could increase the storage capacity deployed per megawatt of solar photovoltaic (PV) by about 50%. In market-share terms, the bank expects sodium-ion to represent 26% of global energy storage installations by 2030, rising to 60% by 2035.
Commercial vehicles are next in line, and the report treats their economics as fundamentally different from passenger cars. For fleet operators, utilization rates, reliability, and energy cost per kilometer drive decisions more than long-range performance alone. Morgan Stanley points to a cold-weather problem in today’s battery supply: in northern and western China, it estimates roughly half of light commercial vehicles operate in conditions where LFP experiences 40% to 50% energy loss in winter. Because it claims sodium-ion retains around 90% of capacity at -20°C, the technology could directly address whether vehicles can operate through winter without significant range penalties.
The report also projects a faster payback in electrified fleets where electricity costs per kilometer are typically far below diesel. In emerging markets, Morgan Stanley estimates electricity costs are often 3 to 5 times lower than diesel. If sodium-ion cell costs are 30% to 40% below LFP, it forecasts payback periods for high-utilization vehicles could compress to 1 to 2 years, shortening them by more than a year in parts of northern China—equivalent to a 30% to 50% improvement. It then sets a global penetration path for commercial vehicles of 43% by 2030 and 66% by 2035.
Passenger vehicles are seen as a later entry point, but with a specific opening: small cars. Morgan Stanley claims sodium-ion energy density has reached about 175 Wh/kg—near current LFP levels. That puts sodium-ion within striking distance for compact urban EVs, where buyer priorities often tilt more toward price than maximum range. The report suggests a product window for entry-level EVs under $15,000 with ranges below 500 kilometers, supported by better low-temperature performance and improved safety characteristics.
Industrial momentum is cited as already visible. The report references BYD’s plan to build a 30 GWh sodium-ion battery factory using 10 billion yuan (about $1.5 billion), with targets spanning ultra-low-priced city cars such as the Seagull. It also points to mass-produced offerings from CATL and Changan.
Beyond batteries themselves, Morgan Stanley frames the $800 billion investment estimate as spanning the full ecosystem. Energy storage deployment is expected to account for the largest share (about $360 billion, roughly 45%), followed by manufacturing capacity (about $135 billion) and supply-chain and raw materials (about $115 billion). Logistics electrification and grid infrastructure are also included, reflecting the idea that large-scale adoption would reach well beyond factory lines into power substations, transmission reinforcement, and connection upgrades.
Still, the report warns that risks could slow or distort the optimistic scenario. It flags the challenge of cost translation from cell level to full system level: if sodium-ion’s system cost advantage proves far smaller than the projected 30% to 40%—say only 5% to 15% cheaper than LFP—the penetration curve could flatten. It also points to supply-chain bottlenecks, especially around hard carbon anodes and other chemistry components that may not match graphite-oxide supply maturity. Another concern is “economic reflexivity”: if sodium-ion erodes lithium demand and lithium prices fall, LFP competitiveness could improve, tightening sodium-ion’s economic window.
Finally, Morgan Stanley emphasizes that customer validation cycles—particularly for large-scale storage and automotive—can be slow and warranty-driven. For sodium-ion to displace LFP at scale, it must clear long-term degradation evidence, safety certification, and warranty requirements.
Geographically, the report suggests China is leading industrialization. It also characterizes U.S. commercialization as earlier-stage, focused on grid-scale storage and data-center or backup power, while Europe and South Korea are developing strategies at different paces. Across regions, though, the central market question remains the same: whether sodium-ion can deliver a durable cost and performance advantage fast enough to convert rapid demand growth for AI-linked electricity consumption into large-scale battery adoption.
