Battery demand from electric trucks more than doubled worldwide in 2025, making heavy-duty vehicles the fastest-growing segment in the global EV battery market. The International Energy Agency attributed the surge largely to a sharp acceleration in China, where fleet purchases and policy support drove electric truck sales to more than double their 2024 levels. Trucks now account for about 8 percent of all EV battery deployment globally, a share that carries outsized weight because each truck pack dwarfs a passenger car battery by several times over.
Why the truck battery surge carries weight beyond the headline number
A doubling in truck battery demand is not the same as a doubling in car battery demand. Commercial trucks require packs that can range from 200 to over 600 kilowatt-hours, compared with roughly 60 to 80 kWh for a typical passenger EV. That means even a modest increase in truck unit sales translates into disproportionately large demand for lithium, nickel, cobalt, and other battery-grade minerals. The IEA’s analysis of electric-vehicle batteries found that trucks reached about 8 percent of worldwide EV battery deployment in 2025, up from a smaller share in prior years, despite trucks representing a far smaller fraction of total EV unit sales.
China was the primary engine behind the growth. The majority of global electric truck sales gains in 2025 came from Chinese manufacturers and fleet operators, according to the IEA’s assessment. That concentration raises a specific question about mineral supply chains: will the truck-driven spike in battery consumption force a measurable increase in China’s lithium-carbonate imports? A working hypothesis holds that the 2025 doubling could produce a 15 to 20 percent rise in China’s lithium-carbonate imports for battery use within 18 months, a shift large enough to show up in official customs data. No IEA or customs source has confirmed that projection, so it remains an untested inference rather than a verified forecast. But the direction of pressure is clear: bigger packs, faster adoption, and heavy geographic concentration all point toward tighter raw-material flows.
IEA data and the reclassification factor behind the doubling
The core evidence comes from the IEA’s flagship annual report, released as the latest global EV outlook. Its battery chapter states that truck battery demand more than doubled year on year, the sharpest increase among all vehicle modes tracked. The report’s main narrative explains that this growth in battery deployment closely mirrors the doubling of electric truck sales in 2025 versus 2024, indicating that higher volumes rather than only larger pack sizes drove the change.
The accompanying executive summary separately confirms that electric truck sales more than doubled in 2025 compared with 2024, aligning unit growth with the surge in battery demand. That cross-reference is important because it links the battery-side statistics to the underlying vehicle market, reducing the risk that the doubling is merely an artifact of methodology or partial data.
One definitional change still matters for interpreting the numbers accurately. The IEA reclassified delivery vans into the medium-freight truck category, which lifted the 2025 truck figures relative to earlier editions that counted some of those vehicles differently. The agency’s discussion of trends in non-car EV segments notes that this reclassification affects comparability with past data, and readers comparing 2025 truck statistics with the historical time series should account for it. The IEA publishes a downloadable dataset covering EV battery demand by mode from 2018 through 2024, but the granular 2025 truck figures have not yet appeared in machine-readable form. That means independent analysts cannot yet calculate the exact gigawatt-hour total for 2025 truck batteries or verify the year-on-year percentage with precision.
The prior year’s edition, the Global EV Outlook 2025, showed that truck battery demand was already growing in 2024 but at a pace well below the 2025 rate. The jump from 2024 to 2025 therefore represents a genuine acceleration, not simply a continuation of an existing trend. China’s dominance in the 2025 data is consistent with its broader lead in EV manufacturing and domestic fleet electrification, but the IEA report does not name specific companies, models, or provincial programs behind the Chinese truck surge. That absence limits the ability to tie the growth to particular procurement campaigns or technology platforms.
Gaps in the data and what to watch through 2027
Several pieces of the puzzle are still missing. The IEA has not published a granular breakdown of battery chemistry shifts specific to trucks. Lithium iron phosphate cells dominate the Chinese market for passenger EVs, but whether the same chemistry split applies to heavier commercial vehicles at scale is not addressed in the 2026 report. Chemistry mix matters because it determines which minerals face the tightest supply pressure and which refining bottlenecks could emerge. If high-nickel chemistries hold a larger share in trucks than in cars, for instance, nickel and cobalt supply would feel more direct pressure than lithium alone.
Company-level and model-level sales data behind the Chinese truck surge are also absent from the IEA’s published chapters. Without that detail, it is difficult to assess whether the growth is broad-based across dozens of manufacturers or concentrated among a handful of state-backed fleet operators making bulk purchases. Concentrated demand would be more vulnerable to policy shifts or subsidy changes than widely distributed adoption. A single large municipal tender or logistics-company contract that expires or is delayed could noticeably dent year-on-year comparisons if the underlying market remains narrow.
Direct statements on 2025 mineral demand impact or battery material price effects do not appear in the IEA text. That leaves the connection between truck battery growth and raw-material markets as an analytical inference rather than a documented finding. China’s General Administration of Customs publishes monthly trade data that could eventually confirm whether lithium-carbonate imports rose in line with the hypothesized 15 to 20 percent range following the 2025 truck boom. Analysts will be watching not only aggregate lithium volumes but also shifts in the balance between carbonate and hydroxide, which can hint at changing chemistry choices in downstream cell production.
Another gap concerns regional spillovers. The IEA report emphasizes China’s central role in 2025 but offers less detail on whether supply-chain tightness in Chinese truck batteries is already influencing prices or availability in other regions. If Chinese cell producers divert capacity toward domestic truck contracts, that could constrain exports to Europe or emerging markets, even if global mineral supply remains adequate on paper. Conversely, if overseas truck adoption lags and Chinese manufacturers rely heavily on exports to sustain growth, any trade policy friction could quickly feed back into battery deployment figures.
Through 2027, several indicators will help clarify whether the 2025 doubling represents a one-off spike or the start of a structurally higher growth path. First, updated IEA datasets with disaggregated 2025 and 2026 truck battery demand will allow for more precise gigawatt-hour comparisons and for separating the effects of reclassification from underlying market expansion. Second, customs and trade statistics will show whether China’s imports of lithium and other key battery minerals are rising in step with truck deployment, or whether domestic refining, recycling, or alternative chemistries are offsetting some of the raw-material pull.
Third, policy developments in China and other major markets will shape the durability of the trend. If national and local governments extend or expand incentives for zero-emission freight vehicles, the economics of electric trucks could remain favorable even if battery prices stabilize or rise modestly. On the other hand, any rollback of support, or a shift toward hydrogen or other low-carbon options for heavy-duty transport, could temper the pace of battery demand growth. The IEA’s future editions will likely devote more space to these policy dynamics as governments refine their freight decarbonization strategies.
For now, the 2025 data underline a simple but consequential point: heavy-duty vehicles, though still a minority of EVs on the road, are beginning to punch above their weight in the battery market. Each additional electric truck carries a battery pack that can equal several cars’ worth of cells, magnifying the impact of fleet procurement decisions and policy nudges. As more detailed statistics emerge over the next two years, they will determine whether this first doubling in truck battery demand marks a new normal for mineral markets and supply chains-or an early, volatile chapter in the broader story of electrified freight.
