WHY THIS MATTERS
- Global EV battery deployment reached 1.2 TWh in 2025, almost 30% higher than in 2024.
- Electric trucks were the fastest-growing segment, with battery demand more than doubling and accounting for about 8% of global EV battery deployment, up from less than 5% in 2024.
- At the same time, the battery landscape is diversifying.
- LFP is emerging as the cost-conscious workhorse.
- LMFP seeks to push LFP towards greater energy density.
- Sodium-ion offers a lithium-free alternative with particularly strong low-temperature performance.
- Solid-state is pursuing the next major step in energy density and safety, although its advantages still need to be demonstrated at scale.
- The question is therefore no longer simply: Which battery is best?
- It is becoming: Which battery is best for which mission?
THE END OF ONE-SIZE-FITS-ALL
For the first generation of electric vehicles, lithium-ion dominated the conversation. Now the chemistry landscape is becoming more diverse. NMC, LFP, LMFP, sodium-ion and solid-state technologies are progressing at different speeds and with different objectives. Messe Frankfurt's latest industry analysis highlights how this diversification is already changing the technical requirements surrounding electric vehicles.
For commercial vehicles, that diversification could become particularly important. A truck is not simply a larger passenger car. Its battery must deliver energy over long duty cycles, often under high loads, while protecting payload, uptime and operating economics. The future may therefore not belong to a single winning chemistry. It may belong to purpose-built battery strategies.
LFP BECOMES THE WORKHORSE
Lithium iron phosphate — LFP — has moved from alternative chemistry to mainstream technology. The IEA reports that LFP accounted for more than 55% of global EV battery deployment in 2025, up from nearly 50% in 2024. Its growth has been particularly strong in China and emerging markets. Its attraction is clear. LFP avoids nickel and cobalt, offers strong thermal stability and can provide long cycle life. It also has a significant cost advantage over nickel-rich chemistries.
The IEA reports that LFP battery packs were more than 40% cheaper per kWh on average than NMC alternatives in 2025, although the comparison is influenced by differences in application and energy-density requirements.
For commercial vehicles, that combination is compelling.
- Lower cost.
- Long cycle life.
- Thermal stability.
- Reduced dependence on nickel and cobalt.
But there is a trade-off. LFP has lower energy density than NMC. And in a commercial vehicle, battery mass is not simply a technical specification. It can become part of the payload equation.
LMFP PUSHES THE ENVELOPE
The next development is lithium manganese iron phosphate — LMFP. It builds on the LFP chemistry while introducing manganese to improve energy density. According to industry reports, LMFP can provide approximately 15% higher energy density than current LFP, potentially allowing more range from a similarly sized battery pack. For commercial vehicles, even incremental gains can matter.
More energy density could mean:
- More range from the same pack.
- Or: Less battery mass for the same range.
Either could improve the economics of electric freight. The attraction of LMFP therefore lies in evolution rather than revolution. It seeks to preserve many of LFP's strengths while narrowing one of its most important disadvantages.
SODIUM-ION ENTERS THE RACE
Sodium-ion takes a fundamentally different route. Instead of relying on lithium, it uses sodium — an abundant element with potential supply-chain advantages. Its strongest technical advantage is particularly interesting for commercial vehicles operating in cold climates. The IEA reports that the latest sodium-ion batteries can retain around 90% of nominal capacity at temperatures as low as −40°C, while operating at temperatures as high as 70°C. That could matter for vehicles operating in northern Europe, Canada and other cold-weather environments.
But sodium-ion has a significant limitation. The latest cells can reach up to approximately 175 Wh/kg, compared with up to 205 Wh/kg for LFP and 265 Wh/kg for NMC, according to the IEA. Lower energy density limits its appeal for applications where maximum range and payload efficiency dominate. The IEA therefore sees sodium-ion as particularly suited, at least initially, to smaller-range vehicles, light commercial vehicles in urban operations, industrial equipment and stationary storage, while hybrid battery configurations could also help address cold-weather performance.
That suggests an important possibility: Sodium-ion may complement lithium-ion rather than replace it.
SOLID-STATE CHANGES THE EQUATION
Then comes the technology attracting perhaps the greatest attention. Solid-state batteries replace the conventional liquid electrolyte with a solid electrolyte. The potential prize is substantial. Solid-state technology promises higher energy density and enhanced safety, potentially making it particularly relevant to applications where battery weight is a major constraint. The IEA specifically identifies long-haul electric trucks among the sectors that could benefit from higher-energy-density technologies such as solid-state batteries.
Initial small-scale production programmes are being targeted by several manufacturers from 2027 onwards, including BYD, Toyota and QuantumScape.
Solid-state is promising. It is not yet proven at commercial scale. The IEA cautions that the claimed advantages in range and safety still need to be demonstrated in real-world applications and at scale. Cost is another barrier. Early solid-state applications are therefore more likely to appear in premium or high-value vehicles before the technology becomes economically viable across mass-market commercial transport. For long-haul trucking, the opportunity is enormous. But so is the engineering challenge.
THE PAYLOAD EQUATION
For passenger cars, additional battery mass may be inconvenient. For commercial vehicles, it can directly affect the business model. A truck earns money by moving cargo. If a heavier battery reduces available payload, the operator may need to make more journeys or accept lower payload efficiency. This makes specific energy — Wh/kg — particularly important for long-haul electric trucks.
But energy density is not the only variable. A cheaper, longer-lasting battery may deliver a better total cost of ownership even if it stores less energy per kilogram. The commercial-vehicle battery race therefore has a different finish line: Not maximum performance; but, maximum useful productivity.
DIFFERENT MISSIONS. DIFFERENT BATTERIES.
Consider four operating environments.
URBAN DELIVERY
- Short routes. Frequent stops. Depot charging.
- LFP or sodium-ion could be particularly attractive.
REGIONAL DISTRIBUTION
- Moderate range. High daily utilisation. Fast turnaround.
- LFP or LMFP could offer a strong balance.
LONG-HAUL FREIGHT
- Long distances. High payload sensitivity. Minimal charging downtime.
- Higher-energy-density technologies become increasingly valuable.
COLD-CLIMATE OPERATIONS
- Low temperatures. Range degradation becomes a critical concern.
- Sodium-ion's low-temperature performance becomes particularly interesting.
These are not predictions of market winners. They illustrate the underlying principle: battery chemistry could increasingly be selected according to duty cycle.
THE GLOBAL BATTERY EQUATION
Battery technology is also a supply-chain question. The IEA reports that China accounted for more than 80% of global battery-cell production in 2025, while also dominating key parts of the battery materials chain. LFP is particularly concentrated. The IEA says production of LFP cathode materials and their precursors remains almost entirely concentrated in China.
Sodium-ion offers a potential route towards reducing dependence on lithium. But it does not automatically eliminate supply-chain concentration. The IEA notes that sodium-ion manufacturing capacity remains much smaller than lithium-ion capacity, with the supply chain for hard carbon — a key anode material — still poorly developed and largely concentrated in China.
This creates a paradox. A new chemistry can diversify raw materials without necessarily diversifying manufacturing. For commercial-vehicle manufacturers planning products with operating lives measured in years, that distinction matters.
THE COMMERCIAL VEHICLE FUTURE
The next decade of electric trucking is unlikely to be defined by one dramatic battery breakthrough. It will probably be defined by specialisation. LFP could remain the dependable workhorse. LMFP could push affordable lithium-ion technology towards greater range. Sodium-ion could find niches where cold-weather performance, cost and reduced lithium dependence matter. Solid-state could eventually redefine high-range electric mobility.
Alongside chemistry, improvements in thermal management, cell-to-pack architecture, charging technology, battery software and recycling will influence the final outcome.
The transformation is therefore not simply:
Lithium-ion → Solid-state.
It is: one battery architecture → A portfolio of purpose-built energy systems.
THE BATTERY IS BECOMING THE MISSION
This may ultimately be the most important change. Today, battery selection is often discussed as a question of chemistry. Tomorrow, fleet operators may think about it in terms of mission architecture. A delivery truck may need affordability and cycle life. A regional haulier may value energy density and fast charging. A long-haul tractor may prioritise payload preservation and range. A cold-climate operator may value temperature resilience. The battery therefore becomes more than an energy store. It becomes part of the vehicle's operating strategy.
MOBILITY ANSWERS
1.Will solid-state batteries replace LFP?
Not necessarily. LFP is already a mainstream chemistry with strong cost and deployment advantages, while solid-state remains in the scale-up and demonstration phase.
2.Why is LFP important for commercial vehicles?
Its combination of cost competitiveness, thermal stability and long cycle life makes it attractive for many applications. Its lower energy density can, however, be a disadvantage for weight-sensitive long-haul operations.
3.Where could sodium-ion batteries make sense?
Their low-temperature performance and reduced dependence on lithium make them particularly interesting for cold climates, urban vehicles, light commercial vehicles and selected industrial applications. Their lower energy density remains a constraint.
4.Why does solid-state matter to electric trucks?
Higher energy density could potentially reduce the mass and packaging burden associated with large battery packs. The technology therefore has particular relevance to long-haul applications — but its cost, durability and large-scale manufacturing performance still need to be demonstrated.
5.Will there be one dominant battery chemistry?
Probably not across every commercial-vehicle application. Duty cycle, payload, climate, charging availability, vehicle cost and total cost of ownership could increasingly determine which chemistry makes the most sense.

ELECTRIC TRACK PERSPECTIVE
The most important battery of the future may not be the best battery. It may be the battery that is best suited to the job. For commercial vehicles, that is a profound shift.
A city truck does not have the same energy requirements as a long-haul tractor. A refrigerated vehicle has different thermal demands from a parcel van. A vehicle operating in Scandinavia faces a different environment from one working across the Gulf. The battery therefore becomes part of the vehicle's mission architecture. And that changes the conversation.
The future of electric commercial mobility may not belong to a single chemistry. It may belong to intelligent matching — the right chemistry, energy density, thermal strategy and charging architecture for the right vehicle, route and duty cycle. That is where the battery race becomes a mobility strategy.
THOUGHT TO TAKE AWAY
The future of electric mobility will not be powered by one perfect battery, but by the right battery for every mission.
