Battery Pack Market (2026-2036)

The growth of this market is mainly driven by rising electric vehicle production, rapid expansion of stationary energy storage deployment supported by grid modernisation and data centre power requirements, the adoption of cell-to-pack and cell-to-chassis architectures that increase energy density, continued localisation of battery manufacturing under industrial policy incentives, and the extension of lithium-ion packs into commercial vehicles, off-highway equipment, marine and aviation applications. However, sustained declines in pack prices per kilowatt-hour, severe margin pressure and overcapacity across the cell manufacturing base, raw material price volatility, and safety and transport regulation restrain the growth of this market.

Furthermore, the growth of stationary storage for artificial intelligence data centres, the commercialisation of sodium-ion and solid-state pack designs, the emergence of replacement and second-life pack markets as the electric vehicle fleet ages, and the standardisation of pack interfaces for swapping and modular assembly are expected to create significant growth opportunities for the stakeholders in this market.

The Battery Pack Market comprises complete assembled battery packs supplied for automotive, stationary storage, consumer, industrial, medical and defence applications. A pack integrates electrochemical cells with a battery management system, a thermal management system, a structural enclosure, busbars and interconnects, wiring harnesses and connectors, current and temperature sensors, and safety and disconnect devices including contactors, fuses and pyrotechnic disconnects. The market scope therefore covers the value of the cells together with all pack-level components, assembly and testing, and it includes module-based, cell-to-pack, cell-to-chassis and containerised rack-based configurations. The ecosystem includes active and inactive cell material producers, cell manufacturers, battery management system and power electronics suppliers, thermal system and coolant plate suppliers, enclosure and structural component manufacturers, connector and busbar suppliers, pack assembly operations run by cell makers, vehicle manufacturers and contract assemblers, system integrators in stationary storage, and recycling and second-life operators.

Demand is determined by the volume of electrified equipment produced and by the energy content installed in each unit. According to the International Energy Agency, global electric car sales exceeded 20 million units in 2025, an increase of approximately 20% over 2024 and representing approximately 25% of new car sales worldwide. More than 13 million electric cars were sold in China, representing approximately 55% of new car sales in that market, against approximately 4.2 million in Europe at 28% of new car sales and approximately 1.5 million in the United States at just below 10%, with United States volumes slightly below 2024. Adding commercial electric vehicles, electric two and three-wheelers, stationary storage installations, consumer electronics and industrial equipment, global pack shipments are estimated at approximately 1,905 GWh in 2025.

Pack manufacturing is concentrated among a small number of very large producers. CATL reported 2025 operating revenue of RMB 423.7 billion, up 17%, net profit of RMB 72.2 billion, up 42%, total battery sales of 661 GWh, up 39%, and research and development spending of RMB 22.1 billion, alongside a 30.4% global energy storage market share across 2,300 projects. That sales volume represents approximately a third of estimated global pack shipments in 2025. LG Energy Solution reported 2025 consolidated revenue of KRW 23.7 trillion, down 7.6%, with operating profit of KRW 1.3 trillion at a 5.7% margin that included the North American production incentive, and fourth-quarter revenue of KRW 6.1 trillion, up 7.7% on the preceding quarter, with a fourth-quarter operating loss of KRW 122 billion that included a North American production incentive of KRW 332.8 billion. Samsung SDI reported 2025 revenue of KRW 13.27 trillion with an operating loss of KRW 1.72 trillion, and fourth-quarter revenue of KRW 3.86 trillion, up 26.4% on the preceding quarter, with an operating loss of KRW 299.2 billion that was approximately half the loss recorded in the third quarter.

These results describe a market in which volume growth and financial performance have diverged. Cell and pack capacity installed across China, Korea, Japan, Europe and North America now exceeds demand in several chemistry and format categories, and competition for programme awards has driven pack prices per kilowatt-hour down sharply. The blended global pack price is estimated at approximately USD 86 per kilowatt-hour in 2025, with lithium iron phosphate automotive packs produced in China at materially lower levels and nickel-rich packs produced in Western markets at materially higher levels. Revenue growth for pack suppliers has consequently lagged volume growth, and margins have narrowed to the point where several large producers have recorded operating losses despite rising shipments.

Stationary energy storage has become the strongest source of demand growth. Tesla deployed 46.7 GWh of energy storage in 2025, including a record 14.2 GWh in the fourth quarter, against vehicle production of 1,654,667 units and deliveries of 1,636,129 units. LG Energy Solution reported an energy storage order backlog of 140 GWh at the end of 2025, with energy storage production capacity set to exceed 60 GWh in 2026 and more than 80% of that capacity located in North America, and began local production of lithium iron phosphate storage batteries in the region. Samsung SDI reported record quarterly energy storage revenue in the fourth quarter of 2025 and stated that the outlook for energy storage batteries is considerably stronger than for electric vehicle batteries, citing artificial intelligence data centres, power storage, uninterruptible power supply and battery backup unit applications as the principal drivers. Grid-scale installations account for approximately 95% of energy storage demand in North America.

Pack architecture is changing in ways that alter the composition of market value. Module-based designs, in which cells are assembled into modules and modules into packs, remain the installed standard but are being displaced by cell-to-pack designs that mount cells directly into the pack enclosure, and by cell-to-chassis and structural pack designs in which the pack enclosure forms part of the vehicle body. Each step removes intermediate structure, raises volumetric energy density and reduces part count, which lowers pack-level cost per kilowatt-hour while increasing the share of pack value accounted for by the cells themselves. The trend is reinforced by the shift toward lithium iron phosphate chemistry, whose lower energy density at cell level is partly offset by denser pack packaging, and by large-format cells including the 46-series cylindrical format. LG Energy Solution reported a 46-series cylindrical order backlog of more than 300 GWh at the end of 2025, and Samsung SDI reported agreements to supply nickel-cobalt-aluminium 46-series cells to leading automotive customers.

Chemistry selection now varies by application rather than following a single trajectory. Lithium iron phosphate has become the dominant automotive chemistry by volume in China and is expanding in Western markets and in stationary storage, where cycle life and cost matter more than energy density, and Samsung SDI is pursuing United States production of prismatic lithium iron phosphate storage blocks. Nickel-rich chemistries retain premium automotive applications requiring range and fast charging, while lithium manganese iron phosphate occupies an intermediate position. Sodium-ion is entering commercial production for stationary storage, low-cost vehicles and cold-climate applications. Solid-state designs remain pre-commercial, and Samsung SDI has entered a joint development agreement with BMW to validate all-solid-state battery technology. Each chemistry requires different thermal management, state-of-charge estimation and safety engineering at pack level.

Industrial policy is a principal determinant of where packs are assembled. Production incentives in the United States materially affect reported profitability, and LG Energy Solution recorded a North American production incentive of KRW 332.8 billion in the fourth quarter of 2025 against a quarterly operating loss of KRW 122 billion, which indicates that the incentive exceeded the underlying operating result. The company also stated that more than 80% of its energy storage capacity will be located in North America in 2026 and that maintenance of the clean energy investment tax credit supports that positioning. European and Indian localisation requirements, Chinese export controls and local content rules in several emerging markets are likewise directing capacity placement. Because packs are heavy, bulky and classified as dangerous goods for transport, assembly close to the point of installation is in any case preferable, which reinforces the policy effect.

Safety and transport regulation shapes pack design and certification cost. Packs must satisfy abuse and propagation requirements under United Nations Regulation No. 100, transport requirements under the UN Manual of Tests and Criteria section 38.3, and system-level requirements under IEC 62619 and UL 1973, with UL 9540 and UL 9540A governing energy storage systems and thermal runaway propagation testing, and NFPA 855 governing installation spacing and protection. These requirements determine enclosure construction, venting, propagation barriers and suppression provisions, and they add certification time and cost to every new design, which favours suppliers able to reuse qualified platforms across programmes.

Competition spans cell manufacturers that also assemble packs, vehicle manufacturers that have integrated pack assembly, specialist assemblers and system integrators. CATL, BYD, LG Energy Solution, Samsung SDI, SK On, Panasonic Energy, CALB, EVE Energy, Gotion High-Tech and Sunwoda supply cells and in most cases complete packs. Vehicle manufacturers including Tesla, BYD, Volkswagen and Hyundai assemble packs in-house to control cost and integration. Stationary storage integrators including Tesla, Sungrow, Fluence and BYD supply containerised systems combining packs with power conversion and controls, while specialist suppliers provide battery management systems, thermal plates, enclosures, busbars, connectors and safety devices into all of these channels. The boundary between cell supplier, pack assembler and system integrator therefore differs by region and application.

Over the forecast period, market value is expected to grow at roughly half the rate of shipment volume. Pack shipments are expected to rise from approximately 1,905 GWh in 2025 to approximately 5,930 GWh in 2036, an increase of more than three times, while the blended pack price declines from approximately USD 86 per kilowatt-hour to approximately USD 58 per kilowatt-hour as cell chemistry, manufacturing scale, pack architecture and manufacturing yield continue to improve. The principal uncertainties are the pace of electric vehicle adoption in North America, where 2025 volumes of approximately 1.5 million units were slightly below 2024 levels, the durability of stationary storage demand growth driven by data centre and grid requirements, the extent and duration of overcapacity in cell manufacturing, and whether industrial policy support in the United States, Europe and India is sustained at levels that justify the localised capacity already committed.
