Market evolution: Lithium batteries (CN 850650) — 2015–2025

Introduction

Lithium cells and batteries (CN 850650) sit at the intersection of the digital economy and the energy transition. Over the decade from 2015 to 2025, the European Union's external trade in this product category underwent a structural transformation driven by three forces: surging demand for portable electronics and electric vehicles, the rapid scale-up of Asian — and especially Chinese — manufacturing capacity, and a series of geopolitical shocks that reshaped trade corridors. This report examines the EU's imports, exports, and production data to trace the main dynamics of this market, highlighting the simultaneous expansion of trade volumes, the divergence in unit prices between import and export flows, and the EU's gradual — though incomplete — shift toward greater self-reliance.

1. A Surge in Volumes, a Collapse in Unit Prices, and a Lingering Deficit

Import volumes grew far more steeply than import values, signaling a dramatic price erosion

Over the period, EU imports of lithium batteries more than doubled in mass, rising from 8,358 tonnes in 2015 to 19,038 tonnes in 2025 (+127.8%). In the same period, the total import value grew by a more modest 59.2%, from €302 million to €482 million. The trade overview makes clear that the explanation lies in the collapse of average import prices, which fell from €36,172 per tonne in 2015 to €25,287 per tonne in 2025 (−30.1%). This trend reflects the global deflationary pressure from mass-scale Asian manufacturing — primarily for consumer electronics and, increasingly, for electric-vehicle battery packs.

Export growth outpaced imports in value but lagged in volume

EU exports grew from €130 million (1,990 tonnes) in 2015 to €247 million (3,512 tonnes) in 2025, corresponding to value and volume increases of +89.5% and +76.5% respectively. Crucially, export unit prices rose slightly over the decade, from €65,340 to €70,249 per tonne (+7.5%). The persistent gap between import and export prices — roughly 2.8:1 in 2025 — indicates that the EU tends to import lower-value commodity cells (often for consumer electronics) while exporting higher-value, more specialised battery products.

The trade deficit persisted and widened in absolute terms

Despite faster value growth on the export side, the EU ran a trade deficit in lithium batteries throughout the entire period:

The deficit peaked around 2022 at −€299 million before narrowing somewhat to −€234 million in 2025. This narrowing owed less to a drop in imports than to a strong acceleration of exports, suggesting that EU-based producers — or at least EU-headquartered firms coordinating production — found expanding markets abroad.

Supplementary-unit data confirms a shift in the product mix

When measured by number of items rather than by weight, EU imports grew from 546 million pieces in 2015 to 977 million in 2025 (+79.1%), while exports grew from 99 million to 139 million pieces (+41.1%). The faster growth in mass-based import volumes relative to piece counts suggests a compositional shift toward heavier batteries — consistent with the growing role of EV battery packs and energy-storage modules alongside traditional small consumer cells.

2. China's Ascendancy and the Increasing Concentration of Import Sources

China became the EU's dominant supplier, more than doubling its share by value

The partner-level data reveals a decisive shift in the EU's import geography. China's shipments to the EU rose from €74 million in 2015 to €162 million in 2025 (+117.7%), making China by far the largest single supplier. In parallel, South Korean imports surged even faster in proportional terms (+240.3%), from €10 million to €33 million. The United States also contributed significantly, rising from €73 million to €124 million (+70.0%), although a substantial portion of these flows likely reflects intra-firm trade by multinational battery or electronics companies.

Import-source concentration increased measurably

The Herfindahl-Hirschman Index (HHI) for EU imports by value rose from 1,614 to 2,016 over the period (+24.9%). An HHI above 1,500 already indicates moderate concentration; the move past 2,000 signals a market whose supply base has become meaningfully less diversified. The main driver was the consolidation of China's position: while the number of major suppliers did not shrink, the weight of the top ones — particularly China and South Korea — grew disproportionately.

The cylindrical cell segment illustrates China's dominance most clearly

The product-segment breakdown shows that imports of cylindrical lithium cells (CN 85065010) surged from 3,300 tonnes (€101 million) in 2015 to 10,651 tonnes (€156 million) in 2025. This threefold increase in mass accompanied by only a 54% increase in value implies that the average price per tonne for this sub-product fell from €30,475 to just €14,617 (−52%). Cylindrical cells — widely used in consumer electronics and increasingly in e-bikes and power tools — are the product category most exposed to cost competition from large-scale Chinese factories. Meanwhile, the "other" category (CN 85065090), which encompasses prismatic and pouch cells used in EVs and industrial storage, saw its import value rise from €134 million to €229 million (+70.8%) while mass doubled to 4,358 tonnes.

Export destinations diversified in some directions but collapsed in others

The export partner data tells a contrasting story. Exports to the United States surged from €27 million to €57 million (+107.3%), and those to the United Kingdom rose from €28 million to €45 million (+61.0%). The most dramatic swing, however, was the redirection of exports toward Ukraine — from a negligible €0.4 million in 2015 to €16.3 million in 2025 (+4,116.1%). Conversely, exports to Russia collapsed from €6 million to almost zero (−99.9%), reflecting the impact of EU sanctions following 2022.

3. From Dependence Toward Autonomy: EU Production, Specialisation, and Supply-Chain Shocks

Domestic production value expanded dramatically even as piece counts fell

The production data reveals a striking transformation. EU production of lithium primary cells fell from 1.26 billion items in 2015 to 780 million in 2025 (−38.0%). Yet the estimated production value surged from €528 million to €2.64 billion (+398.8%). This apparent paradox is explained by a shift in the product mix: EU manufacturers have moved away from high-volume, low-margin commodity cells (such as button and small cylindrical formats) toward higher-value products — likely including larger-format prismatic and pouch cells for industrial and automotive applications. The increase in value, even as unit volumes declined, implies that the EU's battery industry is climbing the value chain.

Net import reliance decreased substantially, but the EU is not yet self-sufficient

The autonomy indicators show that the EU's net import reliance (imports minus exports, as a share of apparent consumption) declined from 25.7% in 2015 to 9.7% in 2025 (−62.2%). In parallel, trade intensity (total external trade as a share of consumption) fell from 56.9% to 23.7%, and export propensity (exports as a share of production) dropped from 29.3% to 8.8%. These figures indicate that the EU's internal market has become more self-sufficient: a growing share of domestic demand is met by domestic production rather than imports, and a declining share of domestic output is being directed abroad. This is consistent with the build-out of European gigafactories by firms such as Northvolt, ACC, and others, though the data also reflects the fact that imports grew more slowly than domestic production value.

Member-state dynamics reflect a geographically uneven transformation

The reporter-level data shows that France and Germany have been the EU's two largest exporters throughout the period, with France growing from €44 million to €69 million (+57.2%) and Germany from €45 million to €62 million (+38.7%). However, the fastest export growth came from Poland (+475.7%, from €1.7 million to €10 million) and Sweden (+125.6%, from €4.0 million to €9.0 million) — both countries hosting major new battery manufacturing investments. On the import side, Ireland's import bill nearly doubled (to €75 million), driven largely by its large electronics-sector demand, while France's imports surged +139.1%, likely reflecting the ramp-up of domestic EV assembly and the need for imported cells during the transition period before domestic cell production reaches full scale.

The specialisation data for 2025 identifies Romania (RSCA: 0.48), Poland (0.30), France (0.24), Belgium (0.22), and the Netherlands (0.19) as the most specialised EU producers in lithium batteries. Ireland, by contrast, is the least specialised (RSCA: −0.93), confirming its role as a demand centre rather than a production hub.

Supply-chain shocks highlight structural vulnerabilities

The volatility analysis reveals several notable episodes. The most significant shock detected was a 245.7% price spike in EU imports from the United Kingdom in 2021, reflecting post-Brexit supply-chain disruption and the rerouting of trade flows. A second notable event was a 63.2% shift in export prices to China in 2020, coinciding with the early-COVID demand shock. Imports from Indonesia and Malaysia showed the highest overall volatility (coefficients of variation of 1.02 and 1.45 respectively), reflecting the episodic nature of nickel-processing and cell-assembly investments in Southeast Asia. On the export side, flows to Singapore (CV: 1.86) and Ukraine (CV: 1.41) were the most volatile, consistent with the small initial base and the geopolitical circumstances surrounding each.

The concentration analysis also shows that while import-source concentration rose, export-market concentration remained broadly flat (HHI around 1,130–1,140), suggesting that the EU's export base has been more resilient in its diversification than its import supply chain.

Conclusion

The EU's lithium battery market between 2015 and 2025 has been defined by rapid growth in volumes, a structural fall in import prices driven by Asian manufacturing scale, and a persistent — though narrowing — trade deficit. China's position as the dominant supplier has strengthened considerably, and import-source concentration has risen to levels that warrant attention from a supply-security perspective. At the same time, the EU has made tangible progress toward greater autonomy: domestic production value has multiplied nearly fivefold, net import reliance has fallen from over a quarter to under a tenth of consumption, and several member states — particularly Poland, Sweden, and Romania — are emerging as specialised production centres. The ongoing build-out of European gigafactories suggests that this trajectory will continue, though the speed of convergence will depend on investment timelines, raw-material access, and the competitive pace of Asian producers. Geopolitical disruptions — most visibly the collapse of exports to Russia and the surge toward Ukraine — have further underscored the strategic dimension of this market. For policymakers and industry stakeholders, the central challenge for the years ahead will be to sustain the EU's value-chain ascent while managing the concentration risks inherent in a still-import-dependent market.
