Asia and Europe Lead the Next Wave of Cell-to-Pack Scaling as OEMs Push for Lower-Cost, Localized LFP Ecosystems

Asia and Europe Accelerate CTP Adoption to Localize Cost-Competitive LFP Supply Chains

In Asia, the rapid scale-up of Cell-to-Pack (CTP) technology is being driven by major cell manufacturers (CATL, BYD) utilizing fully automated production lines and vertical integration (cell → pack → vehicle). This structure significantly shortens lead times and lowers costs, particularly favoring LFP pouch/blade formats due to their simplified, moduleless design which enhances automation and volumetric efficiency. Meanwhile, Europe is also embracing CTP at gigafactory scale, evidenced by deals like LG Energy Solution supplying LFP pouch batteries with CTP solutions for Renault Group’s Ampere production in Poland. European investments and national gigafactory plans are actively funding new cell lines where OEMs and suppliers are piloting CTP approaches to rapidly localize cost-competitive LFP supply chains.

This dual-region momentum reflects a fundamental shift in the EV battery landscape. Asia’s established manufacturing dominance is enabling next-generation CTP platforms to achieve faster commercialization cycles, while Europe’s urgent push for domestic LFP capacity is accelerating technology transfer, pilot line buildouts, and OEM–cell-maker partnerships. Together, these dynamics signal a major inflection point where CTP becomes a mainstream architecture for mid-range EVs, commercial vehicles, and cost-sensitive electric platforms.

1. LG Energy Solution supplying CTP-based LFP pouch batteries to Ampere
   LG Energy Solution is supplying CTP-based LFP pouch batteries to Ampere (a pure-EV brand under Renault Group) for ~39 GWh over five years starting in 2025. The announcement specifically states that the packs will apply “CTP solutions, ensuring enhanced cost competitiveness and safety.” Applying CTP architecture (cells are directly integrated into the pack, without a module) in LFP chemistry aims to reduce cost and complexity/complexity and mid-EV segments.

This partnership is strategically important for Europe. Ampere’s platform strategy requires modular EV architectures that can scale rapidly across affordable segments, and CTP-based LFP delivers precisely that—lower thermal runaway risk, fewer structural components, and up to 10–15% improved volumetric efficiency compared with module-based packs. The move also strengthens Renault Group’s long-term localization plan, reducing reliance on Asia-based LFP suppliers.

   The upgraded ‘S-Pack+’ with SK On's Cell-to-Pack (CTP) technology … cost reduction through simplified manufacturing processes and optimized product design. SK. Demonstration of CTP pack technology that integrates module functions into the pack and reduces part-count, aimed at broader EV applications.

SK On’s S-Pack+ reveals how Korean manufacturers are preparing to scale CTP beyond premium EVs into mainstream passenger cars and commercial fleets. The platform’s design simplification aligns with the industry trajectory toward structural packs, reduced wiring harnesses, and lower pack-level overhead—core requirements for improving EV affordability.

Regional CTP Expansion: Program Snapshots

Cell to Pack - region-specific programs

What These Programs Indicate About Market Direction

This wave of CTP deployments across Asia and Europe highlights several major shifts shaping the next phase of EV battery innovation:

• CTP is becoming the standard for LFP-based EVs, particularly for cost-optimized segments where module removal provides the greatest savings.

• Pouch and soft-pack CTP formats are gaining ground due to their compatibility with automation and their ability to increase energy density on a pack basis.

• Gigafactory-scale CTP lines are now commercially operational, not just pilot programs—especially in China.

• OEM–cell maker alliances are accelerating, with long-term supply contracts tied directly to next-gen CTP pack designs.

• Europe’s localization drive is narrowing the cost gap with Asia, especially through LFP gigafactory investments and CTP-specific manufacturing lines.

Strategic Implications for the Global EV Ecosystem

CTP is transitioning from an innovation differentiator to an industry-standard architecture that:

• Reduces pack cost by eliminating modules
• Improves volumetric efficiency and structural integrity
• Enhances manufacturing automation
• Enables OEMs to simplify platform design for mass-market EV rollouts
• Strengthens regional supply chain resilience, particularly for LFP batteries

As Asia leads with scale and Europe accelerates with localization programs, the global Cell-to-Pack Battery Market is entering its most significant adoption phase yet. CTP will be central to enabling affordable EVs, securing domestic supply chains, and setting new benchmarks for cost, safety, and efficiency across next-generation electric platforms.
