2025 Trends and Strategic Insights

Market Momentum Driven by Safety Innovation

The global demand for enhanced battery safety has accelerated across the EV supply chain. As automakers prioritize cell integrity and regulatory bodies tighten standards, nail penetration safety systems have become critical components in battery pack architecture.

The 2025 report underscores a major uptrend in the integration of Copper and Aluminum foil-based safety protections, helping batteries withstand direct puncture events-traditionally among the most dangerous scenarios triggering thermal runaway.

BYD and Samsung Invest in Cell-Level Fire Prevention

In Q2 2025, BYD announced its third-generation blade battery now includes internal structural reinforcement aimed specifically at puncture resistance. Their in-house testing reportedly passed a multi-nail penetration test at 100% SOC (State of Charge) without fire or fume release, positioning BYD as a global safety leader in LFP technology.

Meanwhile, Samsung SDI introduced a new modularized Battery Protection Unit (BPU) embedded with nano-layered foil that activates an instant current cut-off upon nail impact. This system was successfully tested across several platforms in Korea and Europe in early 2025 and is expected to debut in 2026 EV fleets.

China Tightens Regulatory Standards; Europe Follows

The Ministry of Industry and Information Technology (MIIT) of China, in March 2025, released updated safety requirements for EV power batteries. These new standards include mandatory nail penetration testing protocols, cooling redundancy, and physical fire retardant barriers. These rules are now mirrored in pilot programs across Europe under UNECE WP.29 framework.

These regulatory shifts are pushing OEMs and suppliers to invest more in multi-layer protection systems and real-time impact monitoring-trends already visible in products released by Phoenix Contact and IntriPlex this year.

Expanding Use Cases Beyond Passenger Vehicles

Although Passenger Cars accounted for the bulk of demand in 2024, Commercial Vehicles are rapidly adopting nail safety systems, especially in fleet EVs, logistics trucks, and municipal transport. Companies like Cisco and SICK are now offering integrated sensor systems that detect deformation or heat anomalies in battery packs, enabling predictive failure management.

These solutions are particularly relevant in high-mileage applications, where wear-induced vulnerability to nail penetration increases.

Regional Expansion: Asia-Pacific Dominates, Germany Accelerates

The Asia-Pacific region, particularly China, Japan, and South Korea, continues to dominate market share due to vertically integrated battery supply chains and strong EV adoption. The 2025 report highlights that China alone captured a significant percentage of global revenue in 2024 and is expected to increase its share by 2031, driven by national EV targets and fire safety mandates.

Europe, especially Germany, is catching up quickly with major investments in battery innovation hubs. In July 2025, Germany's Federal Ministry for Economic Affairs and Climate Action funded a €160 million initiative for next-gen EV battery testing-including nail safety stress tests-across five regional R&D centers.

Investment in Test Infrastructure

In late 2024, Applus+ IDIADA launched a new battery safety laboratory exceeding 2,000 m2, capable of simulating nail penetration, crush, and fire scenarios. This facility has since attracted collaborations with CATL and OsecoElfab for advanced safety certification in global markets.

These investments underscore a growing emphasis on test validation, with automotive OEMs requiring component-level certification before system integration.

Strategic Outlook to 2031

The report's industry-chain analysis reveals increasing complexity across upstream material sourcing (foil composites, smart vents), middlestream integration (module assembly), and downstream adoption (OEM and aftermarket systems). This multilayered value chain offers opportunities for both consolidation and innovation.

The highest-margin product segments are expected in modular safety foils and predictive thermal safety modules, where revenue per unit is highest. With market leaders such as H&T Battery Components and CATL continuing to expand production in this space, the competitive landscape is likely to consolidate around vertically integrated suppliers with IP-protected solutions.
