Overview of Required Battery Passport Information

The battery passport covers four main information clusters:

• General battery and manufacturer information
• Compliance, labels, and certifications
• Battery materials and composition
• Circularity and resource efficiency

Together, these attributes enable authorities, business partners, and end‑users to trace a battery’s origin, assess its safety and environmental profile, and support reuse and recycling strategies.

🧾 General Battery and Manufacturer Information

This part of the battery passport ensures clear identification and traceability of each battery and its manufacturer.

🔍 Identification and Traceability

Key elements include:

• Battery passport identification – a unique identifier for each individual battery that links to its digital passport.
• Battery identification – model designation plus batch, serial, or product number, or any other element that allows precise identification.
• Responsible economic operator identification – name, trade name or mark, postal and web address, e‑mail contact, and a unique operator identifier for the company responsible on the EU market.
• Manufacturer identification – unambiguous identification of the battery manufacturer via a unique operator identifier.
• Manufacturing date and place – at least the month and year of manufacture and a clear indication of the manufacturing facility (for example, country, city, street, building or a dedicated facility identifier).

⚙️ General Battery Characteristics

To support appropriate use, logistics, and end‑of‑life treatment, the passport also records:

• Battery category – the intended use of the battery (for example, traction, stationary storage, light means of transport).
• Battery weight – mass of the entire battery in kilograms; where relevant, the weight of modules or cells within a pack.
• Battery status – lifecycle status such as “original,” “repurposed,” “reused,” “remanufactured,” or “waste.”

🛡️ Compliance, Labels and Certifications

A second group of EU battery passport requirements concerns regulatory conformity and product markings.

📜 Conformity Documentation

The passport should capture:

• EU Declaration of Conformity – confirmation by the responsible economic operator that the battery meets all applicable EU regulatory requirements.
• Identification number of the EU Declaration of Conformity – especially where linked to the battery’s carbon footprint declaration.
• Results of test reports – outcomes of tests demonstrating compliance with technical documentation, safety standards, and due‑diligence policies.

🧾 Symbols and Regulatory Marks

To support safe handling and recycling, the following information is required:

• Separate collection symbol – the crossed‑out wheeled bin or equivalent symbol indicating mandatory separate collection; the meaning should also be represented in text for machine readability.
• Meaning of labels and symbols – explanations of all safety, environmental, and collection symbols placed on the battery.
• Cadmium and lead symbols – symbols indicating the presence of cadmium or lead above specified thresholds, again mirrored in text for digital use.

⚙️ Battery Materials and Composition

Transparency on chemical composition is central to both safety and sustainability of batteries.

🧪 Materials Information

The passport records:

• Critical raw materials – economically important materials vulnerable to supply disruption, listed when present above 0.1 percent by weight.
• Battery chemistry – overall composition, specifying cathode and anode types and the electrolyte system.
• Names of cathode, anode, and electrolyte materials – using publicly recognised nomenclature and linked to the relevant component.
• Chemical identifiers – such as CAS numbers for cathode, anode, and electrolyte materials.
• Mass fractions – percentage by mass of each named material in the respective component.

☣️ Hazardous Substances

For substances of concern, the passport must also contain:

• Names of hazardous substances present above 0.1 percent by weight.
• Hazard classes and categories in line with the Classification, Labelling and Packaging (CLP) Regulation.
• Regulatory identifiers – CAS numbers and CLP index numbers.
• Location in the battery – mapping hazardous substances to components or sub‑components via unique identifiers.
• Concentration ranges – percentage ranges per component.
• Impact statements – information on impacts on human health, safety, and the environment based on REACH or Globally Harmonized System (GHS) classifications.

🌍 Carbon Footprint and Supply Chain Due Diligence

Environmental transparency is further strengthened through:

• Battery carbon footprint – total carbon dioxide equivalent per kilowatt‑hour over the expected service life.
• Share of carbon footprint per lifecycle stage – allocation of emissions to raw material extraction, manufacturing, distribution, and end‑of‑life.
• Carbon footprint performance class – classification of performance per manufacturing plant.
• Web link to the public carbon footprint study – access to supporting life‑cycle assessment documentation.

In addition, companies must document:

• Supply chain due‑diligence report – describing due‑diligence policies, risk‑management processes, and verification activities.
• Third‑party supply chain assurances – certifications or attestations showing conformance with recognised standards.
• EU Taxonomy disclosure statement – information on alignment with the EU Taxonomy, where applicable.
• Sustainability report availability – indication of published sustainability reporting relevant to the battery.

♻️ Circularity and Resource Efficiency

The final group of EU battery passport requirements focuses on enabling repair, reuse, and high‑quality recycling.

🔧 Design for Circularity

To facilitate safe removal and disassembly, the passport should include:

• Manual for removal of the battery from the appliance – describing disassembly sequences, fastener types, required tools, and safety precautions.
• Manual for disassembly and dismantling of the battery pack – detailed instructions, including exploded diagrams and construction details.
• Addresses of spare‑part sources – postal, web, and e‑mail addresses of suppliers.
• Part numbers for components – identification numbers for replaceable parts.

🛡️ Safety Requirements

Information supporting emergency response and safe handling:

• Suitable extinguishing agents – recommended classes of fire extinguishers for the specific battery chemistry.
• Safety measures and instructions – guidelines that reflect past incidents and the actual status or composition of the battery.

🔁 Recycled and Renewable Content

To promote resource efficiency, the passport also documents:

• Pre‑consumer and post‑consumer recycled content – shares of nickel, cobalt, lithium, and lead from recycled sources prior to and after consumer use.
• Renewable content share – percentage of renewable material content in the battery.

🏁 End‑of‑Life Information

End‑of‑life management must be supported by:

• Guidance for end‑users on waste prevention – recommendations for prolonging battery life and encouraging reuse or repurposing.
• Information on separate collection, take‑back, and recycling – locations of collection points and descriptions of recycling operations.

🤝 Preparing for Compliance

Meeting EU battery passport requirements demands accurate technical data, robust supply chain traceability, and well‑structured documentation systems.

Businesses that proactively map the required attributes, assign responsibilities, and integrate data collection into design and manufacturing processes will be better positioned for efficient compliance, smoother market access, and improved sustainability performance.

These structured information obligations help the EU move toward a more transparent, circular battery economy—while enabling manufacturers and other economic operators to demonstrate responsible practices to regulators, customers, and investors, supported by ComplyMarket.
