Call content
short description
Proposals are expected to target technologies for design-to-cost batteries, with little reliance on Critical Raw Materials (CRM), from one of the following two main technologies:
- Liquid electrolyte lithium-ion batteries with lithium manganese iron phosphate (LMFP) or manganese-rich HLM (high lithium, manganese) as cathode materials (design-to-cost lithium-ion batteries for mobility);
- Sodium-ion batteries for mobility applications.
Call objectives
Project results are expected to contribute to all of the following outcomes:
- Development of next generation low-cost batteries for improving the affordability of electric mobility, enhancing the competitiveness of the European battery value chain, while lowering the share of Critical Raw Materials (CRM);
- Improved adaptation and flexibility of advanced and sustainable production processes in European battery manufacturing;
- Improved adaptation/flexibility of design-to-circularity strategies.
Expected effects and impacts
The projects are expected to demonstrate, at the end of the project, the following:
For HLM and LMFP chemistries, at the cell level:
- Gravimetric energy density and volumetric energy density of at least 220 Wh/kg (for LMFP) and 250 Wh/kg (for HLM) and 550 Wh/L (for both) at operational temperature, respectively;
- Charging duration of 20 minutes (20-80% SoC);
- Cycle life of >4000 cycles for LMFP and >1500 cycles for HLM at 80% depth of discharge;
- Electric Vehicle (EV) grade cell format and capacity;
- A feasible pathway towards a competitive cost of 50-75€/kWh at pack level by 2030.
For sodium-ion batteries at cell level:
- Gravimetric energy density and volumetric energy density of 180-200 Wh/kg and 400+ Wh/L at operational temperature, respectively;
- Cycle life of 4000-6000 cycles at 80% depth of discharge;
- Charging duration of 20 minutes (20-80% SoC);
- EV grade cell format and capacity;
- A credible pathway towards a competitive cost level of 50-75€/kWh at pack level by 2030.
Projects are expected to demonstrate the production of cell prototypes at pilot level and feasibility of compatibility (or improvement) of the developed materials with regards to at least one of the following cell production processes:
- Dry or aqueous processing technologies;
- Advanced electrode drying processes;
- Improved cell formation processes and aging protocols;
- Improved energy efficiency of processes in dry rooms.

Expected results
Proposals are expected to provide the corresponding state-of-the-art benchmark for the selected production process and compare the project’s compatibility or improvement targets to said benchmark.
Furthermore, projects are expected to demonstrate the feasibility of compatibility (or improvement) of the developed materials with regards to at least one of the following:
- Design for sorting, dismantling, separation, cost-effective repairing/regeneration, and safe recycling (including direct recycling);
- Adapting Sensing solutions to improve lifetime and state of health detection;
- Quantification of degradation mechanisms at early stage to determine the best strategy for beyond the first life.
The Commission initiative for Safe and Sustainable by Design (SSbD) sets a framework for assessing the safety and sustainability of chemicals and materials which should be considered as a reference for project proposals.
Whenever the expected exploitation of project results entails developing, creating, manufacturing and marketing a product or process, or in creating and providing a service, the plan for the exploitation and dissemination of results must include a strategy for such exploitation. The exploitation plans are expected to include preliminary plans for scalability, commercialisation, and deployment (feasibility study, business plan) indicating the possible funding sources to be potentially used (in particular the Innovation Fund).
Proposals could consider the involvement of the European Commission's Joint Research Centre (JRC) whose contribution could consist in providing added value regarding integral evaluation of safety of materials. For further information on the JRC’s possible contribution to the projects, please, search for additional publicly available information on the JRC’s website (EU Science Hub) on the NCP portal, or request specific information from the JRC (JRC-NCP-Network@ec.europa.eu)
JRC shall assure that all the other applicants receive the same information on the JRC’s possible contribution to the project (e.g., via the topic-specific FAQs under the Funding and Tenders Portal).
Projects are expected to collaborate and contribute to the activities of the Coordination and Support Action defined under the topic HORIZON-CL5-2025-D2-02-06.
To strengthen the European battery ecosystem, projects are expected to use materials, products and equipment produced in EU Member States and countries associated to Horizon Europe, unless it is demonstrated that no valid option exists. The procurement strategies should be described in the proposal, especially and to the furthest extent possible the place of production of the elements.
This topic implements the co-programmed European Partnership on Batteries (Batt4EU). As such, projects resulting from this topic will be expected to report on the results to the European Partnership on Batteries (Batt4EU) in support of the monitoring of its KPIs.

Project Partnership
To be eligible for funding, applicants must be established in one of the following countries:
- the Member States of the European Union, including their outermost regions
- the Overseas Countries and Territories (OCTs) linked to the Member States
- countries associated to Horizon Europe - see list of particpating countries
Only legal entities forming a consortium are eligible to participate in actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:
- at least one independent legal entity established in a Member State; and
- at least two other independent legal entities, each established in different Member States or Associated Countries.
Any legal entity, regardless of its place of establishment, including legal entities from non-associated third countries or international organisations (including international European research organisations) is eligible to participate (whether it is eligible for funding or not), provided that the conditions laid down in the Horizon Europe Regulation have been met, along with any other conditions laid down in the specific call topic.
A ‘legal entity’ means any natural or legal person created and recognised as such under national law, EU law or international law, which has legal personality and which may, acting in its own name, exercise rights and be subject to obligations, or an entity without legal personality.
The Joint Research Centre (JRC) may participate as member of the consortium selected for funding.
other eligibility criteria
Specific cases:
- Affiliated entities (i.e. entities with a legal or capital link to a beneficiary which participate in the action with similar rights and obligations to the beneficiaries, but which do not sign the grant agreement and therefore do not become beneficiaries themselves) are allowed, if they are eligible for participation and funding.
- Associated partners (i.e. entities which participate in the action without signing the grant agreement, and without the right to charge costs or claim contributions) are allowed, subject to any conditions regarding associated partners set out in the specific call conditions.
- Entities which do not have legal personality under their national law may exceptionally participate, provided that their representatives have the capacity to undertake legal obligations on their behalf, and offer guarantees to protect the EU’s financial interests equivalent to those offered by legal persons.
- Legal entities created under EU law (EU bodies) including decentralised agencies may be part of the consortium, unless provided for otherwise in their basic act.
- International European research organisations are eligible to receive funding. International organisations with headquarters in a Member State or Associated Country are eligible to receive funding for ‘Training and mobility’ actions or when provided for in the specific call/topic conditions. Other international organisations are not eligible to receive funding, unless provided for in the specific call/topic conditions, or if their participation is considered essential for implementing the action by the granting authority.
- Joint Research Centre (JRC)— Where provided for in the specific call conditions, applicants may include in their proposals the possible contribution of the JRC but the JRC will not participate in the preparation and submission of the proposal. Applicants will indicate the contribution that the JRC could bring to the project based on the scope of the topic text. After the evaluation process, the JRC and the consortium selected for funding may come to an agreement on the specific terms of the participation of the JRC. If an agreement is found, the JRC may accede to the grant agreement as beneficiary requesting zero funding or participate as an associated partner, and would accede to the consortium as a member.
- Associations and interest groupings — Entities composed of members (e.g. European research infrastructure consortia (ERICs)) may participate as ‘sole beneficiaries’ or ‘beneficiaries without legal personality’. However, if the action is in practice implemented by the individual members, those members should also participate (either as beneficiaries or as affiliated entities, otherwise their costs will NOT be eligible.
- EU restrictive measures — Entities subject to EU restrictive measures under Article 29 of the Treaty on the European Union (TEU) and Article 215 of the Treaty on the Functioning of the EU (TFEU) as well as Article 75 TFEU, are not eligible to participate in any capacity, including as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any).
- Legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine — Given the illegal invasion of Ukraine by Russia and the involvement of Belarus, there is currently no appropriate context allowing the implementation of the actions foreseen in this programme with legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine. Therefore, even where such entities are not subject to EU restrictive measures, such legal entities are not eligible to participate in any capacity. This includes participation as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any). Exceptions may be granted on a case-by-case basis for justified reasons.
With specific regard to measures addressed to Russia, following the adoption of the Council Regulation (EU) 2024/1745 of 24 June 2024 (amending Council Regulation (EU) No 833/2014 of 31 July 2014) concerning restrictive measures in view of Russia’s actions destabilising the situation in Ukraine, legal entities established outside Russia but whose proprietary rights are directly or indirectly owned for more than 50% by a legal person, entity or body established in Russia are also not eligible to participate in any capacity. - Measures for the protection of the Union budget against breaches of the principles of the rule of law in Hungary — Following the Council Implementing Decision (EU) 2022/2506, as of 16 December 2022, no legal commitments can be entered into with Hungarian public interest trusts established under the Hungarian Act IX of 2021 or any entity they maintain. Affected entities may continue to apply to calls for proposals and can participate without receiving EU funding, as associated partners, if allowed by the call conditions. However, as long as the Council measures are not lifted, such entities are not eligible to participate in any funded role (beneficiaries, affiliated entities, subcontractors, recipients of financial support to third parties, etc.).In case of multi-beneficiary grant calls, applicants will be invited to remove or replace that entity in any funded role and/or to change its status into associated partner. Tasks and budget may be redistributed accordingly.
