What this call funds

Expected Outcome

Proposals are expected to contribute to all following points:

  • Significantly reduced EU dependency on imported battery-grade raw materials, specifically emerging technologies and carbon-based electrode materials.
  • Established European value chains for next-generation battery materials, enhancing the EU's technological leadership and strategic autonomy.

Scope

Proposals under this topic are expected to address all aspects for one of the following categories:

1. Sustainable Processing and Refining of next generation batteries-grade Material, delivering all of the following:

  • Development and validation of innovative, environmentally friendly refining technologies for producing battery-grade metals and materials suitable for next-generation battery chemistries. This covers raw and advanced electrode materials for the components of sodium-ion batteries or beyond generation 3[1] lithium-ion batteries
  • Development of processes achieving significant reductions in carbon and ecological footprint, emissions of pollutants, energy usage, and chemical inputs. The selected processes should not negatively impact any of the aspects above or cause significant harm.
  • Validation of economic viability, environmental sustainability, and technological robustness of the proposed refining and processing solutions.

OR:

2. Utilising Bio-based Raw Materials for Battery Electrode Materials delivering on all of the following:

  • Development of synthetic graphite and/or alternative carbonous materials for battery components derived from bio-based European feedstocks (e.g., biomass, agricultural and forestry residues, lignocellulosic materials). Inactive components such as binders may also be included.
  • Comprehensive characterization and validation of developed electrode materials in sodium-ion and lithium-ion battery cells, demonstrating comparable or superior performance to conventional graphite electrodes, specifically targeting cycle stability, energy density, and charge/discharge rates.
  • Demonstration of credible pathways for pilot-scale production pathways for bio-based electrode materials including a clear techno-economic analysis and LCA/LCC impact assessment.

The Commission initiative for Safe and Sustainable by Design[2] (SSbD) sets a framework for assessing the safety and sustainability of chemicals and materials which should be considered as a reference for project proposals.

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.

null

Activities are expected to achieve TRL 4-5 by the end of the project – see General Annex B. Activities may start at any TRL.

Eligibility & conditions+

General conditions

1. Admissibility Conditions: Proposal page limit and layout

described in Annex A and Annex E of the Horizon Europe Work Programme General Annexes.

Proposal page limits and layout: described in Part B of the Application Form available in the Submission System.

2. Eligible Countries

described in Annex B of the Work Programme General Annexes.

A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects. See the information in the Horizon Europe Programme Guide.

3. Other Eligible Conditions

If projects use satellite-based earth observation, positioning, navigation and/or related timing data and services, beneficiaries must make use of Copernicus and/or Galileo/EGNOS (other data and services may additionally be used).

described in Annex B of the Work Programme General Annexes.

4. Financial and operational capacity and exclusion

described in Annex C of the Work Programme General Annexes.

5a. Evaluation and award: Award criteria, scoring and thresholds

In order to ensure a balanced portfolio of activities covering both categories of materials, grants will be awarded not only in order of ranking but at least also to one proposal dealing with the technology that has not been covered by the proposal selected first, provided they attain all thresholds (and subject to available budget). This condition to ensure a balanced portfolio will also be considered to be met if one project addressing both aspects is funded.

are described in Annex D of the Work Programme General Annexes.

5b. Evaluation and award: Submission and evaluation processes

are described in Annex F of the Work Programme General Annexes and the Online Manual.

5c. Evaluation and award: Indicative timeline for evaluation and grant agreement

described in Annex F of the Work Programme General Annexes.

6. Legal and financial set-up of the grants

The granting authority may, up to 4 years after the end of the action, object to a transfer of ownership or to the exclusive licensing of results, as set out in the specific provision of Annex 5.

Eligible costs will take the form of a lump sum as defined in the Decision of 7 July 2021 authorising the use of lump sum contributions under the Horizon Europe Programme – the Framework Programme for Research and Innovation (2021-2027) – and in actions under the Research and Training Programme of the European Atomic Energy Community (2021-2025) [[This decision is available on the Funding and Tenders Portal, in the reference documents section for Horizon Europe, under ‘Simplified costs decisions’ or through this link: https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/guidance/ls-decision_he_en.pdf]].
