The Work Packages

NAIMA project applies a holistic methodology structured around 10 interrelated work packages (WP), leading to achieve the initiative’s specific objectives.

1- Requirements, specifications and assessment protocol

Led by TIAMAT, the WP1 will be driven to define the specifications and characteristics of the battery components at cell and battery module levels. This WP will establish the basis for the future development of the enhanced Na-ion cells, the configuration of the SIB prototypes for specific Energy Storage Systems (ESS) applications, as well as their full testing as isolated elements (cell approach) and as full assembled prototypes within the business scenarios.

2- Bio-based hard carbon materials for negative electrodes

Led by CEA, this work package will be a dedicated to the development and testing of negative electrode solutions based on hard carbons. The objective of this WP is to develop and scale-up high performances carbon-based anode materials for Na-ion batteries.

3- Polyanionic and lamellar oxide materials for positive electrodes

With CNRS as a leader, the WP3 will be focused on the development and testing of positive electrode solutions based on lamellar oxides for low-cost applications and polyanionic materials for fast charge and high-power applications.

4- Novel electrolytes, prototyping & isolated battery testing

Coordinated by TIAMAT, this work package will aim to assemble the component prototypes developed in previous WPs, at battery module prototypes. WP4 will develop two designs of high performance prototypes by optimizing the electrolyte composition and formation cycle. It will also optimize the positive and negative electrode formulation, design high energy and high-power prototypes and validate safety.

5- Business scenarios

IEIT is the leader of this work package designed to demonstrate the feasibility of the sodium-ion batteries in real conditions trough three different business scenarios. To that end, a concept validation at battery pack level will be implemented; feasibility analysis of the prototypes will be defined and preliminary market acceptance and technology development roadmaps to orient the future R&I tasks towards the upscaling of the prototypes will be designed.

6- Circular economy & industry scalability

Also led by TIAMAT, this WP will be dedicated to the integration of circularity and sustainability goals into the design process of the battery such as demonstrate the target recycling efficiency and the approaches associated to re-use and recycle the spent Na-ion batteries (re-assembly, stackability, easy-recycling processes). It will also make the evaluation of the economics and the environmental savings during the life cycle of batteries.

7- Battery management system intelligence and testing

VITO will lead this WP devoted to the battery management system aiming to reduce battery’s oversizing costs, weight and shape factor as well as the charging time. Moreover, it will aim to extend battery life, increase reliability and improve safety and security. The goal of this WP is to ensure that the developed sodium ion cells can be integrated and optimally used in the ESS application.

8- Dissemination, Communication & Exploitation

Led by ZABALA, this WP will develop and implement the dissemination, communication and exploitation strategies, considering the research progress and the evolution of the business plan during the lifetime of the NAIMA project. The package will ensure the dissemination and take up of the project results by end-users and the establishment of the main pillars for a future market uptake plan.

9- Project Management

With TIAMAT as leader, the main objective of this WP will be the administrative-financial management of the project to adequately manage, coordinate and monitor the activities and ensure that the project outcomes will be in-line with the expected results. It will also certify the compliance with the legal, contractual, financial and reporting requirements of H2020 and the EC and to adequately manage the funds of the partners.

10- Ethics

Coordinated by TIAMAT, this WP will ensure that all the actors of the project follow the European ethics requirements and ensure the appropriate procedures confirming to relevant legislations which are applied and satisfied in this project.
