The overview of the work performed and the main achievements across the project till the termination are described below.
In WP1, the fellow received guidance from the project manager and supervisor on project initiation and research strategies, while the lab manager ensured safety and security training. Additionally, the fellow was trained on specialized laboratory equipment, enabling adherence to lab protocols and delivery of two presentations during group meetings. A key milestone was partially achieved with the submission and EU approval of Deliverable D1.1 (Data Management Plan).
In WP2, the progress was limited, with communication primarily occurring within the host institute’s seminars. Despite the absence of external dissemination due to early-stage results, constructive exchanges with group members facilitated new strategic directions from the supervisor. Deliverable D1.2 (Career Development Plan) was successfully submitted and approved by the EU.
In WP3, initial experiments revealed that Car-based electrolytes exhibited poor conductivity, even at elevated temperatures, deeming Car unsuitable as a standalone matrix. To address this, an innovative PEO–Car interpenetrating network (IPN) was developed, maintaining PEO’s high conductivity while enhancing mechanical strength and reducing interfacial resistance. Temperature evaluations confirmed improved conductivity at higher temperatures, marking a significant advancement in bio-based electrolyte design. However, final performance tests for solid-state batteries were not completed due to early project termination.
