Despite a different objective, the RHINOCEROS project partners have shown growing interest in the Digital Battery Passport, an initiative of FREE4LIB, a sister project from the Cluster Hub “Production of raw materials for batteries from European resources”. This collaboration shows our commitment to contributing to the European battery community through the exchange of knowledge and experience.

The FREE4LIB workshop had a three-fold objective, including a brief presentation of the preliminary results of the battery passport concept development, the outline of the implementation challenges and potential follow-ups of industrial scale-up, and the clear differentiation between battery second use (B2U) versus recycling. The event drew approximately 50 participants from various segments of the battery value chain, which ensured a comprehensive and multifaceted perspective of the subject matter.

The introductive session presented the FREE4LIB project, briefly highlighting past achievements and focusing mainly on the remaining activities outlined in the workplan. The following session was led by Julius Ott (industrial engineer with expertise in circular economy at Karl-Franzens-Universität Graz). During the past year, researchers at Univ. of Graz worked on finalising data collection and processing related to the development of a data model of the digital passport platform which aims to close the information gap between beginning-of-life (BoL) and end-of-life (EoL) battery lifetime. This interactive session turned out to be an appropriate opportunity for researchers at Univ. of Graz to present the outcomes of their data collection and handling, and to evaluate their relevance within the reality portrayed by the workshop attendees.

Participants, predominantly familiarised with the EU-funded battery projects, confirmed the findings reported by Univ. of Graz. However, they also raised concerns about data sharing. The outcomes of the interactive session, complementing prior research, will serve as valuable guidance for the FREE4LIB project in implementing the battery passport within their project.
