Joint research unit on silicon-based solutions driving Galician technological and sustainable leadership.
The general objective of UMI VOLTA is the research and development of technologically advanced electrochemical solutions, with high energy efficiency and environmentally sustainable based on silicon, with the study of sustainable compounds mainly based on biochars from high-impact species/waste in Galicia and recovery strategies for other residual materials of high interest in electrochemistry. Additionally, it will focus on the development of digitalization strategies and new applications that allow, through support for modernization and digitalization, to promote the Galician industrial model and advance not only towards highly innovative scientific-technological solutions, but also towards sustainability and decarbonisation.
To achieve this goal, VOLTA includes the following 5 lines of research:
• Micro and nano silicon synthesis technologies.
• Synthesis of biochars from natural/residual sources and CRMs from secondary sources: traceability.
• Obtaining anode materials.
• Coin-type electrochemical cell component configuration.
• Scaling of the developed materials and their evaluation in pouch cells.
TOTAL PROJECT BUDGET: €2,058,878.57
2022 ANNUITY ADVANCES:
During the year 2022, the first tasks of the UMI VOLTA have been started, which has allowed to begin to establish the main sources of biochar, their production processes, as well as the main strategies for obtaining micro and nano silicon. In addition, CRM recovery strategies, 4.0 traceability strategies and possible new uses and applications of biochar and micro/nano silicon have been successfully addressed.
2023 ANNUITY ADVANCES:
During the year 2023, the work carried out has enabled progress to be made in all aspects relating to strategies for obtaining micro and nanosilicon, carbonaceous raw materials, CRM recovery, new uses and all of this accompanied by 4.0 traceability strategies. The optimisation and development of electrochemical cells for testing the materials under study has begun, making it possible to evaluate their suitability for the development of high-performance lithium-ion cells.
The actions carried out by the Unidad Mixta de Investigación “VOLTA” are subsidized by the Galician Innovation Agency (Xunta de Galicia) within the framework of the 2022 call for the Unidad Mixta de Investigación Program, co-financed by the European Union through the European Regional Development Fund (FEDER) – Galicia Operational Programme FEDER 2021-2027.
