Among the selected projects, CIC energiGUNE will participate as a leading partner in two strategic subprojects: POLAR CLIMATE and ARISE (3D-ASSET), aimed at addressing key challenges in energy sustainability, circular economy, and advanced storage technologies.
POLAR PROJECT (SUBPROJECT UNDER THE CLIMATE FRAMEWORK): SUSTAINABLE BATTERIES FOR THE CIRCULAR ECONOMY
The POLAR project focuses on the reuse of electric vehicle (EV) batteries for second-life applications—such as in stationary storage systems—extending their lifespan through advanced diagnostic techniques. The main goal is to develop a new methodology based on electrochemical characterization to accurately measure the state of health (SOH) and remaining useful life (RUL) of lithium-ion cells.
Through a combination of non-destructive electrochemical testing and thermal modeling, POLAR will deliver predictive tools to support decision-making regarding battery refurbishment, reuse, or recycling. This will directly contribute to the energy transition and to reducing the environmental impact of the electric mobility sector.
Scientific-technical impact:
The knowledge generated will enable the development of generalized diagnostic tools for assessing battery health and performance, facilitating the potential reuse of used batteries. This represents significant value for both the scientific community and the industry, especially in second-life applications where efficient diagnostic tools can significantly extend battery lifespan.
ARISE PROJECT (SUBPROJECT UNDER THE 3D-ASSET FRAMEWORK): SUSTAINABLE COBALT-FREE SOLID-STATE BATTERIES
As part of the European 3D-ASSET project, the ARISE subproject aims to develop a new generation of solid-state batteries (ASSBs), processed using 3D printing and optimized for Internet of Things (IoT) applications.
ARISE will focus on the design of advanced 2D and 3D anodes, as well as the processing of electrolytes such as LLZO and protective LiPON coatings. Two generations of cells are envisioned, including the development of an anode-less architecture that is more sustainable and offers higher energy density. The proposed solutions will address current challenges at the solid/solid interface, enabling progress toward safer, more efficient, and environmentally friendly batteries.
International and strategic impact:
The project aligns with European priorities set out in the Battery 2030+ roadmap, the SET Plan, and the Green Deal, positioning Spain as a key player in the innovation of advanced ceramic batteries and in the reduction of critical materials like metallic lithium.
A STEP FORWARD TOWARD CLEANER AND MORE EFFICIENT ENERGY
Both projects represent a significant advance in the development of next-generation energy technologies, with expected impacts in scientific, industrial, and environmental fields. CIC energiGUNE thereby strengthens its leadership in applied research in energy storage, working closely with key stakeholders in the European ecosystem.
