CIDETEC Energy Storage: bridging advanced materials and industrial energy storage devices

CIDETEC Energy Storage is an applied research centre specialising in advanced energy storage technologies. We develop battery technologies from the materials level through to the manufacturing and validation of cells at pre-industrial scale, covering the entire value chain. Our mission is to accelerate technology transfer to industry and support a sustainable energy transition in Europe.

Within the ARMS project, CIDETEC Energy Storage contributes its expertise as the partner responsible for translating technologies developed in the initial work packages into functional devices. Our team specialises in electrode processing and pilot-scale cell assembly, bringing extensive experience in adapting emerging technologies to industrial manufacturing processes.

As part of ARMS, CIDETEC plays a key role in WP2 (Electrode Fabrication). In this work package, based on the active materials developed earlier in the project, our team optimises electrode formulations and processing steps, including mixing, roll-to-roll coating, drying, and calendering. The objective is to produce stable, high-quality electrodes that are fully compatible with cell assembly.

In parallel, within WP5 (Supercapacitor Device Integration and Demonstration), CIDETEC is responsible for assembling asymmetric cells using multi-layer stacking processes and Z-folded separators. This includes critical steps such as electrolyte filling, conditioning, and cell sealing. Following successful validation of the electrochemical performance of the new materials—aimed at increasing energy density without compromising power capability or cycle life—these cells will be deployed as replacements in wireless environmental monitoring applications.
