CIDETEC is a private organization for applied research founded in 1997. Located in the city of Donostia-San Sebastián, CIDETEC is divided into three international technological reference institutes in Energy Storage, Surface Engineering and Nanomedicine. CIDETEC Energy Storage is specialized in creating new battery technologies (including lithium metal solid state batteries) according to specific challenges, and its ultimate transference to the industry. The institute has the capacity to develop complete products and processes and offers material validation, pilot manufacturing, pack engineering and battery testing services. CIDETEC Energy Storage is also a regular participant and coordinator in H2020 European funded projects (SI-DRIVE, SPIDER, IMAGE, SAFELIMOVE, E-Magic, VIDICAT and COFBAT EU etc.) dealing with different types of solid electrolytes and advanced battery technologies. Finally, CIDETEC Energy Storage is involved as well in the core team of BATTERY 2030+, the initiative for a long-term large-scale research program towards the European battery of the future. CIDETEC Energy Storage involves more than 100 specialized researchers distributed into two technological units: Materials for Energy -80 researchers with a background of chemistry, electrochemistry and materials- and Systems Engineering -25 researchers: electrical and mechanical engineers.

In SIGNE project, CIDETEC Energy Storage will be responsible of the full cell harmonisation of SIGNE cells (WP5). This activity includes the slurry formulation and processing of anode and cathode materials, the integration of glyoxal electrolytes and fibre separators to the full cell system and the cell prototyping to small pouch cell level (0.1 Ah-0.5 Ah). CIDETEC will also bring its know-how on anode development (WP1), cathode development (WP3), cell standardisation (WP6), LCA assessment (WP7) and cell testing of 51 Ah prototype cells (WP8).
