COLLABAT Cluster

A collaborative European network for advanced battery pack technologies.

The S4MILE project is part of the COLLABAT Cluster, a collaborative network bringing together European R&I projects working on next-generation battery systems and their integration into electric mobility.

COLLABAT promotes knowledge exchange, synergies and joint visibility across complementary projects, while strengthening connections between research, industry and other key actors in the European battery ecosystem.

Main Objectives

Strengthen the exchange of knowledge and experience between projects working on advanced battery technologies.

Identify technical and strategic synergies that can reinforce the work carried out by individual projects.

Promote dialogue around battery-pack design, testing, validation, safety, performance and integration.

Increase the visibility of project results through joint dissemination and communication activities.

Encourage participation in common workshops, conferences and other relevant events.

Facilitate interaction between research, industry and other actors across the European battery value chain.

Support the wider uptake and transfer of innovative battery solutions for electric mobility.

Current Projects

S4MILE is developing new approaches for integrating next-generation solid-state batteries into electric vehicle structures.
