The role of the battery in sustainable development, in particular in terms of energy transition, is essential for the years to come by ensuring efficient electrochemical storage of energy. One of the challenges to overcome is to extend their lifespan and also to increase their performance. One solution being considered would be to inject intelligence into the batteries via sensors for real-time diagnosis of their state of health. The aim is therefore to use an electric sensor (nanopore) to detect the parasitic chemical species that form during battery operating cycles (Coll. Jean-Marie Tarascon). Another challenge would be to be able to trap his species by making new separators. In the long term, it would be possible to be able to treat the parts of the batteries (such as the electrodes) using biosourced materials. The objective is therefore to synthesize polyrotaxane-based materials to provide, for example, mechanical reinforcements.

Another expertise of the team is the mechanical characterization of soft matter by AFM (polymers, nanoparticles,living systems, biomimetic systems). This equipment also makes it possible to dynamically visualize the topography of materials at the nanoscale and to perform force spectroscopy measurements. The team is also a specialist in single-molecule or single-particle electrical detection through nanopores and dynamics in a confined environment.
