They play the role of federator in the RS2E by acting as integration vectors. They are the heart of the network as they gather all the necessary expertise to successfully bring to an end the projects initiated among the various thematics. There are 3 of them.
- Materials compatibilities: Activities mainly centered on i) setting up advanced electrochemical tests/protocols, ii) post-mortem studies of batteries and supercapacitors in order to determine the key to their dysfunction and bring solutions via the addition of additives or formation tests.
- Theory: Staying tuned to the experimentalists’ remarks, the «theory» group develops methods and strategies in order to i) act as a guide in the search for new materials, ii) understand reactivity at the interfaces in nanostructured electrodes, iii) simulate the experiment, and iv) predict the electrochemical and chemical stability of the electrodes and electrolytes.
- Instruments: This section deals with the new characterization measures (ex situ and in situ) in the vanguard of technology; amongst the various ways, there is the development of in situ methods of i) battery imaging via RMN or RX, ii) observation and characterization of the interfaces evolution (morphology and composition) via HRTEM or HREELS, etc.
