Description of legal entity the legal entity and its main tasks

CNRS, here represented by the Laboratory of Solid State Chemistry and Energy, pursues research related to the field of energy storage and conversion. Their studies focus on the synthesis, characterisation, and determination of structure/property relationships in rechargeable battery materials for innovative battery chemistries. Various technologies such as Li/Na-ion, solid-state and aqueous batteries are heavily studied together with a recent emphasis placed on the battery internal monitoring and auto-repairing strategies. Electrocatalysis is another major activity of our unit.
The laboratory has 5 permanent researchers and nearly 20 PhD students and postdoctoral fellows of various nationalities. It contributes to various collaborations with many French industries and plays a key role in structuring and federating the French research on batteries and supercapacitors via his director (Prof. J.-M. Tarascon) who also leads the French Network on Energy Storage and Conversion (RS2E).

Tasks and justification in INSTABAT

CNRS will contribute on the following tasks of this project:

  • WP1: : Contribution in the discussions based on our experience in developing battery materials, battery systems and characterisation, contribution in the discussions based on our experience in integrating characterisation probes (reference-electrode, gas analysis, FBG for temperature and stress probing) into electro-chemical system (pouch cells and 18650 cells).
  • WP2: Development of all the sensors covered by this project by contributing in the discussions based on their experience in integrating characterisation probes into electro-chemical system (pouch-cells and 18650 cells). Testing of the chemical stability of all the sensors developed in the project. In addition, CNRS will be directly involved in the development of the RE sensor and the hardware integration of OF/FBG, PA and RE sensors. CNRS will also define sensing and chemical stabilisation strategies as well as testing the chemical stability of the sensors. CNRS will also identify the best implantation strategy for every type of sensor, in order to integrate the sensors into the cells with minimal degradation of the electro-chemical performance of the battery cell and minimal degradation of the sensing performance of the sensor. Different sensor positioning in the cells will be tested using one sensor per cell, for all the different sensors.
  • WP3: Leading of the WP. Testing on cells implanted with OF/FBG, PA and RE sensors.
  • WP5: Contribution for hardware integration of OF/FBG, PA and RE sensors. The work will consist in. Participation in the discussions regarding signal post-processing and data logging.
  • WP7: Participation in dissemination and communication activities.
  • WP8: Participation in management activities.

CV of the persons

Dr. Jean-Marie Tarascon

CNRS, 75016 Paris, France


Dr. Jean-Marie Tarascon is presently professor at the Collège-de-France holding the chair “Chimie du Solide- Energie" (CSE), but most of his early career was done in the USA, first at Cornell University (1980), then at Bell Laboratories and finally at Bellcore until 1995. Back to France he created in 2003 the European ALISTORE-ERI. Presently, as head of both the CSE and the French network on energy storage (RS2E), his research address various fundamental-technical bottlenecks pertaining to various battery technologies. He is author of about 100 patents and more than 650 publications (h=148).

Dr. Gwenaelle Rousse

CNRS, 75016 Paris, France


Dr. Gwenaelle Rousse is an expert in analytical techniques for spotting structural and morphological evolution. She will implement her expertise on the characterisation of the systems developed in this project. She has published more than 164 papers.

Dr. Sathiya Mariyappan

CNRS, 75016 Paris, France


Dr. Sathiya Mariyappan is an expert in developing and characterising new battery materials and systems. She has actively contributed for advancing new battery technologies such as Na-ion and Li-ion based on Anionic Redox processes. She will contribute to this project by applying her expertise in characterising physico-chemical processes in Li-ion batteries.

Dr. Daniel Alves Dalla Corte

CNRS, 75016 Paris, France


Dr. Daniel Alves Dalla Corte has a background in electro-chemistry applied for energy storage systems, working on various battery chemistries. His expertise involves the characterisation of materials and battery systems, including the development of operando characterisation techniques. He has also experience in technology upscaling processes for battery systems and characterisation instruments. His role within the project will be dealing with the development of sensor and sensor integration into battery cells.

Dr. Charlotte Gervillié

CNRS, 75016 Paris, France


Dr. Charlotte Gervillié obtained her PhD from PSL Research University on new fluorinated anode material for lithium ion batteries in 2020. She is now working in Collège de France on non-invasive battery sensing and monitoring. Her role within the project will be to deal with the sensor integration into battery cells and to understand of the correlation between the measured parameters and physico-chemical phenomena occurring in the battery.
