Electrochemical energy storage facilities and expertise

Access Description
Access to electrochemical energy storage facilities and expertise, including test structures and characterization infrastructure at CEA
Technical Offering
  • Materials characterisation using x-ray diffraction, Raman spectroscopy to establish the likely outputs of the materials
  • Raman characterisation methodology for thin layers and electrodes
  • Electrochemical test system to analyse battery characteristics of individual electrodes or electrolytes for integration in hybrid energy harvesting and storage solutions
  • Assessment of the ageing characteristics of components under various environments
  • Evolution of physico-chemical characteristics with State of Charge of the component
Main Equipment
  • Expertise in electrochemistry and lithium chemistry
  • BioLogic VSP Potentiostat galvanostat multichannel electrochemical test system:
    • Allows simultaneous test of independent cells controlled with a single PC enabling electrochemical analysis of more than one cell in parallel
    • Impedance spectroscopy of the energy storage materials can also be assessed with this system
    • Lithium based and oxygen or water sensitive materials can be housed for analysis in the argon environment
  • Cascade Prober that can allow parallel measurement of several batteries on a same 200 mm wafer
  • Ionic conductivity and Energy activation measurement
  • Ultra precise electronic conductivity measurement (down to 10-14 S/cm)
  • Climatic chamber (humidity, temperature)
Typical applications
Commercialisation of electrical energy storage solutions to enable energy harvesters as an energy sources for IoT sensors, for example to overcome the intermittent nature of the harvesting source such as solar or vibrational energy.
Case Study
An SME or research team are developing new materials for a smart battery but they need access to characterisation equipment to optimise this. EnABLES will provide access to the facilities required. A typical project will offer 10 days access to the CEA-Leti researchers and equipment required.
