Energy storage is a major strategic issue on a global scale. Reducing the production of greenhouse gases, for example, requires the use of renewable energies. Due to the intermittency of some of these energies (wind, solar, especially photovoltaic), storage is the only means of creating a time lag between production and use.

Among the existing means of storage, the most widely used - for all applications - is undoubtedly electrochemical storage using batteries.

Materia Nova proposes:

  • The development of battery components and elements, super-capacitors of different generations (GEN3, GEN4 and GEN5) as well as their characterisation at the scale of the monolayer to the half-cell
  • The selection of battery materials, deposition protocols and device architecture, as well as the fabrication of battery interface reference devices and the determination of the conductivity of thin films with impedance spectroscopy. This involves the monitoring of materials and interface properties of graphene-on-SiC Hall effect sensors and vertical rectifiers, as well as solid state thin film batteries.

Our strengths

  • Deposition of thin films and innovative battery components (electrodes, current collectors, solid electrolytes, catalysts, etc.).
  • Design and engineering of process by plasma, thermal sublimation and wet process with glove box, by ALD.
  • Material characterization platform, in monolayer or half-cell scale (morphology, electrical properties of layers and interfaces by AFM under controlled atmosphere), impedance spectroscopy for understanding interactions and degradation.
