Electrochemical storage is currently the most widely deployed solution to address the need for energy flexibility linked to the large‑scale integration of intermittent renewable energies. Materia Nova develops innovative materials and components for batteries and electrochemical devices, covering several technological generations (GEN3 to GEN5).

Activities focus on:

  • Ion implantation of an LCO layer or a carbon-based layer to improve electrical conductivity,
  • the synthesis, optimization and characterization of anode and cathode materials,
  • the development of advanced carbon materials, doped or not, in particular those produced via the methane Plasmalysis process,
  • the design of nanostructured anodes, including grazing‑incidence deposition (GLAD) processes and approaches compatible with roll‑to‑roll deposition,
  • the formulation of slurry‑based electrodes (active material, conductive carbon, polymer binder, solvent) and the evaluation of their mechanical and electrochemical properties.

These developments are supported by an integrated approach combining experimentation, multiscale modelling and quantum simulations, enabling the optimization of dopant nature and concentration, and anticipation of the impact of doping on the electrochemical performance of materials.

As part of the development of its activities in the battery field, Materia Nova is currently in the process of acquiring a new piece of equipment dedicated to the UL 2596 (Torch & Grit) test.

This equipment will make it possible to reproduce the extreme conditions associated with thermal runaway, combining exposure to a high-intensity flame with the projection of abrasive particles.

Its commissioning, scheduled in the coming months, will complement Materia Nova’s existing fire performance evaluation capabilities and will ultimately enable the company to offer advanced testing for the screening and evaluation of flame-retardant materials for battery applications.
