CLEARPOWER Coatings for the storage of energy from renewable sources.

This project focuses on the development of transparent or semi-transparent coatings that integrate electrical energy storage capacities and can be applied to building materials such as glass, in order to develop “intelligent windows”. Ultimately, the aim is to be able to integrate this technology into office buildings and private homes in order to meet certain future societal needs aimed at energy autonomy with a reduced environmental impact. The technology is intended to be complementary to intermittent energy production solutions such as photovoltaic panels or wind turbines that do not allow a controlled energy production. It is also intended to complement other energy storage solutions currently under development such as pumped storage.


Objectives and missions of Materia Nova

The main objective is the inclusion on glass of transparent Li-ion batteries with a transparency of more than 80% and a cycling resistance of more than 1000 cycles (charge and discharge). The project aims more particularly to develop large prototype elements (1:1 scale windows) in order to demonstrate the technical feasibility of this solution. Within the consortium, Materia Nova will be more particularly involved in:

  1. The selection of materials for the anode and cathode and validation under the appropriate experimental conditions.
  2. The additive manufacturing processes of electrodes and current collectors for (semi-)transparent Li-ion batteries.
  3. The manufacturing processes for multi-layer systems by controlled laser ablation for (semi-)transparent Li-ion batteries.
  4. Prototyping and eco-design of (semi-)transparent Li-ion batteries.
