WELCOME

The production of improved battery systems is an essential step in reducing world-wide dependence on fossil fuels, as it is necessary for the development of hybrid and electric vehicles. In addition, the extended use of renewable energies can only be successful if these technologies are integrated into a smart-grid style distribution network of high performance storage systems, that are both safe and inexpensive to produce. In this context, our research focuses on ionic and/or electronic conductive materials with an application in the field of energy storage/ conversion.

The development of the next generation of batteries requires foreseeing the requirements of a global energy distribution system. As shown in the diagram below, our research activities primarily focus on 4 aspects:

SYNTHESIS

The synthesis and characterization of inorganic materials (electrodes and solid electrolytes). These materials are synthesized such that they have electrical properties that make them suitable for their future use.

SHAPING

Ceramic and polymer materials are shaped for their roles in all solid-state and polymer batteries. This requires mastering the processes used for material shaping and formulation control for composite electrodes to guarantee optimum battery performance.

ASSEMBLY

Electrochemical devices (based on ceramics and/or polymers) are assembled from composite electrodes and electrolytes. Battery performance is obtained and is studied based on cell operating conditions (temperature, current, potential applied, etc.).

diagnosis

Issues with our batteries can be diagnosed based on the electrochemical behavior of these devices in order to better understand the limitations of our systems. We are particularly interested in the electrode/ electrolyte interface reactions that are responsible for battery aging as well as the production of safer batteries
