Aggregates, Interfaces and Materials for Energy (AIME)
Institut Charles Gerhardt, Université Montpellier 2, France


-
The team "Aggregates, Interfaces and Materials for Energy" (AIME) associates competence in innovative synthesis routes to hierarchical materials with tailored architecture and in surface reactivity and the chemistry of interfaces, with complementary theoretical and experimental approaches applied to energy storage and conversion and environmental remediation processes.
The perspectives of the research are two-fold: elaboration of original materials enabling emerging energy technologies and the study of the interfacial properties and mechanisms governing exchange of energy and matter at interfaces

RESEARCH ACTIVITIES
Our research activities within ALISTORE consists in the optimisation of Li-ion battery systems and the development of alternative innovative energy storage systems with high energy and power densities. Our know-how is centered on synthesis, electrode formulation and electrochemical characterisation. State-of-the-art in situ and operando techniques (XRD, Mössbauer spectroscopy…) are continuously developed and employed to get deeper insight into the electrochemical mechanisms and their failure.
