Since the beginning of the twenty-first century the limitations of the fossil age with regard to the continuing growth of energy demand, the peaking mining rate of oil, the growing impact of CO2 emissions on the environment and the dependency of the econom ...
In the domain of energy storage, electrochemical capacitors have numerous applications ranging from hybrid vehicles to consumer electronics, with very high power density at the cost of relatively low energy storage. Here, we report an approach that uses ve ...
The behavior of metals at high pressure is of great importance to the fields of shock physics, geophysics, astrophysics, and nuclear materials. We study here bulk crystalline aluminum from first principles at pressures up to 2500 GPa - soon within reach of ...
A compact energy‐storage system based on redox targeting is proposed, by which insulating LiFePO4 particles can be reversibly charged and discharged by redox shuttle molecules (S; see scheme) even in the absence of conducting additives. The energy density ...
Regarding traction systems, new solutions can be proposed today, where energy storage with supercapacitors can offer an easier energy management, together with a strong decrease of the constraints applied to the main energy source of such systems. The ener ...
Supercapacitors represent one of the newest innovations in the field of electrical energy storage, and will find their place in many applications where energy storage is needed, or can help to the smoothing of strong and short-time power solicitations of a ...
Due to their high specific energy and energy density, micro-solid oxide fuel cells1,2 (µ-SOFCs) are seen as one of the technologies that could help satisfying the continuously increasing demand for electric energy in portable electronic devices. The µ-SOFC ...
Within the Born-Oppenheimer picture of the electronic Schrödinger equation the external potential due to the nuclei influences the resulting expectation values during the self consistent field procedure. In this thesis, the optimization and the benefit of ...
Supercapacitors represent one of the newest innovations in the field of electrical energy storage, and will find their place in many applications where energy storage is needed, or can help to the smoothing of strong and short time power solicitations of a ...
Supercapacitors are electrochemical double layer capacitors, dedicated for the energ storage. Even if the energy density is still lower than that one of batteries, the supercapacitors are defined with a higher power density. The main advantage of that prop ...
