Reversible photo-electrochemical device for solar hydrogen and power generation
Sophia Haussener, Saurabh Yuvraj Tembhurne, Alexandre Dominique M. Cattry, Matthieu Jonin, Mahendra Patel
A reversible photo-electrochemical device operating under concentrated irradiation could offer a stand-alone solution for producing solar fuel (in photo-driven electrolysis mode) and power (in fuel cell mode). This strategy would present the advantage of h ...
2024Redox dual-flow battery for combined electricity storage and hydrogen production
The energy transition towards a carbon-neutral and sustainable economy is one of the greatest challenges of the 21st century to combat global warming and pollution. The decarbonization process is affecting every sector of the economy (electricity, transpor ...
EPFL2022Electronic synergy to boost the performance of NiCoP-NWs@FeCoP-NSs anodes for flexible lithium-ion batteries
Research and development of flexible lithium-ion batteries (LIBs) with high energy density and long cycle life for portable and wearable electronic devices has been a cutting-edge effort in recent years. In this paper, a novel flexible self-standing anode ...
ROYAL SOC CHEMISTRY2022Redefining Energy Density for an uniaxial Dielectric Elastomer Actuator
Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne
The dielectric elastomer actuator (DEA) is a technology known to potentially provide high energy density (0.3 - 0.4 J.cm(-3)). However, in the literature, few demonstrations have been done to evaluate this figure. To well understand the ability of this tec ...
IEEE2021Carbon-Decorated Na3V2(PO4)(3) as Ultralong Lifespan Cathodes for High-Energy-Density Symmetric Sodium-Ion Batteries
In this work, several carbon-decorated Na3V2(PO4)(3) materials (NVP@C-750/800/850) are successfully fabricated using a solgel approach and subsequent heat treatment. When NVP@C-800 is used as a cathode, it shows an ultralong cycle life (2000 cycles) at a h ...
AMER CHEMICAL SOC2021Inorganic and Metal-Organic Heterogeneous Catalysts for Hydrogen Energy Applications
The main focus of this thesis is the exploration of inorganic and metal-organic heterogeneous catalysts for hydrogen (H2) energy applications. In particular, we investigated metal nanoparticles (NPs) and metal-organic frameworks (MOFs) for their employment ...
EPFL2021Monocarborane cluster as a stable fluorine-free calcium battery electrolyte
High-energy-density and low-cost calcium (Ca) batteries have been proposed as 'beyond-Li-ion' electrochemical energy storage devices. However, they have seen limited progress due to challenges associated with developing electrolytes showing reductive/oxida ...

2020Perspective-Electrochemical Stability of Water-in-Salt Electrolytes
The water-in-salt approach has expanded the electrochemical stability window of aqueous electrolytes, enabling novel aqueous batteries with relatively high cell voltages and energy densities. However, the stability of these electrolytes tends to be overest ...
2020Design guidelines for Al-12%Si latent heat storage encapsulations to optimize performance and mitigate degradation
Sophia Haussener, Selmar Rudolf Binder
We provide detailed insight into the growth kinetics of intermetallic layers formed at the interface of molten Al-12%Si with cylindrical encapsulations of 316L stainless steel. This knowledge is relevant for the design and operation of high-temperature lat ...
