Vanadium-oxygen cell for positive electrolyte discharge in dual-circuit vanadium redox flow battery

Hubert Girault, Justyna Piwek, Alberto Battistel, Christopher Raymond Dennison

The “dual-circuit redox flow battery” takes advantage of a conventional all-vanadium redox flow battery (VRFB) combined with a separated catalytic hydrogen evolution reactor. Depending on demand, the VRFB can be conventionally discharged or supply H2 by us ...

Phase field parameters for battery compounds from first-principles calculations

In this work, we present and apply schemes to determine from first-principles calculations the relevant effective parameters used in phase field theory simulations of battery compounds. In particular, we derive that a consistent free energy density can be ...

5.2 Energy-Efficient Low-Noise CMOS Image Sensor with Capacitor Array-Assisted Charge-Injection SAR ADC for Motion-Triggered Low-Power IoT Applications

Kyojin Choo, Li Xu

As IoT is increasingly integrated into our everyday life, the demand for different sensor modalities, especially imaging, is rising. IoT imagers are often compact and have small form-factor batteries and thus must be designed with both low power (improving ...

A Receding Horizon Control Approach For Re-Dispatching Stochastic Heterogeneous Resources Accounting for Grid and Battery Losses

Jean-Yves Le Boudec, Mario Paolone, Fabrizio Sossan, Emil Namor, Eleni Stai

In this paper, we propose a re-dispatch scheme for radial distribution grids hosting stochastic Distributed Energy Resources (DERs) and controllable batteries. At each re-dispatch round, the proposed scheme computes a new dispatch plan that modifies and ex ...

Bottom slope influence on flow and bedload transfer through contractions

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt

In-stream open check dams are essential for flood protection at mountain rivers that are characterized by steep slopes (>1%) and sediment-laden flood discharges. These structures comprise an opening acting as a lateral or vertical flow contraction to force ...

Modeling, understanding, and screening fast lithium-ion conductors for solid-state electrolytes

Leonid Kahle

The Li-ion batteries within the consumer electronics used in our everyday life suffer from well-known deficiencies due to the prevalent use of organic liquid electrolytes: the narrow electrochemical stability windows of the organic solvents used in these e ...

Solid electrochemical energy storage for aqueous redox flow batteries: The case of copper hexacyanoferrate

Hubert Girault, Pekka Eero Peljo, Evgeny Smirnov, Grégoire Clément Gschwend, Christopher Raymond Dennison, Danick Reynard, Solène Cindy Gentil, Elena Zanzola

All redox flow batteries suffer from low energy storage density in comparison with conventional Li-ion batteries. However, this issue can be mitigated by utilization of solid energy storage materials to enhance the energy storage capacity. In this paper we ...
