A fluoropolymer bifunctional solid membrane interface for improving the discharge duration in aqueous Al-air batteries

Andreas Züttel, Liping Zhong, Thi Ha My Pham, Manhui Wei, Meixia Zhang

Herein, a fluoropolymer bifunctional solid membrane interface (SMI) for an aqueous Al-air battery is proposed, which inhibits anodic self-corrosion, while concurrently reducing the accumulation of undesirable by-products. A battery using the SMI exhibits a ...

Electrolyte engineering via ether solvent fluorination for developing stable non-aqueous lithium metal batteries

Mounir Driss Mensi

Fluorination of solvents, useful for non-aqueous lithium-based batteries, improves the electrochemical stability but decreases the ionic conductivity. Here, the authors report a targeted functionalization of an ether solvent to balance the electrolyte ioni ...

A colloidal aqueous electrolyte modulated by oleic acid for durable zinc metal anode

Kangning Zhao

Continuous dendrites growth, as well as corrosion and side reactions of Zn metal anode seriously hinder the development of aqueous zinc ion batteries. To address these issues, oleic acid (OA) is dispersed into a 2 M ZnSO4 solution to form a novel colloidal ...

Primary Voltage Control in Active Distribution Networks via Broadcast Signals: The Case of Distributed Storage

Mario Paolone, Jean-Yves Le Boudec, Dan-Cristian Tomozei, Konstantina Christakou, Maryam Bahramipanah

In this paper, we consider an active distribution network (ADN) that performs primary voltage control using real-time demand response via a broadcast low-rate communication signal. The ADN also owns distributed electrical energy storage. We show that it is ...

Synthesis and Characterization of High-Photoactivity Electrodeposited Cu2O solar absorber by photoelectrochemistry and ultrafast spectroscopy

Michael Graetzel, Jacques-Edouard Moser, Jan Cornelius Brauer, Adriana Paracchino

We present a systematic study on the effects of electrodeposition parameters on the photoelectrochemical properties of Cu2O. The influence of deposition variables (temperature, pH, and deposition current density) on conductivity has been widely explored in ...

Differential capacitance of liquid/liquid interfaces of finite thicknesses: a finite element study

Hubert Girault, Dmitry Momotenko

Finite element simulations were used to investigate the effect of a smooth variation of permittivity across a polarized liquid/liquid interface on the differential capacitance. The results show that a relative permittivity profile can account for the varia ...
