Bae, D. (author), Faasse, Richard (author), Smith, W.A. (author)Achieving high current densities without thermal performance degradation at high temperatures is one of the main challenges for enhancing the competitiveness of photo-electrochemical energy storage systems. We describe a system that overcomes this challenge by incorporating an integrated photoelectrode with a redox flow cell, which functions...journal article 2020

(author), Wagemaker, M. (author), Eichel, Rüdiger A. (author)High-fidelity and facile ex situ transmission electron microscopy (TEM) characterization of lithium−oxygen (Li−O<sub>2</sub>) batteries is still limited by challenges in preserving the native environment of Li−O<sub>2</sub> discharge products. The extreme reactivity and moisture sensitivity of the discharge products means that they are...journal article 2020

(author)The increasing share of renewables in electric grids nowadays causes a growing daily and seasonal mismatch between electricity generation and demand. In this regard, novel energy storage systems need to be developed, to allow large-scale storage of the excess electricity during low-demand time, and its distribution during peak demand time....journal article 2020

Grazian, F. (author), Shi, W. (author), Soeiro, Thiago B. (author), Dong, J. (author), van Duijsen, P.J. (author), Bauer, P. (author)In high-power wireless battery charging that uses inductive power transfer, a considerable amount of power losses are located in the transmitter and receiver coils because they carry high resonant currents and typically have a loose coupling between them which increases eddy current losses. Therefore, the nominal operation needs to be chosen...conference paper 2020

Bae, D. (author), Kanellos, Gerasimos (author), Wedege, Kristina (author), Dražević, Emil (author), Bentien, Anders (author), Smith, W.A. (author)MoOX is commonly considered to be a high work-function semiconductor. From x-ray photoelectron spectroscopy and photoelectrochemical analysis, it is shown that MoOX can be considered as an effective hole transfer layer for the GaP-based device. Specifically, in the absence of carbon contamination using an ion beam cleaning step, the oxygen...journal article 2020
