Improving Cycle Life of Silicon-Dominant Anodes Based on Microscale Silicon Particles under Partial Lithiation

Autor: Stefan Haufe, Johanna Ranninger, Rebecca Bernhard, Irmgard Buchberger, Eckhard Hanelt

Publikováno v: Batteries, Vol 9, Iss 1, p 58 (2023)

Using only parts of the maximum capacity of silicon microparticles in a lithium-ion battery (LIB) anode represents a promising material concept. The high capacity, better rate capability compared with graphite and accessibility on an industrial scale

From Screening to Scale-Up: The DoE-Based Optimization of Electrochemical Reduction of l-Cystine at Metal Cathodes

Autor: Caroline Neff, Tobias Gärtner, Stefan Haufe, Siegfried R. Waldvogel, Johannes Seidler, Rebecca Bernhard

Publikováno v: Organic Process Research & Development. 25:2622-2630

Design of experiment (DoE) is a powerful statistical tool in establishing improved chemical processes. An optimization and scale-up of the electrochemical reduction of l-cystine to l-cysteine is pr...

Effect and Progress of the Amorphization Process for Microscale Silicon Particles Under Partial Lithiation As Active Material in Lithium-Ion Batteries

Autor: Maximilian Graf, Rebecca Bernhard, Clara Berg, Jürgen Pfeiffer, Stefan Haufe, Hubert A. Gasteiger

Publikováno v: ECS Meeting Abstracts. :357-357

Silicon electrodes in lithium-ion batteries undergo large volume changes during (de-)lithiation.[1] This leads to severe morphological changes over extended charge/discharge cycles, resulting in particle pulverization and surface area increase concom

Gas Evolution at Graphite Anodes Depending on Electrolyte Water Content and SEI Quality Studied by On-Line Electrochemical Mass Spectrometry

Autor: Hubert A. Gasteiger, Michael Metzger, Rebecca Bernhard

Publikováno v: Journal of The Electrochemical Society. 162:A1984-A1989

The gas evolution during the formation of graphite electrodes is quantified by On-line Electrochemical Mass Spectrometry (OEMS) for dry electrolyte (< 20 ppm H2O) and 4000 ppm H2O containing electrolyte to mimic the effect of trace water during the f

Poly(ethylenglycol)dimethylether–lithium bis(trifluoromethanesulfonyl)imide, PEG500DME–LiTFSI, as high viscosity electrolyte for lithium ion batteries

Autor: Stefania Panero, Alessandro Latini, Bruno Scrosati, Jusef Hassoun, Rebecca Bernhard

Publikováno v: Journal of Power Sources. 226:329-333

In this paper we report a poly(ethylenglycol)dimethylether–lithium bis(trifluoromethanesulfonyl) imide (PEG500DME–LiTFSI) as high viscosity, safe electrolyte for lithium ion batteries. The high molecular weight of the end-capped ether solvent is
