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

First-cycle defect evolution of Li1−xNi1/3Mn1/3Co1/3O2 lithium ion battery electrodes investigated by positron annihilation spectroscopy

Autor: Irmgard Buchberger, Thomas Gigl, Stefan Seidlmayer, Markus Reiner, Christoph Hugenschmidt, Hubert A. Gasteiger, Ralph Gilles

Publikováno v: Journal of Power Sources. 336:224-230

In this study the structure and evolution of vacancy type defects in lithium ion batteries are investigated in respect of crystallographic properties. The relation between positron annihilation and electronic structure is discussed in terms of struct

Li-S Batteries with Li2S Cathodes and Si/C Anodes

Autor: Xueyin Cui, Irmgard Buchberger, Hubert A. Gasteiger, Himendra Jha, Stefano Meini

Publikováno v: Journal of The Electrochemical Society. 162:A1829-A1835

Lithium-sulfur (Li-S) batteries promise improved capacities over lithium ion batteries. While currently mostly metallic lithium anodes are used, the use of silicon-anodes might offer better safety and durability. However, in a lithium-sulfur-Silicon

Lithium plating in lithium-ion batteries at sub-ambient temperatures investigated by in situ neutron diffraction

Autor: Irmgard Buchberger, Johannes Hattendorff, Christian von Lüders, Michael Hofmann, Veronika Zinth, Andreas Jossen, Simon V. Erhard, Joana Rebelo-Kornmeier, Ralph Gilles

Publikováno v: Journal of Power Sources. 271:152-159

Lithium plating in commercial LiNi1/3Mn1/3Co1/3O2/graphite cells at sub-ambient temperatures is studied by neutron diffraction at Stress-Spec, MLZ. Li plating uses part of the active lithium in the cell and competes with the intercalation of lithium
