Incarceration of Iodine in a Pyrene-Based Metal-Organic Framework

Andreas Züttel, Kyriakos Stylianou, Mariana Spodaryk, Andrzej Gladysiak, Ngoc Tú Nguyên

A pyrene-based metal-organic framework (MOF) SION-8 captured iodine (I-2) vapor with a capacity of 460 and 250 mg g(MOF)(-1) at room temperature and 75 degrees C, respectively. Single-crystal X-ray diffraction analysis and van-der-Waals-corrected density f ...

Hydrogen storage and electrochemical properties of LaNi5-xCux hydride-forming alloys

Natalia Gasilova, Andreas Züttel, Mariana Spodaryk

LaNi5-type alloys are commercial materials for the negative electrode in Ni-MH rechargeable batteries. Partial substitution of La by mischmetal (Mm) and of Ni by elements like Co, Al, and Mn significantly improve the cycle stability and high-rate discharge ...

Characteristics and properties of nano-LiCoO2 synthesized by pre-organized single source precursors: Li-ion diffusivity, electrochemistry and biological assessment

Nam Hee Kwon, Andreas Züttel, Mariana Spodaryk

Background: LiCoO2 is one of the most used cathode materials in Li-ion batteries. Its conventional synthesis requires high temperature (>800 degrees C) and long heating time (>24 h) to obtain the micronscale rhombohedral layered high-temperature phase of L ...

Description of the capacity degradation mechanism in LaNi5-based alloy electrodes

Marco Roman Holzer, Andreas Züttel, Philippe Mauron, Mariana Spodaryk

The mechanism of the capacity degradation of LaNi5-based alloy electrodes was investigated with a special focus on the influence of the alloy and surface composition, as well as the unique structure obtained by gas atomisation. The electrochemical properti ...
