X-ray radiographic and tomographic investigations of cycled lithium ion batteries

Sun, Fu (2017)

Lithium ion batteries (LIBs) have become the predominant power supplies in portable electronic devices such as cell phones, laptops and tablets. They are regarded as promising candidates to power f...

Particle-stabilised foams: structure and aging

Stocco, Antonio; Garcia-Moreno, Francisco; Manke, Ingo; Banhart, John; Langevin, Dominique (2011)

We show that aqueous foams stabilised by nanoparticles can be easily imaged using an X-ray laboratory source. We have used hydrophobically modified silica nanoparticles that confer to the foam a re...

Kinetics of coalescence in liquid aluminium foams

Garcia-Moreno, Francisco; Solorzano, E.; Banhart, Jon (2011)

The cell wall rupture kinetics for a collection of AlSi9 foam samples kept at a constant temperature over the melting point for a long time period (700 s) has been characterized by in situ X-ray ra...

The rupture of a single liquid aluminium alloy film

Heim, K.; Garcia-Moreno, F.; Kumar, G. S. Vinod; Rack, A.; Banhart, J. (2014)

The present study is based on the idea of understanding the rupture of films in metal foams by studying free standing metallic films as a model system. Liquid dynamics, the velocity of the rupturin...

On the structural integrity and electrochemical activity of a 0.5Li(2)MnO(3)center dot 0.5LiCoO(2) cathode material for lithium-ion batteries

Rana, Jatinkumar; Klöpsch, Richard; Li, Jie; Scherb, Tobias; Schumacher, Gerhard; Winter, Martin; Banhart, John (2014)

Structural changes in a 0.5Li2MnO3·0.5LiCoO2cathode material were investigated by X-ray absorption spectroscopy. It is observed that both Li2MnO3and LiCoO2components of the material exist as separa...
