NanoLAB at mmc2019 in Manchester

NanoLAB will be participating in Microscience Microscopy Congress at Manchester Central, UK. This is Europe’s leading Microscopy and Imaging conference in 2019 run by the Royal Microscopical Society (RMS), with 36 conference sessions, technique training workshops, and a free exhibition with over 90 trade companies.

As Chair of the RMS Engineering and Physical Sciences Section, Professor Beverley Inkson has overseen organisation of six Engineering and Physical Sciences sessions including Focused Ion Microscopy (FIB), Xray MicroCT, and Earth, Planetary and Archaeological Science.

Good luck to NanoLAB students Laura and Sajid who will present their work on batteries and liquid microscopy!

Research visit in Germany to study surface layers on high voltage Li-ion battery materials

Our PhD Student Laura Wheatcroft visited Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany to use their Helium Ion Microscope (HIM) and Secondary Ion Mass Spectrometry (SIMS) equipment to analyse surface layers on high voltage Li-ion battery materials.

"High voltage Li-ion battery cathodes undergo a number of degradation mechanisms during cycling. One of these mechanisms is the formation of nano-metre thick surface films from the degradation of the electrolyte at high potentials which can contain Lithium."

"HIM has very high surface sensitivity for imaging and SIMS is one of the few techniques which can detect Lithium. The combination of HIM and SIMS offers the unique opportunity to analyse the microstructure and chemically characterise the surface layers", Laura explains.

The work was performed in collaboration with Dr Nico Klingner and Dr Gregor Hlawacek from HZDR, and Johnson Matthey.
