Graphite, as the most common anode for commercial Li-ion batteries, has been reported to have a very low capacity when used as a Na-ion battery anode. It is well known that electrochemical ...

Overview. The PHI 5800 X-ray photoelectron spectrometer (XPS) is equipped with a dual source anode (Al and Mg), a hemispherical analyzer for XPS and Auger electron spectroscopy (AES) analysis, ...

XPS imaging is used to determine the lateral distribution of either chemistry or elements at the surface. Rapid and high-spatial-resolution parallel images are acquired by the AXIS Supra + instrument.

This article discusses how to determine the surface area of battery anode and ... Optimizing the efficiency of the batteries requires accurate characterization of the materials used ... be measured.

The catch is that the anode also absorbs a large number of lithium ions during charging. Graphite handles them well, but a silicon anode swells more than 300%, causing its surface to crack and ...

The HR-XPS in our lab is equipped with a twin anode (Al K α at 1486.6 or Ag L α at 2984.3 eV) FOCUS 500 monochromator and a SPECS hemispherical analyzer from the PHOIBOS series. The Al monochromator ...

The XPS lab is part of the Surface Analysis Core, one of the ten research cores integrated within the MRL Facilities. At MRL, ...

Northern Graphite (TSXV: NGC) and Rain Carbon are teaming up to develop and commercialize an advanced battery anode material (BAM) used in lithium-ion batteries. The goal is to extend cycle life ...
