[MST Homepage] Analysis Case "Heating Degradation Test of Lithium-Ion Secondary Batteries" Published

This is a method for structural analysis of the sample surface. Due to its sensitivity to the surface compared to other analytical devices, it is suitable for identifying organic contaminants on the very surface.

This is a method for structural analysis of sample surfaces. It is suitable for identifying organic contamination on the very surface due to its sensitivity compared to other analytical devices. Using a sputter ion source, it is possible to analyze the distribution of inorganic and organic materials in the depth direction. - Structural analysis and identification of organic and inorganic compounds are possible. - Coordination data from foreign substance inspection devices can be linked. - Qualitative analysis is possible from micron-order microforeign substances to several centimeters. - It is possible to analyze the very surface with high sensitivity. - Image analysis is possible. - Qualitative analysis of depth direction analysis is possible.

Elemental analysis, state evaluation, particle size analysis, and acquisition of three-dimensional structural images at the nanoscale.

TEM (Transmission Electron Microscopy) is a method that involves irradiating a thin sample with an electron beam, imaging the electrons that have passed through or scattered from the sample, and observing it at high magnification. ■ Advantages - Enlarged images can be obtained with sub-nanometer spatial resolution, allowing for the observation and analysis of the sample's fine structure and lattice defects. - It is possible to evaluate the crystallinity of the sample and identify materials. - By fabricating samples using FIB (Focused Ion Beam), it is possible to observe specific locations within a device with pinpoint accuracy. - By combining optional features, it is also possible to analyze the composition and state of localized areas. ■ Disadvantages - It is necessary to thin the sample (in some cases, thinning may be difficult for certain samples). - It does not observe individual atoms but rather displays average information in the thickness direction of the sample (typically about 0.1 μm thick). - Sample processing and observation may lead to alteration or deformation of the sample.
