Case study of failure analysis of oxide-based all-solid-state batteries.

It has high safety and can be used in various environments! Consistent analysis is possible.

We present a case study of a series of analyses conducted to identify failure points and perform cross-sectional observations on an oxide-based all-solid-state battery that was destroyed during reliability testing. Thermal analysis revealed a tendency for strong heat generation on the side, and X-ray transmission observations showed white linear contrast anomalies near the boundary where heat generation was observed in the X-ray transmission image. It is suspected that some abnormalities may have occurred in the white line area. When CP cross-sectional SEM observations were conducted on the areas where anomalies were visible, layer delamination was observed. It is inferred that delamination occurred between the current collector and electrolyte layers due to the expansion and contraction of the positive (negative) electrode layers during reliability testing. 【Case Overview】 ■ Sample Information: Oxide-based all-solid-state battery that experienced degradation due to charge and discharge testing ■ Thermal Analysis Results: A tendency for strong heat generation on the side was observed ■ Other Analysis Contents: - X-ray transmission observation - CP cross-sectional observation and elemental analysis via SEM *For more details, please refer to the PDF document or feel free to contact us.

• Batteries and Capacitors

The purity of the electrolyte greatly affects the performance of the battery! It suppresses the volatility of sulfur components and converts them into a form that can be detected by IC.

We will introduce an example of analyzing the purity of diphosphorus pentasulfide using ion chromatography for the composition analysis of raw materials for all-solid-state batteries. Diphosphorus pentasulfide is one of the raw materials used in the production of electrolytes for sulfide-based all-solid-state batteries. As a pretreatment for IC measurement, the powder of diphosphorus pentasulfide was dissolved in alkaline water and converted into phosphate and sulfide salts. Subsequently, the sulfide ions were oxidized to sulfate ions to prepare the IC measurement solution.

• Analysis and prediction system

It is possible to perform non-destructive testing from fault location identification to internal observation! High-precision identification of heat generation areas can be achieved.

Thermal analysis is a method for identifying defective areas by detecting the heat generated at leak points due to applied voltage using a high-sensitivity InSb camera. By detecting the weak heat generated from shorts and leaks with a high-sensitivity InSb camera, it is possible to non-destructively identify the failure points of electronic components such as semiconductors. Furthermore, non-destructive observation can also be performed using X-ray inspection equipment. 【Features】 ■ Identifying defective areas by detecting the heat generated at leak points with a high-sensitivity InSb camera ■ Analyzing samples in a non-destructive state, and analyzing electronic components that are difficult to analyze with OBIRCH or emission methods is also possible ■ By using the lock-in function to obtain phase information, it is possible to accurately identify the heat generation points *For more details, please refer to the PDF document or feel free to contact us.

Cracks that couldn't be detected visually might be found with X-rays!

When stress such as warping, bending, or twisting is applied to the printed circuit board, cracks may occur inside the MLCC (Multi-Layer Ceramic Chip Capacitor). Moreover, cracks that develop internally are often hidden beneath the electrodes, making it difficult to detect them through visual inspection. In such cases, how about checking with X-rays? [Observation Details] ■ Oblique CT Observation It is possible to perform CT without destroying the printed circuit board, in its original state. ■ Orthogonal CT Observation It is possible to observe the shape of the components in their original state. *For more details, please refer to the PDF document or feel free to contact us.
