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. For more details, please refer to the published catalog. 【Solid Electrolytes (Partial)】 ■Li3PS4 ■Li7P3S11 ■Li6PS5Cl ■Li6PS5Br *For more information, please refer to the PDF document or feel free to contact us.

• 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.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

Based on practical experience in support companies and business companies, SBS Marketing Co., Ltd. provides consulting services related to marketing, sales promotion, and customer acquisition primarily in the BtoB (business-to-business) sector. On June 4, 2026, we published a page titled "Do We Set 'Forecasts' Too Optimistically Compared to Reality? The 'Planning Fallacy'." The 'Planning Fallacy' refers to the psychological phenomenon of underestimating the time, costs, and risks involved in carrying out tasks while overestimating the benefits. The page explains examples of its occurrence, the factors that lead to it, and methods to overcome it. (Page Overview: Excerpts) ■ What is the 'Planning Fallacy'? ■ Examples of the 'Planning Fallacy' ■ Why does the 'Planning Fallacy' occur? ■ How to overcome the 'Planning Fallacy'?

Kort Valuta has released a workplace initiative model that leverages points exchangeable for electronic money to support the adoption of safety and wellness habits. Examples include: ・Hydration reporting ・Viewing heatstroke prevention content ・Pre-shift condition checks ・Voice-based condition checks By linking these activities to incentive points, organizations can encourage voluntary participation while supporting workplace safety and employee well-being. The model is designed not only for frontline environments such as: ・Logistics ・Construction ・Manufacturing but also for office-based health and well-being programs. Safety posters and reminders alone are often not enough to drive lasting behavioral change. We hope this initiative provides a practical example for organizations seeking new approaches to workplace safety and employee engagement.
