Introducing examples of measurement cases for important management items in the production of lithium-ion batteries and all-solid-state batteries!

We would like to introduce a case of particle size measurement of cathode active materials using laser diffraction conducted by our company. In air or liquid, laser light is irradiated onto particles, and the angular dependence of the intensity of light scattered by the particles is measured. The angular dependence of the scattered light intensity is measured, and from that data, the particle size distribution (particle size distribution) is calculated. Commercially available reagents were used as samples, and measurements were conducted in a dry state without dispersing in a solvent. The particle size measurement results for NMC oxide showed a monodisperse state with particle sizes below several tens of micrometers, and the median diameter was calculated to be 12 μm. 【Case Overview】 ■ Measurement Method ・Dry ■ Particle Size Measurement Results for NMC Oxide ・Monodisperse state with particle sizes below several tens of micrometers ・Median diameter is 12 μm *For more details, please refer to the PDF document or feel free to contact us.

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 would like to introduce an example of analyzing the purity of phosphorus pentasulfide using ion chromatography for the composition analysis of raw materials for all-solid-state batteries. Phosphorus 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 phosphorus pentasulfide was dissolved in alkaline water and converted into phosphate and sulfide salts. Subsequently, sulfide ions were oxidized to sulfate ions to prepare the IC measurement solution.

Contec has added a BTO menu for the Windows 11-based embedded OS - Windows 11 IoT Enterprise LTSC 2024 to its industrial computer "MR4310 series" and has started accepting orders.

Contec has developed the Ethernet wireless converters "RP-WAH-SR12" and "RP-WAH-SR22," which utilize 920MHz sub-gigahertz wireless (IEEE 802.11ah) to enable Ethernet communication wirelessly even at distances of up to 1 km. Sales began on August 21, 2025. The new products are compact IEEE 802.11ah compliant wireless LAN converters that can be installed in various locations. The new Wi-Fi standard "IEEE 802.11ah," which utilizes sub-gigahertz wireless communication, became available in Japan in September 2022. It operates in the 920MHz band without the need for a license and can be used outdoors. Compared to conventional 920MHz wireless communication, it enables high-speed communication and the establishment of long-distance networks, making it expected to be utilized in large factories, plants, and farms. The new Ethernet wireless converters are designed to be lightweight and compact, allowing for installation in various locations such as walls and DIN rails with the included mounting brackets. Additionally, they support external antennas, enabling the construction of flexible wireless LAN systems.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed without causing any thermal impact on the base material. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
