Composition analysis of LIB cathode active materials by ICP luminescence analysis.

ICP emission analysis enables qualitative and quantitative analysis of approximately 70 elements, primarily metal elements!

We will introduce the composition analysis of active materials in LIB cathode materials using ICP emission analysis. The cathode material of lithium-ion batteries (LIB) is one of the important components that influence the battery's voltage and energy density, and the composition of the cathode material significantly affects the battery's performance. ICP emission analysis can determine which elements are present in a liquid sample and in what quantities. 【Features】 - Qualitative and quantitative analysis of approximately 70 types of elements is possible. - Applicable to various analyses, including qualitative and quantitative analysis of additives and impurities contained in the sample, as well as quantitative analysis of substances under the RoHS directive. *For more details, please download the PDF or feel free to contact us.

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.

At construction sites, temporary parking lots may be established for workers and construction-related vehicles. On unpaved ground, mud and ruts can easily occur due to rain, which may hinder vehicle access. Hyper CLT mats are civil engineering materials that utilize wood CLT. By laying them in temporary parking lots, a suitable environment for vehicle passage and parking can be created while protecting the ground. They can be laid only in the necessary areas, and after the construction is completed, they can be removed and repurposed for temporary roads or access routes. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to install and remove even with small machinery, allowing for changes in parking space. Additionally, they offer benefits unique to wood, such as glare reduction, noise reduction, and CO2 fixation. They are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for the development of temporary parking lots and innovative public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. 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 or download the catalog.
