Composition analysis of LIB cathode material active substances by ICP luminescence analysis.

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

We would like to 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 analyze which elements are contained in liquid samples 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 samples, as well as quantitative analysis of substances regulated by RoHS directives. *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 the particles, and the angular dependence of the intensity of the light scattered by the particles is measured. By measuring the angular dependence of the scattered light intensity, the particle size distribution (particle size distribution) is calculated from the data. Using commercially available reagents as samples, measurements were conducted in a dry state without dispersing in a solvent. The particle size measurement results for NMC oxides showed a monodisperse state with particle sizes below several tens of micrometers, and the median diameter was calculated to be 12 micrometers. [Case Overview] ■ Measurement Method ・Dry method ■ Particle Size Measurement Results for NMC Oxides ・Monodisperse state with particle sizes below several tens of micrometers ・Median diameter is 12 micrometers *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 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.

We have introduced our commercial aroma diffuser "Majesta Fragrance" at a karaoke bar located in the city. The model we installed is [MF-02S]. From the moment customers open the door, a gentle fragrance spreads throughout the store, enhancing the atmosphere. We hope to create a memorable store that customers will want to visit again through the use of fragrance. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in our fragrance services, please feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
