Top-Class Volume-Specific Capacity: High-Capacity Anode Materials for Secondary Batteries

When using tin sulfide as the negative electrode material for lithium-ion batteries, the theoretical capacity of tin sulfide is 4.7 times that of graphite by volume and 2.1 times that of graphite by mass. In terms of actual discharge capacity by volume, our tin sulfide is a high-capacity negative electrode material on par with silicon-based negative electrode materials. It has also been reported to excel in fast charge and discharge performance. Additionally, since the elements that make up tin sulfide are sulfur and tin, which are abundant in nature, cost reduction during mass production is expected. This tin sulfide powder is a uniform mixture created by adding acetylene black, a conductive additive, to our developed tin sulfide dispersion with excellent dispersibility. Furthermore, changes in particle size, type of additives, and amount of additives can also be considered for this tin sulfide powder. Please feel free to contact us!

《トップクラスの体積当たり容量》 二次電池負極向け高容量負極材料

当社は本硫化スズの微細化プロセスを新たに開発することにより、高い分散性を持った硫化スズ粒子の開発に成功しました。水を溶媒として用いた5wt%硫化スズ分散液を例にあげると、流体力学的直径は256.8nmのナノ粒子を有し、透過率は0.04%、ゼータ電位－44mVと高い分散性を示しています。17時間の沈殿テストにおいても、流体力学的直径1086.6nmを有する5wt%硫化スズ分散液の比較例が17時間後沈殿しているのに対し、本5wt%硫化スズ分散液は17時間後も分散状態を維持することが実証されました。 主な使用用途としては二次電池の負極材を想定しています。硫化スズをLIBの負極に使用した場合、硫化スズの理論容量は体積あたりで黒鉛の4.7倍、質量あたりで黒鉛の2.1倍となります。体積あたりの実放電容量においては、当社の硫化スズはシリコン系負極材に並ぶ高容量負極材です。かつ、高速充放電性能に優れていることも報告されています。また、硫化スズを構成する元素は硫黄と錫であることから自然界に豊富に存在し、量産時のコストダウンが期待されます。お気軽にお問合せ下さい！

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

In civil engineering sites, there are many instances where temporary roads, access routes, heavy machinery workspaces, and material storage areas use ground plates. Traditional steel plates are heavy, requiring large machinery for installation and removal, which can make work difficult in narrow sites. Hyper CLT ground plates are lightweight civil engineering CLT materials made from wooden CLT for civil use. A 5×10 plate weighs about 230 kg, and a 5×20 plate weighs about 460 kg, making them easy to handle even with small machinery, thus reducing the burden of transportation, installation, and removal. They are easy to use in sites with limited space or where the use of large machinery is difficult. They can be widely used for temporary roads, heavy machinery scaffolding, pathways within the site, and material storage protection, contributing to glare reduction, noise reduction, and environmental consideration. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," they are also recommended as materials for innovative ideas and safety measures in public works.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. Many implementation examples are also presented, so please take a look at the case study page.
