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 such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks 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 with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.
