Semiconductor technology reduces power battery fire risk
When a lithium-ion battery is charged, lithium ions are transported to the negative electrode and deposited on the surface of the battery in the form of lithium metal, thereby forming dendritic protrusions. These lithium dendrites can cause uncontrollable volume fluctuations and lead to reactions between solid electrodes and liquid electrolytes, which can cause fires and severely affect battery performance. To effectively solve this problem, a research team led by Dr. Joong Kee Lee of the Energy Storage Research Center of the Korea Institute of Science and Technology (KIST) successfully suppressed dendrite growth by forming a protective semiconductor passivation layer on the surface of the lithium electrode. The crystals have multiple branches and can cause fires in batteries in electric vehicles. It is understood that in order to prevent dendrite formation, the research team exposed the plasma to fullerene (C60). Fullerene is a highly electronically conductive semiconductor material that enables the formation of a semiconducting passivating carbonaceous layer between the lithium electrode and the electrolyte. The semiconducting passivation carbonaceous layer allows lithium ions to pass through, while blocking electrons through the resulting Schottky barrier, and preventing electrons and ions from interacting on and inside the electrode surface, avoiding the formation of lithium crystals and dendrite growth. Dr. Joong Kee Lee said:“The dendrite growth on the lithium electrode is effectively inhibited, which helps to improve the safety of the battery. The research proposes techniques for developing highly safe lithium metal electrodes, providing a blueprint for developing next-generation batteries without fire risks.”The next goal of the research team is to improve the commercial viability of the technology:“Replacing fullerenes with cheaper materials to make semiconducting passivating carbonaceous layers makes them more cost-effective.”
Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
