In recent years, solid-state batteries have been attracting attention as a next-generation energy storage technology. This technology is expected to replace lithium-ion batteries, and is characterized by its high safety and long life. There are two main types of solid-state batteries, oxide-based and sulfide-based, depending on the material used as the solid electrolyte.
Oxide-based solid-state batteries use oxides as solid electrolytes and are considered to have particularly high chemical safety. Therefore, they are suitable for use in high-temperature environments and are considered to have excellent safety. However, because their ionic conductivity is relatively low, further technological development is needed to improve the performance of the batteries.
In contrast, sulfide-based all-solid-state batteries use sulfide as a solid electrolyte and are characterized by their high ionic conductivity. This is expected to improve battery performance, and they are attracting particular attention for their application to electric vehicles and energy storage systems. However, sulfide-based all-solid-state batteries have one issue. When sulfide is exposed to moisture, it becomes hydrogen sulfide (H2S) may occur. Hydrogen sulfide is a toxic gas with a rotten egg odor and must be handled with care. To address these risks of hydrogen sulfide, gas detection technology is becoming increasingly important as a safety measure in safety applications and research. Our gas sensors are capable of detecting a variety of toxic gases, including hydrogen sulfide, and are characterized by their high sensitivity and reliability. These sensors play an important role in ensuring safety in the manufacturing of solid-state batteries and in experimental environments. Our gas sensors are widely used as tools to ensure safety in industrial sites and research facilities. As a result of many years of research and development, we have achieved highly accurate gas detection technology, which allows us to appropriately address issues regarding the safety of solid-state batteries.
As a next-generation energy technology, solid-state batteries are expected to expand their potential even further. However, their widespread use requires addressing safety issues, and the entire industry is being called upon to work toward resolving these issues. Nemoto Specialty Chemical Co., Ltd.'s gas sensors can help with this.
