9/28/2023 0 Comments Murata solid state batteryAchieving Both Safety and High Performance by Combining Murata's Proprietary Materials Technology with MLCC Technology This prototype was unveiled at CEATEC 2019 and was awarded the CEATEC AWARDS 2019's Minister of Economy, Trade and Industry Award, and it has continued to attract growing attention. In 2019, Murata successfully developed a solid-state battery that satisfied the highest industry performance standards. As a part of this effort, Murata is drawing on its long history of development in multilayer ceramic capacitor (MLCC) technology to develop proprietary materials, processes, and equipment technology. ("Murata" below), we are developing solid-state batteries that boost the storable power to the maximum possible while ensuring safety as our utmost priority for contributing to the realization of compact, high-performance IoT devices and wearables. Aiming for Solid-state Batteries Capable of Supporting Further Advances in IoT Devices and WearablesĪt Murata Manufacturing Co., Ltd. *1: An electrolyte is a substance that serves as the path for charges and interchanging media (lithium ions in the case of a lithium-ion secondary battery) to move between the positive and negative electrodes inside secondary batteries which can charge and discharge power. Development is being conducted on sulfide-based solid electrolyte materials which can provide high output, but when the sulfide-based material is exposed to air, toxic gas can be generated. However, the solid electrolyte materials that have been used previously in solid-state batteries for high safety had a drawback where the ions did not flow easily within the battery, and this adversely affected the high performance of the lithium-ion secondary batteries. To resolve these issues, development is being conducted around the world on solid-state batteries where the electrolyte *1, which was a flammable liquid in lithium-ion batteries, is changed to a non-flammable solid material for enhanced safety. For this reason, lithium-ion batteries require various types of limitations and protective measures when using under harsh environments, in equipment critical to human life, or in equipment that handles valuable assets. Also, if a lithium-ion battery is subjected to an external impact, a short-circuit could occur within the battery, causing it to overheat, and in the worst case, it could even ignite. ![]() The material components of lithium-ion secondary batteries include flammable liquids. However, there are strong calls for even higher safety in today's lithium-ion secondary batteries so that they can be used in mobile electronic devices for even wider applications. Because they can store a large amount of power in a small space and can charge and discharge at high output, lithium-ion secondary batteries provide a high level of performance for mobile electronic devices far beyond any other types. Across the board, smartphones and similar devices use large amounts of power. Issues with High-Performance Lithium-ion Secondary BatteriesĬurrently, lithium-ion secondary batteries are the most widely used batteries for mobile electronic devices. However, further advancements in batteries are vital for realizing widespread use of these IoT devices and wearables. Wearables are also expected to become widespread for maintaining our health and enriching our lifestyles. ![]() To accurately assess the operating status of social infrastructure, factories, and other locations, compact IoT devices are essential for collecting on-site data and transmitting it to a data center. Advancements in batteries for these devices have been a key driver in enabling use of these mobile electronic devices for a wider range of applications.īefore we can reach a fully data-driven society, mobile electronic devices must be designed in even more compact sizes and lightweight designs. Murata's Oxide-based Solid-state Batteries for Expanding the Range of Applications for IoT Devices and Supporting More Advanced Wearables (Part 1 of 2) Īiming for Further Evolution of Mobile Electronic Devicesĭue to tremendous advances in semiconductors and chip components, mobile electronic devices such as smartphones and notebook computers have become an essential part of our everyday lives and our work.
