![]() Smart Energy Week Autumn 2022: Battery-related Technologies (Sep. ![]() 2022)Īnalysis Report: Lithium-Ion Battery (Chinese Market) (May. Tsukasa Takahashi, Deputy General Manager of Mitsui Mining's Business Creation Sector gave a presentation at the 9th BATTERY Japan in Osaka, explaining the advantages and disadvantages of each sulfide material and the characteristics of argyrodite.Īnalysis Report: Lithium-Ion Battery (Japanese, European, North American and Korean Markets) (Nov. (Mitsui Mining) developed the argyrodite-type electrolyte that is the material for this. (Maxell) will take the lead in introducing sulfide solid electrolytes to the market in 2023. in engineering at the same university, he emphasized that there are still many issues to be resolved before widespread adoption. ![]() In a presentation given at the 15th Automotive World (January 2023) by Professor Ryoji Kanno, Ph.D. The recent surge in the topic of all-solid-state batteries was triggered by the sulfide electrolyte developed by the collaboration of Toyota Motor Corporation and the Tokyo Institute of Technology, which had a tremendous impact on the spread of research. Information on these solid-state batteries was collected through the websites and presentations by the companies involved through January 2023, as well as through coverage of the following exhibitions. Therefore, even if the quantities were large, those supplied for prototype and demonstration purposes are not treated as mass production. Note: In this report, mass production is defined as the state in which cells can be supplied on a commercial basis. In addition, as the movement toward adoption in passenger BEVs is particularly active, this report summarizes the plans announced by each automaker and outlines the products of all solid-state battery suppliers involved in those plans. This report focuses on mass-produced lithium-ion solid-state batteries, regardless of their application. However, it is the start-ups that are leading the way to mass production for EV applications, and the major automotive battery makers have either proposed a later date or have not stated their commitment at this time. ![]() This is because there are many advantages unique to solid-state batteries, and many different technologies, including "semi" solid-state batteries, have been proposed. By putting in place a production system capable of providing a stable supply of highly reliable products, Murata is contributing to the realization of a world in which everyone can safely utilize electronic devices under all sorts of environments,” said Norio Nakajima, Representative Director, Senior Executive Vice President and Director of the Module Business Unit.Although the Toyota/Tokyo Institute of Technology collaboration and Hitachi Zosen, which were expected to lead the world in the mass production of all-solid-state batteries, have postponed their material development schedules, an increasing number of semi-solid-state/all-solid-state batteries (hereafter referred to as solid-state batteries) have been launched by other companies. “The new product brings together multiple Murata technologies to deliver substantially larger capacity than previously developed solid-state batteries. The new battery also delivers safety and durability far superior to conventional lithium-ion secondary batteries, making it ideal for hearable devices such as wireless earphones that require a high degree of safety and are intended to be used for extended periods of time, as well as a good match for the diverse needs of the emerging IoT society. The battery employs an oxide ceramic electrolyte instead of the electrolytic solution utilized in conventional batteries, making it noncombustible and strongly heat-resistant.Ĭombining compact size and high energy density while delivering excellent performance even in harsh environments, the solid-state battery will contribute to the realization of new wearable devices that are smaller and more reliable than was previously possible. The development of the solid-state battery involved integrating process technology used in Murata’s main products, such as multilayer ceramic capacitors and other multilayer devices, and diverse materials technology amassed through the development of cutting-edge electronic components. has developed an solid-state battery with industry’s highest energy density.
