November 7, 2019: NGK Insulators, the Japanese ceramics manufacturer, and BASF New Business announced today they had entered into a joint development agreement for sodium-sulfur batteries for stationary applications.
The goals are to achieve an increase in power and higher number of cycles per time unit, to open up new market segments for NAS batteries.
The JDA extends a sales partnership agreement for sodium sulfur batteries announced this June.
“Sodium-sulfur technology is ideally suited for long duration energy storage,” says Frank Prechtl, a business director at BASF. “With our envisioned technical advancements, we want to significantly broaden the application spectrum for these batteries.”
Tatsumi Ichioka, general manager of the NAS battery division at NGK said: “As we move towards the next generation of sodium-sulfur batteries, the interplay between the chemical processes taking place at battery cell level and the battery modules as a whole system becomes more and more crucial.
“BASF’s chemical expertise and our know-how in the design and production of battery modules and systems complement each other perfectly here,”
NGK’s NAS battery is the world’s first commercialized megawatt-class battery. It has the capacity to store large amounts of electricity for hours. “The NAS battery system provides an array of superior features, including larger capacity, higher energy density and longer life compared to other battery technologies,” says the firm.
“These features are beneficial for stationary applications — in contrast to lithium-ion batteries, for example, which are suited to deliver high power over shorter periods.”
