BASF and NGK to partner on developing the next generation of sodium-sulfur batteries

BASF New Business GmbH, a wholly owned subsidiary of the German chemical company BASF, and Japanese ceramics manufacturer NGK INSULATORS, LTD. are expanding their cooperation. In addition to the sales partnership agreement for NAS® batteries announced in June 2019, they have now entered into a joint development agreement (JDA) to develop the next generation of sodium-sulfur batteries.

This JDA will exploit the synergy in know-how of both companies, BASF and NGK. The two companies aim to develop the next generation of sodium-sulfur batteries, making use of BASF’s extensive chemistry expertise and NGK’s expertise in battery design and manufacturing. The project will allow to expand the performance range of NAS batteries and thus open up new markets.

“Thanks to its unique properties, sodium-sulfur technology is ideally suited for the steadily growing market for long duration energy storage. With our envisioned technical advancements, we want to significantly broaden the application spectrum for these batteries,” says Dr. Frank Prechtl, Director Business Build-Up E-Power-Management at BASF New Business GmbH.

“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,” adds Tatsumi Ichioka, General Manager of the NAS battery division at NGK.
