DEVELOPMENT OF SODIUM/SULFUR BATTERIES. PHASE 4. FINAL REPORT

ENTWICKLUNG VON NATRIUM/SCHWEFEL-AKKUMULATOREN. PHASE 4. ABSCHLUSSBERICHT

The objective of this project was to promote the further development of the sodium/sulfur-battery to a state that the use in applications such as electric vehicles and stationary energy storage can be demonstrated. Within this period it was possible to double the energy ddensity of batteries (at 2h-discharge) from 46 Wh/dm (3) to 98 Wh/dm (3) and to augment peak power density from 42 W/dm (3) to 170 W/dm (3) This increse is a result of improvements of the cells (180 Wh/kg resp. 300 W/kg) and the battery design. Tests with batterieswere carried out in the laboratory, in electric vehiocles accumulating a total distance of more than 80,000 km and in a low voltage energy store with a series of connection of six batteries. The experiences of these tests necessitate changes in the cell and the battery which could not be implemented into the production of the batteries before the end of the project.
