抄録

Sodium-Sulfur Batteries have been developed to provide load-leveling and stabilize the supply of electricity for electric utilities and large customers. However, concern for safety increases with the amount of sodium and sulfur required for commercial products. The latest (and largest) is a 50kW, 400kWh battery module comprised of 384 cells, designated "T5" cells. Safety is ensured by rigorous safety tests to verify performance during accident conditions that cause electrical, mechanical, thermal and chemical hazards. These tests have proven that T5 cell and 50kW module are adequately safe during such events for use in commercial applications.
