Sodium-sulfur batteries, also known as Na-S batteries, are a type of energy storage system that uses a molten mixture of sodium and sulfur as the electrolyte.
Although sodium-sulfur batteries have existed for more than half a century, they have been an inferior alternative and their widespread use has been limited by low energy capacity and short life cycles. Dr. Zhao’s Na-S battery has been specifically designed to provide a high-performing solution for large renewable energy storage systems, such as electrical grids, while significantly reducing operational costs.
“When the sun isn’t shining and the breeze isn’t blowing, we need high-quality storage solutions that don’t cost the Earth and are easily accessible on a local or regional level.
