Sodium, the troublemaker that reacts violently with water, and sulfur, the plain and difficult one. Two dangerous loners become grid-scale energy storage when paired. The Na-S battery operates only at 300–350°C — a person who shines in serious mode. Quiet by default, but stores immense energy and releases it overwhelmingly, separated by a β-alumina electrolyte at the perfect distance.
