CAN FIRE SAFETY TECHNOLOGY PREVENT THERMAL RUNAWAY

Large-capacity thermal energy storage technology

Thermal energy storage (TES) units, also called thermal batteries, use grid or onsite electricity to generate and store heat in a medium or in chemical bonds. They can charge when low-cost electricity is available during off-peak times to store heat for later consumption, up to multiple days later.
