Description

Energy storage device

Technical Field

The present invention relates to an energy storage device.

Background

With the improvement of environmental awareness and the development of energy technology, lithium ion batteries are widely applied to large-scale energy storage devices due to environmental protection and superior performance. Such large energy storage devices are typically high in energy density and compact, and once a portion of the cells fire, the fire may be exacerbated by the exothermic chemical reaction of the lithium ion cells themselves and may burn back toward other cells. Therefore, such large energy storage devices are difficult to control fire through fire protection systems with serious safety concerns.
