Embodiment Construction

[0018] refer to figure 1 and figure 2 , one aspect of the disclosed containment device for an energy storage device, generally indicated at 10 , may include a protective cover 12 and a seal 14 . Protective cover 12 may define an interior volume 16 and an opening 18 that may provide access to interior volume 16 . Seal 14 may be configured to seal opening 18 such that energy storage device 20 may be enclosed within interior volume 16 .

[0019] Opening 18 and seal 14 may be configured to allow wires or the like to extend through opening 18 so that energy storage device 20 may be discharged when enclosed within receptacle 10 . Optionally, additional ports (not shown) through the protective cover 12 may be provided to facilitate electrical connections.

[0020] Energy storage device 20 may be any device capable of storing electrical energy, such as a battery. In one specific aspect, energy storage device 20 may be a high energy density battery, such as a lithium ion battery. ...

Abstract

A containment device including a cover defining an internal volume and an opening into the internal volume, the cover being formed as a layered structure including at least a first layer and a second layer, the first layer comprising a woven ceramic fabric and the second layer comprising oxidized polyacrylonitrile fibers.

Description

technical field [0001] This patent application relates to safety devices and methods for containing energy storage devices, and more particularly to devices and methods for containing energy released from energy storage devices during thermal runaway. Background technique [0002] High energy density energy storage devices are capable of storing relatively high amounts of electrical energy per unit mass. For example, a lithium-ion battery may be able to deliver 150 watts per kilogram of battery. In contrast, lead-acid batteries may only be able to deliver 25 watts per kilogram of battery. Therefore, high energy density energy storage devices are of particular interest when overall weight is a consideration, such as on commercial aircraft and personal electronics. [0003] However, thermal runaway is an important challenge for high-energy-density energy storage devices, such as lithium-ion batteries. During thermal runaway of a Li-ion battery, exothermic reactions generate...
