摘要： The present disclosure relates to materials and systems to manage thermal runaway issues in energy storage systems. Exemplary embodiments include an insulation layer that is encapsulated to form an insulation barrier. A support member is placed around at least a portion of an insulation layer. The support member provides a support for the insulation layer, allowing the insulation layer to be easily encapsulated and installed in a battery module or pack.

摘要： Aerogel-based components and systems for electric vehicle thermal management are provided. Exemplary embodiments include a heat control member. The heat control member can include reinforced aerogel compositions that are durable and easy to handle, have favorable performance for use as heat control members and thermal barriers for batteries, have favorable insulation properties, and have favorable reaction to fire, combustion and flame-resistance properties. Also provided are methods of preparing or manufacturing such reinforced aerogel compositions. In certain embodiments, the composition has a silica-based aerogel framework reinforced with a fiber and including one or more opacifying additives.

摘要： The present disclosure relates to materials and systems to manage thermal runaway issues in battery modules. In exemplary embodiments, a battery module includes battery cells separated by spacer elements. To mitigate thermal runaway issues, spacer elements may be extended to the interior surface of the enclosure. A seal is formed between the spacer elements and the interior wall to form a thermal barrier between adjacent battery cells.
