The current disclosure provides reinforced aerogel compositions that are durable and easy to handle, have favorable performance in aqueous environments, 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 an open-cell macroporous framework, and includes one or more fire-class additives, where the silica-based aerogel framework comprises at least one hydrophobic-bound silicon and the composition or each of its components has desired properties.

Fire-class reinforced aerogel compositions

Battery thermal management materials, compositions and systems are provided. Exemplary embodiments include a battery thermal management member. The battery thermal management member can include a heat protection layer and a resilient layer. Also provided are methods of preparing or manufacturing such battery thermal management members. In certain embodiments, the heat protection layer can include mica, microporous silica, ceramic fiber, mineral wool, aerogel or combinations thereof.

Battery thermal management member

Components and systems to manage thermal runaway issues in electric vehicle batteries 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.

Components and systems to manage thermal runaway issues in electric vehicle batteries

The present invention relates to a thermal insulation board (IB) comprising at least two insulating layers (A) bonded together. At least one of the at least two insulating layers (A) comprises at least one aerogel composite material, wherein the aerogel composite material comprises at least one silica aerogel (a1), at least one polymer foam (a2) and at least one flame retardant (a3). The present invention also relates to a thermal insulation system (IS) comprising the thermal insulation board (IB). Further, it relates to a process for the production of the thermal insulation board (IB) and to the use of the thermal insulation board (IB) and of the thermal insulation system (IS) for the thermal insulation of buildings, parts and/or elements of buildings.

Thermal insulation board comprising at least one aerogel composite material for the thermal insulation of buildings

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.

Devices, systems, and methods for controlling vent gases and ejecta from thermal runaway events in energy storage systems

The present disclosure relates to methods and systems to manage thermal runaway issues in energy storage systems. Exemplary embodiments include methods and systems having a compressible thermal barrier. The compressible thermal barrier is tailored in size (e.g., thickness, volume, etc.) to prevent thermal propagation between adjacent cells, modules and/or packs when a portion of an energy source has experienced a thermal event. The methods and systems mitigate thermal propagation such that a cell adjacent to a compromised cell (e.g., actively combusting cell) does not experience thermal runaway as it is shielded from dissipating heat and does not surpass a critical temperature. The present disclosure further relates to a battery module or pack with one or more battery cells and the compressible thermal barrier placed between adjacent cells.

Systems and methods for mitigating thermal propagation in battery-based energy storage systems

This disclosure relates generally to aerogel technology. The disclosure relates more particularly, in various embodiments, to improved methods for producing aerogels and improved aerogel composites having a low compression set.

Low compression set aerogels and aerogel composites and methods of making

The present disclosure can provide an aerogel composite. The aerogel composite comprises at least one base layer having a top surface and a bottom surface, the base layer comprising a reinforced aerogel composition which comprises a reinforcement material and a monolithic aerogel framework, a first facing layer comprising a first facing material attached to the top surface of the base layer, and a second facing layer comprising a second facing material attached to the bottom surface of the base layer. At least a portion of the monolithic aerogel framework of the base layer extends into at least a portion of both the first facing layer and the second facing layer. The first facing material and the second facing material can each comprise or consist essentially of a non-fluoropolymeric material.
