Abstract:
Described herein are insulating structures that include at least one microporous layer including a plurality of pores, a porous layer adjacent to the microporous layer, and a monolithic aerogel structure extending through the plurality of pores of the microporous layer and through at least part of the porous layer. The microporous layer filters aerogel dust from cracked or damaged aerogel within the scaffold, slowing or preventing loss of dust from the insulating structures.

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.
Abstract:
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.

The present disclosure is directed to methods of forming lithium transition metal phosphate and fluorophosphate materials in a conductive carbon matrix. The disclosed methods are advantageous in utilizing inexpensive reactants, can mitigate formation of impurities during the synthesis, providing a more homogenous product, and may provide cathode materials with enhanced tap density relative to prior lithium transition metal phosphates. The lithium transition metal phosphate and fluorophosphate materials prepared by the disclosed methods are intimately mixed with carbon within a continuous, three-dimensional conductive carbon matrix. The materials prepared according to the disclosed methods are suitable for use in environments involving electrochemical reactions, for example as cathode materials within a lithium-ion battery.
