A recently granted patent (Publication Number: US11658361B2) describes a battery with an insulation material made of a reinforced aerogel composition. The insulation material consists of a layer with an average thickness ranging from 1 mm to 10 mm and a thickness variation between 5% and 15%.

The patent claims that the reinforced aerogel composition can be either organic or silica-based. It further states that the composition should have a thermal conductivity between approximately 12 mW/mK and 20 mW/mK.

Additionally, the insulation material can have a layer with an average thickness of less than 5 mm and a thickness variation of less than 15%. The reinforced aerogel composition can also include inorganic, organic, or fiber reinforcement materials.

The patent also describes a battery with an insulation sheet made of a reinforced aerogel composition. The insulation sheet should have a resilience of more than 50% and an average thickness of 10 mm or less, with a thickness variation of less than 15%.

Similar to the previous claims, the reinforced aerogel composition can be organic or silica-based, with a thermal conductivity between approximately 12 mW/mK and 20 mW/mK. The resulting reinforced aerogel composition can have an average thickness of less than 3 mm or less than 5 mm.

Furthermore, the reinforced aerogel composition should have a resilience of more than 75% or more than 90%. It can also include inorganic, organic, or fiber reinforcement materials.

Overall, this patent highlights the use of a reinforced aerogel composition as an insulation material in batteries. The composition's specific characteristics, such as thickness, thermal conductivity, and resilience, are defined to optimize the performance of the battery. This innovation could potentially lead to improved battery efficiency and safety.
