Abstract: A humidity control module includes a humidity control layer configured to absorb or release water vapor, a first gas-permeable layer arranged in a stacked manner on a surface of the humidity control layer and capable of allowing passage of water vapor and preventing passage of liquid water, a second gas-permeable layer arranged in a stacked manner on a surface of the first gas-permeable layer facing away from the humidity control layer and capable of allowing passage of water vapor and liquid water, and a fixing layer arranged on a side of the humidity control layer facing away from the first gas-permeable layer and configured to fix the humidity control layer, the first gas-permeable layer, and the second gas-permeable layer to a carrier.

Abstract: A device and method for preparing an aerogel blanket, are described. The device for preparing an aerogel blanket includes: a first transport means configured to transport a blanket substrate; a first spray means configured to spray a sol to the blanket substrate on the first transport means; a second transport means arranged downstream of the first transport means and configured to transport the blanket substrate sprayed with the sol; and a second spray means configured to spray a gel catalyst to the blanket substrate on the second transport means. The device and the method for preparing a aerogel blanket can improve the preparation efficiency of the aerogel blanket.

Abstract: A heat insulation pad and method of making the same, battery assembly and device are provided. In some embodiments, the heat insulation pad includes silicon rubber and aerogel dispersed in the silicon rubber, wherein the heat insulation pad satisfies that: a temperature difference between a surface on one side of the heat insulation pad and a surface on the other side opposite to the one side is ?150° C., when the surface on one side of the heat insulation pad is contacted with hot surface having a temperature of 600° C. for 5 minutes under a pressure of 0.9 MPa followed by pressure relief and then is contacted with hot surface having a temperature of 600° C. for another 20 minutes. By using the heat insulation pad of the present disclosure, the safety performance of the battery assembly and of the device can be improved.
