Mammal-Skin-Inspired Adaptive Nanocomposites Cooling Membrane for Passive Battery Thermal Management.

ABSTRACT: Efficient and flame-retardant thermal management of lithium-ion batteries (LIBs) is drawing increasing attention. Herein, we report a mammal-skin-inspired self-adaptive hygroscopic nanocomposite cooling membrane that dissipates heat from LIBs via moisture desorption and subsequently recovers its cooling capacity through spontaneous moisture absorption from ambient air. The multifunctional cooling membrane, comprising hygroscopic salt, graphene oxide, active carbon fiber, an anticorrosion copper frame, and a porous membrane, is fabricated and systematically characterized, exhibiting both outstanding cooling performance and excellent flame retardancy. Proof-of-concept experiments demonstrate that the self-adaptive cooling membrane is able to achieve an average cooling power of 802.5 W m
