摘要
The present invention relates to multilayer composite materials with anisotropic thermal conductivity for high safety pack design. According to the present invention, the multilayer composite material has a sandwich structure, and comprises: an inner layer consisting of an aerogel material which has ultra-low thermal conductivity; and two thermal conduction layers which contain graphene based nano carbon and possess high thermal conductivity, wherein the inner layer is sandwiched by the two thermal conduction layers. When used as a spacer between two neighbor cell, the multi-layer composite material can help to achieve uniform thermal distribution, stop the thermal propagation and act as a spacer to accommodate the volumetric change during charge and discharge.
