A thermal management system for a plurality of batteries aligned along a common stacking axis, said thermal management system comprising at least one heat exchange member, wherein each of said at least one heat exchange member is placed in thermal communication between two adjacent batteries of said plurality of batteries and each of said at least one heat exchange member comprises a polymeric flexible substrate and at least one graphene layer disposed thereon such that said polymeric flexible substrate functions as a thermal barrier between said adjacent batteries aligned along said stacking axis such that a majority of heat being conveyed from said adjacent batteries to an external heat sink passes through an in-plane direction formed within said at least one graphene layer.
The thermal management system of claim 1, wherein said heat exchange member and said adjacent batteries comprise a substantially planar construction such that an adjacently-facing relation is formed between them.
The thermal management system of claim 1, wherein the thermal conductivity along an in-plane dimension of said heat exchange member is at least about 1000 W/m-K and said thermal conductivity along its thickness dimension is less than about 100 W/m- K.
The thermal management system of claim 1, further comprising a thermal pathway coupled to said heat exchange member to facilitate the conveyance of said majority of heat to said external heat sink.
