During the last few years graphite intercalation compounds have attracted a great deal of attention, particularly because of their promise as materials of high conductivity and anisotropy, especially Graphite-FeCl₃ intercalation compound (GIC-FeCl₃) owing to its extensive usage in high density lithium ion Batteries and other commercial applications. Various research has been published that experimentally investigates its physical and electronic properties from battery perspective. But what’s globally missing is a critical investigation of its nanoscale thermal properties mainly temperature and size dependance of a) in-plane and cross-plane thermal conductivity b) thermal boundary conductance c) heat capacity, etc. Herein, we demonstrate first ever step towards fabrication and characterization of thermal properties of micrometer sized GIC-FeCl₃. Ultrafast femtosecond laser based TDTR will be employed to characterize thermal conductivity, thermal boundary conductance and specific heat capacity of the micrometer sized GIC intercalated flake.
