What is it about?
The paper compares electrical conductivity, texture and microstructure of graphite foils produced by rolling and by pressing. It reports directional conductivities measured in the rolling (RD), transverse (TD) and normal (ND) directions, demonstrates stronger basal-plane orientation and markedly higher in-plane conductivity for rolled foils, and links anisotropy and absolute conductivity.

Why is it important?
From my perspective, the study provides a quantified process–structure–property relationship showing how forming route influences crystallographic texture and therefore anisotropic electrical transport in product-scale graphite foils. These quantitative metrics are directly useful when selecting manufacturing parameters, designing electrical contacts or seals, and when correlating microstructural descriptors with functional transport performance.
Perspectives
Evaluate how the observed in-plane anisotropy affects contact resistance and current spreading in typical assemblies and test surface treatments or interlayers that mitigate anisotropy-driven performance loss. Use the demonstrated link between forming method and texture to tune rolling regimes aimed at enhancing in-plane conductivity while controlling porosity.
