* Molded Graphite: The molding method is to load a certain amount of paste into a mold having a desired shape and size and then press it from the upper or lower portion. Molded graphite has a wide range of properties in terms of mechanical strength, abrasion resistance, density, hardness, electrical conductivity, etc., and can be further improved by impregnating a resin or a metal.

3 Thermal Properties of Graphite for High Temperature

Graphite's most notable, and most unique property, has to be its incredible thermal properties. Not only does it conduct heat very well, but it also has impressive CTE values (coefficients of thermal expansion), and the material is very difficult to melt ~ yielding an intensely high melting point.

Electrochemical and thermal properties of graphite

Thermal reactions between a lithiated graphite electrode and an ionic liquid-containing electrolyte are investigated with differential scanning calorimetry (DSC). The introduction of an ionic liquid can effectively reduce the exothermic heat evolution from the thermal reactions between a lithiated graphite electrode and an electrolyte.
