We recently reported a new way to prepare tailor-made carbon materials by mechanical grinding 3, 4(using two types of mechanical interactions: shock or shear). In addition, this new technique allows to prepare carbon samples able to reversibly intercalate two lithiums per six carbons (e.g., Li 2 C 6 ) while having irreversible capacities of 320 mA h/g …

Thermal shock is caused by nonuniform heating or cooling of a uniform material, or uniform heating of nonuniform materials. Suppose a body is heated and constrained so that it cannot expand. When the temperature of the material increases, the increased activity of the molecules causes them to press against the constraining boundaries, thus setting up thermal stresses.
