Abstract
A graphite material includes a plurality of graphite particles and a plurality of pores. The plurality of graphite particles and the plurality of pores form a microstructure. A ratio of an elastic modulus to a compression strength of the graphite material ranges from 109 to 138. Preferably, a ratio of a total area of the pores to a whole area of the graphite material in a cross-section of the graphite material ranges from 17.94% to 19.97%.
