[PROBLEMS] To provide a thin graphite crystal ingot useful as an electrode material for lithium ion batteries, hybrid capacitors and the like, and a production method for efficiently and high productivity. [MEANS FOR SOLVING PROBLEMS] A powdered organic compound, which is calcined to contain residual hydrogen, is sealed in a graphite container and subjected to a hot hydrostatic pressure Shaped graphite crystal mass in which flake-like graphite crystals extending from the inside to outside are gathered by a treatment (HIP treatment) or the like. |
