PROBLEM TO BE SOLVED: To provide a flaky graphite crystalline mass and the like which are useful as an electrode material of a lithium ion battery, a hybrid capacitor and the like, and to provide an efficient and highly productive production method of them.SOLUTION: In a production method of a flaky graphite crystalline mass and the like formed by assembling of flaky graphite crystals extending from the inside to the outside, a particulate matter of an organic compound calcined so as to include residual hydrogen is sealed in a container made of graphite, and is subjected to a hot hydrostatic pressure application treatment (HIP treatment) using an atmosphere pressurized together with the container and the like in a predetermined condition. |
