A kind of and for example preparation method of graphite flake of Application No. 201410122837.3, including offer the first graphite flake, and
And stick first and second release base material on first and second surface of the first graphite flake, then along the of the first graphite flake
One side separates first and second release base material, and the first graphite flake is separated into second and third graphite flake in uniform thickness,
The second graphite flake after compacting separates afterwards, and stick the 3rd release base material on the parting surface of the second graphite flake after compacting,
So that along second side separation first and the 3rd release base material of the second graphite flake, and then it is equal that the second graphite flake is separated into thickness
The the 4th and the 5th even graphite flake.When the preparation method of graphite flake proposed by the invention can reduce the preparation of conventional graphite piece
Between, and also preparation flow can be simplified, reduces cost and minimizing are polluted.
Both the above preparation method all have impact on physical aspect and the chemical form of graphite flake crystal, the graphite prepared
Deviation characteristically can be deposited.
