Double-layered thermal interface material structure, manufacturing method thereof, and battery device having the same

A double-layered thermal interface material structure manufacturing method, comprising the steps of:

• (1) providing a first mould comprising a first moulding recess, wherein a bottom surface of the first moulding recess is formed with M units of first protrusion member, M being an integer, and each of the first protrusion member comprising a convex surface;
• (2) filling a first thermal interface material into the first moulding recess;
• (3) disposing a supporting mesh plate in the first moulding recess;
• (4) filling a second thermal interface material into the first moulding recess, and being positioned on the supporting mesh plate;
• (5) providing a second mould comprising a second moulding recess, wherein a bottom surface of the second moulding recess is formed with M units of second protrusion member, and each of the second protrusion members comprising a convex surface;
• (6) stacking the second mould on the first mould, so as to make the second moulding recess receive the second thermal interface material;
• (7) curing the first thermal interface material and the second thermal interface material to become a layer structure;
• and
• (8) demoulding the second mould and the first mould, thereby obtaining a double-layered thermal interface material structure.
