[0035] The working principle and use process of the present invention are as follows: when in use, the user dissolves the polymer in a suitable solvent, adds other ingredients such as ceramic fillers or sodium salt, stirs and mixes them thoroughly, and then casts the solution into the upper mold 4. The upper mold 4 cooperates with the motor 57 to merge. The motor 57 drives the turntable 58 to rotate clockwise. The rotation of the turntable 58 drives the transmission column 59 to move in a circle.

The air pump 62 works to pressurize the air into the interior of the upper mold 4 through the air inlet pipe 63. The upper mold 4 cooperates with the air channel 64 to guide the air flow into between the carrier 2 and the upper mold 4. The air flow quickly passes through and takes away the heat, so that it is quickly cooled and solidified by the volatilization of the solvent to form a composite solid electrolyte membrane. Similarly, the motor 57 works counterclockwise to drive the upper mold 4 to separate from the carrier 2 upward to achieve the demoulding effect.

[0036] In summary, the method for preparing a composite solid electrolyte for a sodium battery solves the problem that the manual mold opening efficiency is slow and the operation is time-consuming and laborious in the preparation process of the existing composite solid electrolyte by using a jig base 1, a carrier 2, a limiting column 3, an upper mold 4, a demolding mechanism 5, a convex block 51, an H-shaped plate 52, a vertical plate 53, a sliding column 54, a rectangular frame 55, a mounting seat 56, a motor 57, a turntable 58, a transmission column 59, a cooling mechanism 6, a support 61, an air pump 62, an air intake pipe 63, an airway 64 and a sealing component 7 in combination.
