Embodiment 1
[0019] The step of adopting the inventive method to prepare SP / graphene conductive paste is as follows:
[0020] Step 1: Dissolve 1g of PVP (polyvinylpyrrolidone) in 95g of NMP (N-methylpyrrolidone) and vibrate ultrasonically to form a homogeneous solution;
[0021] Step 2: 1g of graphene and 3g of SP (conductive carbon black) are added to the above solution, stirred and mixed with a glass rod to obtain a graphene suspension with a solid content of 5.0wt%;
[0022] Step 3: Ultrasonic vibration treatment is performed on the suspension to prepare the initial graphene conductive paste. Ultrasonic time: 30min;
[0023] Step 4: Transfer the initial conductive paste to a high-speed shear emulsification homogenizer for shear dispersion to obtain a uniform and fully dispersed graphene conductive paste. The frequency is 30HZ, and the cutting time is 30min.
