2) traditional diaphragm that generates heat adopts electrically conductive silver thick liquid as electrode material, and under the loading high pressure condition, the diaphragm calorific capacity increases, and the deformation appears in diaphragm supporting material, because silver thick liquid drying condenses the back, has the silver thick liquid gathering condition, leads to electric conductive property unstable, and mechanical tensile properties is poor simultaneously, causes electrode and busbar junction to appear the crack, and then the fracture, causes the diaphragm to become invalid.

The creepage effect of the diaphragm under the high-voltage condition is effectively solved; in the film pasting process, the terminal is burnt due to the warping of the electrode terminal, and the phenomenon is caused by the fact that the temperature of the terminal is too high and the terminal is damaged at the earliest because the graphene is directly contacted with the terminal;
