Therefore, the battery charging device has the characteristics of short charging time, long service life, good temperature characteristic, energy conservation, environmental protection and the like. The diaphragm in the capacitor battery is an important component of the battery, and the main functions of the diaphragm are as follows: the positive electrode and the negative electrode are separated, electrons in the battery cannot freely pass through the battery, and ions in the electrolyte freely pass through the positive electrode and the negative electrode, so that the ion conduction capability of the diaphragm is directly related to the overall performance of the battery. In order to improve the safety performance of the battery, a ceramic coating is required to be coated on the surface of the separator to improve the heat shrinkage resistance of the separator and prevent the separator from shrinking to cause large-area short circuit. The existing battery diaphragm coating equipment mainly adopts a coating roller to roll on a diaphragm substrate for coating, but the contact area of the coating roller and the diaphragm substrate is small, so that the phenomenon of uneven coating is easily caused, and the diaphragm substrate can pass through a guide roller and is conveyed to a drying mechanism after being coated.
