Glass powder for electrode paste, electrode paste, preparation method and battery

The invention discloses glass powder for electrode paste, the electrode paste, a preparation method and a battery, relates to the technical field of crystalline silicon solar batteries, and aims to overcome the defects of poor adhesion of the electrode paste on the surface of a conductive material of the battery and high lap resistance of the electrode paste and the surface of the conductive material of the battery. The glass powder comprises a main glass component and an auxiliary glass component with wettability to a conductive material, the mass part ratio of the main glass component to the auxiliary glass component is (1.5-4.5): (0.15-0.25), and the wetting angle of the auxiliary glass component in a molten state on the conductive component is larger than 0 degree and smaller than 90 degrees. The invention discloses glass powder for electrode paste, the electrode paste, a preparation method and a battery. The glass powder is used for preparing the electrode paste. 本发明公开一种电极浆料用玻璃粉、电极浆料及制备方法和电池，涉及晶硅太阳能电池技术领
