The utility model discloses a IBC battery electrodes structure, wherein prepare at the back of IBC battery has P district and N district, the preparation has just superfine grid line and anodal main grid section in the P district, the preparation has thin grid line of negative pole and negative pole main grid section in the N district, just superfine grid line, anodal main grid section, the thin grid line of negative pole and negative pole main grid section are the electroplating electrode, anodal main grid section with negative pole main grid duan jun lies in the inside of IBC battery piece,just anodal main grid section only with just superfine grid line mutually perpendicular electric connection, negative pole main grid section only with the thin grid line mutually perpendicular electric connection of negative pole. Because between anodal main grid section and the thin grid line of negative pole and insulating naturally between the superfine grid line of negative pole main grid duanyuzheng, insulating cement and silver -colored application of starching have been cancelled in the event, have reduced the battery preparation cost.
