The utility model discloses a glass sealing structure of a battery electrode post. The sealing structure comprises a lower glass gasket, a battery cover plate, an upper glass gasket, a gasket fixing piece, a fixing ring and a welding flux ring which are sequentially sleeved on an electrode aluminum core column, Annular gaps which are approximately equal in diameter are formed among the glass lowergasket, the battery cover plate, the glass upper gasket and the electrode aluminum core column, and the annular gaps are filled with sealing glass. The battery electrode post glass sealing structurehas good thermal shock resistance and mechanical shock resistance, sealing operation is completed at a time, and the battery electrode post glass sealing structure is simple and efficient.
