A sealing glass is provided for the production of glass-to-metal seals, especially for battery headers, in storage batteries having a lithium electrode. The constituents of the glass, expressed in % by weight on an oxide basis, comprise: -16-25 SiO2 0-8 Li2O 0-4 MgO -20-35 B2O3 0-5 Na2O 5-12 CaO -15-24 Al2O3 0-10 K2O 10-30 BaO + SrO - 4-15 SIGMA alkali oxide 0-5 ZnO - 15-40 SIGMA alkaline- - earth oxide + - ZnO - The coefficient of thermal expansion of the glass is closely matched to the metals in the cell housing. This glass also has a good welding strength and corrosion resistance, as well as satisfactory hydrolytic resistance.
