Electrode grids for lead storage batteries comprise a lead alloy which, in addition to calcium and tin and, if appropriate, silver, contains of aluminum, the aluminum content being in the range of approximately 0.012% to 0.02% by weight, and the average grain diameter in the web and frame area of the grids is 200 &mgr;m-600 &mgr;m. Preferably, the aluminum content is in the range of approximately 0.014% to 0.02%, the calcium content is approximately between 0.04 and 0.06%, the tin content is approximately between 0.5 to 1.0%, and optionally 0.5 to 0.7%, and the silver content is approximately between 0.005 and 0.06%.
