Abstract

PURPOSE:To prevent the penetration of sulfuric acid into a strap to prevent the corrosion thereof by covering the strap having the connecting part of different lead alloys with polytetrafluoroethylene(PTFE) which has high water repellency. CONSTITUTION:Prior to accommodating a plate group into a container, a strap of the plate group is immersed in the dispersion of PTFE, or sprayed with the dispersion, then heated at a temperature near the melting point of the PTFE with separator damage prevented to form a film of the PTFE. By this surface treatment, the connecting part between Pb-Ca alloy and Pb-Sb alloy, where is easily corroded, is protected. If the strap is exposed from an electrolyte level, the strap is protected from the corrosion caused by O2. The penetration of sulfuric acid into the connecting part of different lead alloys existing in the strap is prevented to prevent breakage thereof. By covering the whole strap with PTFE, the elusion of Sb from the Pb-Sb alloy in the strap can be prevented.
