COATING TYPE LEAD DIOXIDE ELECTRODE

摘要

PURPOSE:To improve adhesiveness, strength, dimensional stability and electricity conduction capacity and to facilitate production by coating lead dioxide via intermediate layers on a blanked plate which is specified in the diameter and thickness of the blanked parts. CONSTITUTION:The blanked plate of which the max. diameter of the blanked parts and the shortest spaces between the adjacent blanked parts are respectively 1.5-12mm and 1.5-7.0mm and the thickness is 1.0-7.0mm is prepd. The intermediate layers 2 consisting of an acid resistant and conductive platinum group (alloy), etc. are coated on the plate 1. The lead dioxide layer 3 is coated to about 0.3-8mm thickness over the entire surface of the layers 2 to form electrodes. The coating type lead dioxide electrodes exhibit substantial durability against a corrosive electrolyte. There is no need for a welding stage in production and the increase of the size to some extent is possible.
