CATHODE WITH ANODIZED LEAD CURRENT COLLECTOR

摘要

Improved cathodes for use in acid Leclanche cells, particularly of the reserve type where sulphuric acid is added to activate the cell prior to use, are constructed using an anodized lead current collector which possesses advantages over other materials in being less bulky than carbon, cheaper than platinum and giving a steadier output voltage than un-anodized lead, while still being resistant to corrosion.
