Title:
LEAD STORAGE BATTERY AND METHOD OF PRODUCING SAME
Document Type and Number:
Japanese Patent JPS57107575
Kind Code:
A
Abstract:
This invention is related to a method of making a lead storage battery with a thixotropic gel as electrolyte consisting substantially of a sulphuric acid and a gelling agent. The object is to provide a lead storage battery which is maintenance free, leak-proof and of a long cycle life while permitting filling of the electrolyte independently of the plate dimensions including the superficial extent of the plate. To achieve this object: (a) the sulphuric acid is electrochemically bonded in the active material of the electrodes; and (b) the gel forming electrolyte is filled into the battery in the form of a gelling agent and a sulphuric acid concentration which is insufficient for the formation of a gel, but which is sufficient for initiating a charging process upon application of a charging voltage. During the charging process the sulfuric acid that is bonded to the electrodes, together with the gel forming electrolyte, will start the formation of the gel.
