Title: Manufacture of negative plate for sealed lead storage battery
Inventor: HIRAKAWA TAKESHI
IPC: H01M4/23
Filed: 1983-06-21
Abstract: PURPOSE:To obtain negative plates having an effect equal to that achieved by partial electric discharge by exposing a part of each negative plate in which formation is completed outside electrolyte so as to cause the part to react with oxygen contained in air and sulfuric acid used as a formation liquid to make a sulfate salt. CONSTITUTION:During the formation, positive plates and negative plates 1 are arranged alternately. After the formation is completed, the positive plates and part of electrolyte 3 are removed from a formation container 2 thereby causing a state as shown in the upper figure. When this state is left as it is, at first oxygen contained in air reacts with lead contained in an active material to make lead oxide which then reacts with sulfuric acid working as a formation liquid and creeping up to the negative plates 1 to make lead sulfate. The speed of lead sulfate formation varies according to the temperature of the formation liquid, atmospheric temperature, the thickness of the negative plates 1 and the like. When a 30mm. portion of the plate of 100mm. width, 120mm. height and 2.2mm. thickness containing 135g of the active material is exposed to the atmosphere, a relationship shown in the lower figure is observed between the amount of lead sulfate produced in the center of the exposed portion and the time of the leaving.
