Abstract

PURPOSE:To increase the porosity of a negative active material and obtain a negative plate for a lead storage battery having an improved utilization rate of the active material by adding polystyrene powder of given particle diameter in kneading a negative paste. CONSTITUTION:pulverized polystyrene powder with particle diameters of 1-10mu and a negative expander are added to lead oxide powder or the like before the mixture is kneaded to make a paste. The paste is then packed into a grid. The thus obtained body, after being immersed in an organic solvent to dissolve the pulverized polystyrene powder, is dried to remove the organic solvent thereby making a negative plate. According to this method, the porosity of the active material is increased. As a result, a negative plate for a lead storage battery containing a negative active material with an improved utilization rate can be easily obtained.

Description

【発明の詳細な説明】 本発明は鉛蓄電池用陰極板の製造法の改良ζこ関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method of manufacturing a cathode plate for a lead-acid battery.

させる方法が採用されてきた。Conventionally, in order to improve the utilization rate of a cathode active material, a method has been adopted in which the porosity of the active material is increased by increasing the water content of the paste.

活物質量を大幅に低減することは困難であった。However, with this method, as the water content of the paste increases, the paste softens, and the paste filled in the lattice body may deform when it leaves the filling belt of the electrode plate manufacturing equipment, or the electrode plate after the paste filling is finished. It has disadvantages such as the paste sagging during transportation. Therefore, it is impossible to significantly increase the porosity of the active material by increasing the water content of the paste, and it is difficult to improve the utilization rate of the active material and significantly reduce the amount of active material. .

ある。In view of the above points, the present invention aims to increase the porosity of a cathode active material and significantly improve the utilization rate of the active material.

次に本発明の一実施例を説明する。Next, one embodiment of the present invention will be described.

Dilute sulfuric acid having a specific gravity of 1.260 was gradually added and acid kneaded for 10 minutes, and after final kneading for 10 minutes, the grid was filled with the paste and a non-cathode plate was manufactured according to the conventional process. The unformed cathode plate or the chemically formed cathode plate is immersed in an organic solvent such as benzene to dissolve the polystyrene fine powder, and then the organic solvent is removed by vacuum drying to obtain a cathode plate.

活物質の多孔度を増大せしめることである。The feature of the present invention is that the porosity of the cathode active material can be easily increased by a simple operation of adding polystyrene fine powder of a predetermined particle size at the time of paste mixing, filling four grids with paste, and dissolving it with an organic solvent. That's true.
