Abstract
The invention relates to a lead-acid storage battery ceramic electrode grid and a manufacturing method thereof. The ceramic electrode grid comprises lead alloy grids and a ceramic base plate, wherein the two sides of the ceramic base plate are provided with the lead alloy grids in a way of pressure casting; the ceramic base plate is provided with a through hole, each of the lead alloy grid includes lead alloy reinforcement bars and frames which form a plurality of blanks, and a connecting point is arranged between the lead alloy grids arranged at the two sides of the ceramic base plate at the position of the through hole. The manufacturing method of the ceramic electrode grid comprises the fabrication of the ceramic base plate and the pressure casting of the lead alloy grids. A battery provided with an electrode board prepared by the ceramic electrode grid passes through heavy current charge and discharge rapid detection and proves that the grid electrode board battery provided with the ceramic base plate has good uniformity and more circulation times, so as to enlarge the capacity of a storage battery and obtain longer service life.
Description
technical field [0001] The invention relates to accumulators, in particular to an electrode grid used in electrode plates of lead-acid accumulators and a manufacturing method thereof. Background technique [0002] As a mobile energy source, batteries have become an indispensable part of all walks of life. Among all kinds of storage batteries, due to the advantages of large current, high single-cell voltage, easy-to-obtain materials, and cheap prices, lead-acid batteries always occupy the first place in production and sales. Disadvantages such as large discharge, short life, low specific energy, unreliable use safety, and acid mist restrict its application in many fields. [0003] At present, with the development of the economy and the application of lead-acid batteries more and more widely, people have higher and higher requirements for the performance of lead-acid batteries. In order to improve the performance and usage characteristics of lead-acid batteries, cathode abso...
