Manufacturing method of sensor for testing density of electrolyte of lead-acid storage battery

Abstract

The invention discloses a method for manufacturing a sensor for testing the electrolyte density of a lead-acid storage battery. According to a Nernst equation, the electromotive force of the lead-acid battery has strict correlation with the density and temperature of sulfuric acid, a pair of polar plates can be formed by just immersing a pair of lead-based electrodes into the sulfuric acid and repeatedly performing charging and discharging; the polar plates are inserted into sulfuric acid to be tested, and so that electromotive force can be tested, meanwhile, the temperature of the sulfuric acid is measured, and the density of the sulfuric acid can be calculated according to a set program; due to the fact that the sensor directly outputs electromotive force signals, distortion errors caused by signal conversion links needed by other sensors are avoided by utilizing the existing conductivity electrodes; the electromotive force signals are easy to accurately measure; and when the sensor is used for measuring the density of the sulfuric acid, high precision can be obtained; when the sensor is not influenced by colloid coagulation when being used for dilute colloid electrolyte measurement; and in order to obtain high-quality positive lead dioxide and negative lead plates with fixed surface areas, the electrodes are firstly subjected to an electroplating reaction.

technical field [0001] The invention relates to the field of batteries, in particular to a manufacturing method of a sensor for testing the electrolyte density of a lead-acid storage battery. Background technique [0002] At present, in the process of preparing the electrolyte, the lead-acid battery needs to detect the density of the electrolyte in real time to detect the electrolyte required for the preparation. At present, the density of the main sulfuric acid is mainly tested by a density meter, weight divided by volume, and a refractometer. In production Considering the cost and convenience, the density meter is mainly used for testing at present. Using a density meter, the test process is more troublesome, and the acid density cannot be monitored online.
