Industry has also obtained rapid development.
Lead-acid accumulator is a kind of device that chemical energy is converted into electric energy, belongs to secondary cell.Charging process is by electric energy
Chemical energy is converted into be stored in active material；During electric discharge, the chemical energy being stored in active material is converted into electric energy.Electric discharge
When, positive pole PbO2It is converted into PbSO4, active material volumetric expansion, although being converted into the bigger PbSO of volume4, due to negative electrode active
Material is softer, it is easier to compresses, negative pole does not have the tendency expanded.Positive plate PbO2Relatively difficult compression, after repeated charge,
Positive plate between continuously expansion causes active material repeatedly adhesion die down, until breaking releasing, form isolated island particle.
Actual use process, battery softening degree is different, and very thin one layer of some polar board surfaces softens, and what is had is soft
Change degree is deeper, and overall activity material all softens.During failure cause is carried out to battery and searches analysis, the boundary of softening degree
Surely the process improving measure of actual production is influenced whether.In addition, softening degree be also judge battery quality quality one it is important
Factor.Therefore, the detection of pole plate softening degree is significant.
Publication No. CN105140578A Chinese invention patent discloses a kind of detection lead acid battery positive electrode active matter
The method of matter softening degree, comprises the following steps：(1) battery is dissected, takes out the positive plate for needing to test；(2) positive plate is done
After dry, weigh, record weight is M1；(3) dried positive plate is immersed in distilled water, sonic oscillation processing a period of time；
(4) positive plate is taken out, dries, weigh, record weight is M2；(5) the softness number X, X=of positive active material is calculated
(M1-M2)/M1.This method in ultrasonic vibration processing and then the quality proportion to drop by positive plate by characterizing positive plate
Softening degree, the inside lead plaster of concussion process positive plate are shaken as the lead plaster on surface so that concussion process drops
Some is probably due to the loosening between active material caused by detection process to quality, rather than lead accumulator actually uses
During cause pole plate to soften, loosened so as to combine between active material.
