Do you know the principle and composition of batteries?

by：Power Kingdom 2021-07-14

　　Chemical principle

　　The equation is as follows:

　　The overall reaction: Pb(s)+PbO2(s)+2H2SO4(aq) Reversible symbol 2PbSO4(s)+2H2O(l)

When discharging: negative Pb(s)-2e-+SO42-(aq)u003dPbSO4(s)

　　正PbO2(s)+2e-+SO42-(aq)+4H+(aq)u003dPbSO4(s)+2H2O(l)

　　Total Pb(s)+PbO2(s)+2H2SO4(aq)u003d2PbSO4(s)+2H2O(l)

　　 Electrolytic cell during charging

　　 cathode PbSO4(s)+2e-u003dPb(s)+SO42-(aq)

　　 anode PbSO4(s)+ 2H2O(l)-2e-u003dPbo2(s)+SO42-(aq)+4H+(a

　　Note (the cathode during charging is the cathode during discharge)

　　Physical composition

　　The main components that make up the lead battery are as follows:

　　 anode plate (Lead peroxide.PbO2)--->active material

　　 cathode plate (sponge lead.Pb)--->active material

< /p>

　　 Electrolyte (dilute sulfuric acid)--->Sulfuric acid (H2SO4) + distilled water (H2O)

　　 battery case and cover (PPABS flame retardant)

　　 isolation plate (AGM)

　　**valve

　　 positive and negative Poles, positive and negative poles, etc.

　　 physical quantity connection

　　 power and voltage relation

< /p>

　　The remaining power of the battery can be roughly obtained by measuring the battery voltage. The relationship between the voltage of the 12V lead-acid battery for vehicles and the remaining power is shown in the following table:

　　Voltage (v) remaining power

　　12.7***

　　12.590%

　　12.480%

　　12.370%

　　12.260%

　　12.150%

　　11.940%

　　11.830%

　　11.620%

　　11.310%

　　10.50%
