Do you know the principle and composition of batteries?

  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)

p>

   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:
