Lead storage battery?

Question

Can anyone specifically tell me what ahppens when a lead storage battery is recharged?

Answer 1

Basically you Lead (Pb), water (H2O), and sulfuric acid (SO2). In each cell of the battery there are several layers of positive and negative plates. Some will even have a cloth or asbestos barrier to prevent bridging (when particulates build up between the plates shorting them and there by reducing the cell efficiency). It's a simple chemical equation:
Pb+SO2+3H2O charged = PbSO4+H2O+2H2
What you're doing is re-exciting the positive plates from the negative plates.

Answer 2

The connection between the terminals on a lead acid battery is an electrolyte - in the case of a vehicle battery, it is water (H2O) and sulfuric acid (H2SO4).
When the battery discharges, lead sulphate is formed on the plates and the chemical reaction caused by the electrolyte ceases - i.e. the battery is "dead." It will no longer produce an excess of electrons on the negative terminal because the chemical reactants are all "used" up - the chemical reaction is finished.
Note: If the battery is allowed to remain discharged for a long period of time, the lead sulphate formed on the plates will crystallize and the battery will be permanently damaged.
When we recharge the battery, we force a reversed electric current into the battery which causes a chemical reaction that restores the electrolyte to its charged state - ready to recombine once again with the lead to produce the current flow.

Answer 3

When a battery discharges, lead sulfate builds up on the plates. When the battery is recharged, the sulfate is driven back into solution as sulfuric acid. Sulfuric acid is heavier than water. This is why a hydrometer floats higher on the electrolyte in a charged battery.

Answer 4

there is 2 types of lead in a battery. when it is used electrons
move from 1 type to the other. when it is charged they move
the other way
