Secondary Cells
This type of cells can be recharged by passing direct current through them and can be used again and again. Some examples are lead-storage battery, nickel, cadmium storage cell, etc. let us study the working of lead storage cell.
Lead storage battery: it is the most frequently used battery in automobiles. It consists of six voltaic cells connected in series. In each cell anode is made of spongy lead and cathode is a grid of lead packed with lead dioxide (pBO2). The electrolyte is the aqueous solution of H2SO4 which is 38% by mass. The reactions taking place this type can be represented as:

During the working of the cell, the concentration of H2SO4, decreases as sulphate ions are consumed to from PbSO4. The PbSO4 precipitates and partially gets coated on both the electrodes and water formed dilutes the sulphuric acid. With the decrease in the concentration of H2SO4 the density of the solution also decreases. The condition of the battery can be easily checked by measuring the density of the solution.
To enhance the output of the cell, the anode and cathode plates are arranged in alternating manner and they are separated by sheets insulating material. The anode and cathode plates are separately connected to each other so as to increase the electrode area in contact with electrolyte solution. This increases current delivering capacity of the cell. The cells are further connected in series so as to increase the voltage of the battery. In 6 volts battery there are 3 cells and in 12 volts battery there are 6 cells.
Recharging the battery: the battery can be recharge by connecting it to an eternal source of direct current with voltage greater than 12 V. it forces to electrons to flow in opposite directions resulting in the deposition of Pb on the anode and PbO2 on the anode and PbO2 on the cathode.
During the recharging operation the cell behaves as electrolytic cell. The recharging reactions are:
