What is a secondary cell? Give examples of it.
(N/A) secondary cell is a type of electrochemical cell that can be recharged after use by passing an electric current through it in the opposite direction,allowing it to be used again.
$(i)$ $A$ good secondary cell can undergo a large number of discharging and charging cycles.
$(ii)$ The most important examples of secondary cells are the lead storage battery and the $Ni-Cd$ cell.
