Abstract :
The change in the acid concentration in the vertical direction in a lead/acid battery is monitored continuously during charge/discharge cycling by means of a holographic laser interferometry method. It is found that there is a difference in the acid distribution in the upper and lower parts of the electrolyte due to uneven reaction speeds and acid movement by natural convection. This causes an interesting re-emergence of an uneven distribution during the interval between charge and discharge.
