A method for evaluating the performance for positive electrod grids of lead/acid batteries
Abstract
For a battery plate to function satisfactorily,there must be a good contact at the interface between the grid and active material.This is because the adhesion of active material changes due to the state of interface between the grid and the active material.In this study the adhesion of active material is studied by the evaluation of grid surface.A grid with good adhesion has following characteristics(i)change in the rest potential is fast(ii)the lead sulphate membrane formed on the surface is thin and(iii)the change in potential during oxidation is slow.Good or bad adhesion of the active material can be judged using an evaluation method using the criteria.The annealing method of grid is evaluated using this method.
