Soaking electrolyte concentration during

Generally, formation is carried out under constant-current conditions. The changes in temperature, electrolyte concentration, and cell voltage during plate soaking and formation are presented in Fig. 3.2 [2]. Chemical reactions commence between PbO, basic lead sulfates, and H2SO4 when the plates come into contact with the solution.
