MANUFACTURE OF LEAD ACID BATTERY

摘要

PURPOSE:To increase formation efficiency by applying in-container formation to a battery comprising a formed positive plate and an unformed plate. CONSTITUTION:A plate group comprising a formed positive plate and an unformed negative plate is inserted in a container and a specified amount of H2SO4 having given concentration is poured. When the battery is charged, O2 gas is evolved from the positive plate and PbSO4 is converted into Pb in the negative plate by reduction reaction to progress formation. Compared with in-container formation of a battery comprising an unformed positive plate whose formation is difficult and an unformed negative plate, the formation efficiency of this battery is increased and the manufacture of a lead. acid battery is made sure and easy.
