An Optimized Preparation Procedure of Tetrabasic Lead Sulfate for Lead-Acid Batteries

“…39 The raw materials of the high temperature sintering process are lead oxide and sulfuric acid or lead sulfate and the product has complete crystal shape, suitable particle size, high purity and high energy consumption. 35 The ball mill method use high purity lead or lead oxide and sulfuric acid as raw materials and the product has incomplete crystal shape, low purity, but suitable particle size. 25 The product obtained by hydrothermal synthesis with lead oxide and sulfuric acid as raw materials has complete crystal shape, suitable particle size, and high purity and meets the market requirements.…”
