High-molecular nano polymer electrolyte for lead-acid battery and its compounding method

The electrolyte of macromolecule nanometer polymer used in lead acid storage battery and its preparation method were related in this invention. It relates the area of lead acid storage battery. According the weight ratio, the electrolyte is mainly made up of the raw materials as following: ligand agent 0.1-1.5%, complexing agent 2.5-4%, catalytic agent 0.01-0.5%, stabilizing agent 2.3-3.8%, conditioning agent 0.1- 0.5%, antifoam agent 0.01-0.5%, sulfuric acid 36-45%, the others is water. It is characterized in that the content of silicon dioxide is low, the dosage is little and the cost is also low. And in that a steady colloid can be formed in the electrolyte which can elongate the gelatum time. Used in the minitype encapsulation lead acid storage battery, the capacity can increase greatly, the operational life can be elongated and the low temperature resistance can also be enhanced. The gel in the electrolyte can avoid the overflow of acid liquor. Otherwise, the electrolyte also has the merits of little inherent resistance, high capacity, longevity and good thixotropy and so on.
