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

Abstract

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.

Description

technical field [0001] The invention relates to the field of lead-acid batteries. Background technique [0002] At present, the colloidal electrolytes used in colloidal batteries can be roughly divided into silica sol-based and silica-based. The molecules in the colloids obtained by the existing preparation methods are independent and only physically mixed. The nature of the colloid is fully reflected. In recent years, small sealed lead-acid batteries have been widely used in electric vehicles due to their stable performance, low price, and maintenance-free advantages. However, with the increase of people's awareness of environmental protection and the formation of green barriers in various countries, environmental problems have become more and more prominent. How to meet people's needs and reduce environmental pollution as much as possible? Pollution in lead-acid batteries can be roughly divided into three major parts --- three wastes in the early stage of manufacturing,...

Problems solved by technology

Both the first and third blocks can be processed centrally, but the second block is quite scattered and difficult to handle! The use of colloidal electrolyte can greatly prolong the service life of the battery and avoid the discharge of acid mist, but the traditional colloidal electrolyte has a short gel time and poor permeability, and the silicon element contained in it will increase the internal resistance of the battery and reduce the charge and discharge performance. drop, loss increases
