Abstract

The invention belongs to the technical field of storage batteries, and particularly relates to an additive for a lead-acid storage battery gelled electrolyte and a preparation method and application thereof. In the prior art, the lead-acid storage battery has low stability, high resistance and short cycle life, and the additive raw material for the lead-acid storage battery gelled electrolyte is harmful to body health and ecological environment. The additive for the lead-acid storage battery gelled electrolyte is prepared from the following raw materials: 1-butyl-3-methyl imidazole dodecyl sulfate, 1-allyl-3-methylimidazolium chloride, nano boron oxide, titanium dioxide, nano titanium diboride, graphene, acetylene black, sulfate, lubricating grease, polyacrylamide, sulfuric acid solution,and distilled water. The additive for the lead-acid storage battery can effectively lower the battery internal resistance, enables the battery to better carry high current, increases the capacity andprolongs the cycle life of the lead-acid storage battery, thereby being worth promoting.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to an additive for colloidal electrolyte of lead-acid storage batteries, a preparation method and application thereof. Background technique [0002] In storage batteries, lead-acid batteries have the advantages of mature technology, cheap price, good charging and discharging performance, and safe use. As the most important stable power supply and DC power supply, they are widely used in aviation, railways, automobiles, ships, communications, and finance In various industries such as military and national defense, it has become an indispensable energy product in social production and human life. Lead-acid battery refers to a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of t...
