Electrolyte for lead-acid storage battery, and preparation method and application of electrolyte

The invention discloses an electrolyte for a lead-acid storage battery, and a preparation method and an application of the electrolyte. The electrolyte comprises the following components in parts by weight: 30-60 parts of sodium carboxymethylcellulose, 20-35 parts of polyacrylamide, 15-30 parts of fumed silica, 10-20 parts of sulfuric acid, 8-15 parts of catalyst, 5-10 parts of aqueous ammonia, 3-8 parts of boric acid, 4-6 parts of ethylene diamine tetraacetic acid, 2-4 parts of sodium sulfate, 2-4 parts of stannous sulfate, 2-4 pars of potassium sulfate and a proper amount of solvent. When the electrolyte for the lead-acid storage battery is applied to the battery, the discharge attenuation of the battery can be slowed down, thereby prolonging the service life of the lead-acid storage battery. 本发明公开了种铅酸蓄电池电解液及其配制方法和应用，该电解液包括如下重量份的各组分：羧甲基纤维素钠30-60份、聚丙烯酰胺20-35份、气相二氧化硅15-30份、硫酸10-20份、催化剂8-15份、氨水5-10份、硼酸3-8份、乙二胺四乙酸二钠4-6份、硫酸钠2-4份、硫酸亚锡2-4份、硫酸钾2-4份及适量溶剂。该铅酸蓄电池电解液应用于电池中，能够延缓电池的放电衰减，从而延长铅酸蓄电池的使用寿命。
