Problems solved by technology

[0006] During the circulation process of the electrolyte provided by the above disclosed patents, the metal oxides of the positive and negative electrodes become different in hardness and softness as the electrolyte changes in temperature and pressure. This kind of situation is called plate delamination in the industry. Ultimately, the polar plate is hard and soft at the bottom, which leads to the premature end of battery life; and the stratification of the electrolyte and the difference in density between the upper and lower sides are one of the main reasons for the sharp decline in the capacity of lead-acid batteries at low temperatures

Abstract

The invention belongs to the technical field of lead-acid storage battery production, and particularly relates to an anti-layering gel electrolyte for a lead-acid storage battery and a manufacturing method thereof. The anti-layering gel electrolyte for the lead-acid storage battery is prepared by the steps of firstly preparing raw materials including 36 percent of sulfuric acid, 0.45 percent of fumed silica, 0.06 to 0.065 percent of lithium sulfate, 0.008 to 0.012 percent of methylcellulose, 0.001 to 0.0015 percent of polyaspartic acid amide sodium salt and the balance of deionized water. Thegel electrolyte provided by the invention can reduce the pole plate softening due to electrolyte layering due to season change; the generation of thick lead sulfate crystals can be inhibited; the poleplate sulfation rate is decelerated; good gel performance and thixotropy are realized; the disposable glue filling can be realized by using the existing industrial vacuum glue filling machine.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage battery production, and in particular relates to an anti-delamination colloidal electrolyte for a lead-acid storage battery and a manufacturing method thereof. Background technique [0002] Due to its reliability, wide applicability, good performance and low price, lead-acid batteries have always been the mainstream secondary battery products in China and even in the world. The main components of lead-acid batteries include: positive and negative plates, glass fiber separators, battery tanks, battery covers, electrolyte (dilute sulfuric acid), lead-out terminals, safety valves, etc. As the main component of the lead-acid battery, the electrolyte not only maintains the ion transfer in the battery, but also participates in the electrochemical reaction. Its performance has a direct impact on the electrochemical performance and cycle life of the lead-acid battery. [0003] CN1750312A disclo...
