Abstract

The invention discloses a preparation method of an electrolyte of a lead acid storage battery. The preparation method has the advantages that the technology is simple; the preparation method is suitable for being applied; the cost is lower; the water retention ability is stronger, and the fluidity regulating property is good; the loss of the electrolyte moisture in the use process of the battery is effectively reduced; the cycle life of the lead acid storage battery is prolonged; the electrolyte is in a gel state in the finished battery under the normal condition, does not flow, and is easy toform a three-dimensional porous structure, the gas synthesizing is easy, and the loss of water is reduced; the gel electrolyte in the diluted sol state is injected into the battery, and can fill thewhole pole plate space of the battery, so that the reaction of each part of the pole plate in the battery is uniform.

Description

technical field [0001] The invention relates to the field of battery materials, in particular to a method for preparing an electrolyte for a lead-acid storage battery. Background technique [0002] Storage battery was invented by Plante in 1859 and has a history of more than 100 years. Since the invention of lead-acid batteries, they have always had an absolute advantage in chemical power sources. This is because of its low price, easy access to raw materials, sufficient reliability in use, suitable for large current discharge and wide ambient temperature range. Lead-acid batteries are currently the most productive and widely used secondary batteries in chemical power sources. However, when lead-acid batteries are connected to the circuit and discharged, electrons are released from the anode (negative plate), and the formed Pb2+ ions immediately react with SO42- ions. Insoluble sulfates are deposited on the electrode surface. [0003] As an energy storage unit, the valve-...
