Abstract

The invention discloses a preparation method for lead acid battery electrolyte, wherein the electrolyte activator comprises: deionized water, nickel sulfate, cobalt sulfate, aluminum sulfate, sodium sulfate, lithium iodide and lithium carbonate, and the electrolyte ingredients are prepared as follows: 5-10 parts by weight of a stabilizing agent, 6-13 parts by weight of colloidal silica, 5-12 parts by weight of analytically pure sulfuric acid, 20-30 parts by weight of pure water, and 2-5 parts by weight of the electrolyte activator. By using the electrolyte prepared by the method, the internal resistance of the lead acid battery can be reduced, and the capacity and the service life of the lead acid battery can be improved.

Description

Technical field [0001] The present invention involves a preparation method of electrolyte, especially the preparation method of a lead -acid battery electrolyte. Background technique [0002] With its excellent performance price ratio, lead -acid batteries occupy a pivotal position in the field of secondary batteries. Among all the aqueous solution power system, lead -acid batteries have high working voltage, good large current discharge performance and high and low temperature dischargePerformance, it is suitable for both floating charges, but also for starting and recycling.Therefore, lead -acid batteries are widely used in spare power supply, energy reserve, power and energy.The electrolyte of the lead -acid battery is generally mixed with sodium silicate and sulfate solution, but the internal resistance of this electrolyte is large and the capacity is reduced. Invention content [0003] The purpose of the present invention is to provide a preparation method of an electrolyte...
