Problems solved by technology

The coagulation time of the colloidal electrolyte is less than or equal to 45 minutes when the battery is poured. The time is too fast, and the pouring is difficult, and it cannot be mechanized and industrialized. The acid ion cannot penetrate the battery, so the acid content of the battery plate is insufficient, and the battery capacity is small and the service life is short. , high cost of preparation

Abstract

The invention relates to an electrolyte preparation method of three-dimensional nanometer silicon liquid storage batteries. The electrolyte consists of double ingredients: an ingredient A and an ingredient B, and contains silicon, sulphuric acid, phosphoric acid, lithium, potassium, aluminum, polyethylene glycol and purified water. The invention can realize the effects of high power, small internal resistance, long service life, at least five years of the colloid stability period, little self discharge and two years of storage period after sufficient charging of a colloid storage battery. The power maintains 90 percent, the self charging recovery reaches 90 percent, the invention is applicable to military combat readiness and automobile manufacture and storage, and the environment protection and energy saving effect reaches 30 percent. The maintenance is avoided, and the use is safe and reliable.

Description

technical field [0001] The invention relates to a storage battery, and further refers to a method for preparing the electrolyte of a three-dimensional nano-silicon liquid storage battery. Background technique [0002] At present, the electrolyte used for colloidal batteries at home and abroad is a silicon solution prepared from fumed silica. It is commonly known as "fired" silica gel solution. Another special nano-silicon solution imported from Japan for colloidal batteries is the electrolyte prepared by SNOWTEX-20. The coagulation time of the colloidal electrolyte is less than or equal to 45 minutes when the battery is poured. The time is too fast, and the pouring is difficult, and it cannot be mechanized and industrialized. The acid ion cannot penetrate the battery, so the acid content of the battery plate is insufficient, and the battery capacity is small and the service life is short. , the preparation cost is high. The power characteristics of the three-dimensional na...
