Rare-earth containing collidal electrolyte solution for accumulator and its preparing method

Abstract

This invention discloses a colloid electrolyte containing rare earth used in the battery and its preparation method relating to a lead acid battery electrolyte and its method which includes sulfuric acid 34%-37%, sodium silicate 2%-3.5% counted in terms of SiO2, cerous ammonium nitrate 0.05-0.1%, Fe<0.004%. It's difficult for the said electrolyte to become the lean solution since its surface is 10%-15% higher than that of ordinary absorption sulfuric acid electrolyte, the actual capacity is increased, the constant current discharge time is prolonged, its density is high and temperature variance of charge / discharge is small, not easy to form 'heat out-off-control' harm the pole plates.

Description

Technical field

[0001] The invention relates to a lead-acid accumulator electrolyte and a preparation method thereof, in particular to a colloidal electrolyte for an accumulator and a preparation method thereof. Background technique

[0002] In recent years, colloidal electrolytes for batteries have developed rapidly. Usually, this kind of electrolyte is mainly prepared with sulfuric acid and silicic acid solution as the main raw materials. Reaching about 80% of the capacity of the sulfuric acid electrolyte, there are disadvantages such as low output and poor high-current power generation capacity. Contents of the invention

[0003] The purpose of the present invention is to provide a technical solution for a new type of electrolyte that increases the initial capacity, and another purpose of the present invention is to provide a preparation method for the electrolyte.

[0004] The present invention is realized through the following technical proposals. The electrolytic so...
