Problems solved by technology

[0002] Lead-acid batteries widely used in automobiles, ships, generators, and various construction machinery generally use dilute sulfuric acid as the electrolyte. Traditional lead-acid batteries have poor charge and discharge performance, low temperature performance, and charge-free performance during use. Neither is ideal; at the same time, it is easy to be affected by dumping, vibratio

Abstract

The invention discloses a silicon dioxide paste electrolyte, which comprises: 50~55wt% sulfuric acid with 1.45 specific weight, 32~38wt% pure water, 10~12wt% gas-phase silicon dioxide, 0.008~0.015wt% ammonium polyacrylate, and 0.2~0.4wt% phosphoric acid. Wherein, the preparation method comprises: (1) dissolving part gas-phase silicon dioxide into sulfuric acid to form A constituent; (2) dispersing other silicon dioxide into water to form B constituent; (3) dissolving the ammonium polyacrylate into pure water by proportion 1:100 to form C constituent; (4) mixing A, B and C constituents; adding proper phosphoric acid when using. The opposite accumulator with this electrolyte has well property, and can replace current lead-acid accumulator.

Description

technical field [0001] The invention relates to an electrolyte, in particular to a silicon dioxide paste electrolyte used in accumulators, and also relates to a processing method for the electrolyte and an accumulator using the electrolyte. Background technique [0002] Lead-acid batteries widely used in automobiles, ships, generators, and various construction machinery generally use dilute sulfuric acid as the electrolyte. Traditional lead-acid batteries have poor charge and discharge performance, low temperature performance, and charge-free performance during use. None of them are ideal; at the same time, it is easy to be affected by dumping, vibration, and turbulence during use, resulting in liquid leakage and acid mist, which will cause great damage to instruments, equipment, vehicles, ships, etc. that use batteries, and even worse, the environment and personal cause a great impact. Although the traditional lead-acid battery has the above-mentioned series of deficiencie...
