Can a gel electrolyte be used in valve-regulated lead-acid batteries?
Therefore the novel gel electrolyte, a blend of colloidal and fumed silica, has great potential for application in the gelled electrolyte valve-regulated lead-acid batteries.
Can fumed and colloidal silica be used to prepare a gel electrolyte?
In this paper, fumed and colloidal silica were combined to prepare a novel mixed gel electrolyte for overcoming the disadvantages of gel electrolytes prepared with fumed or colloidal silica, thereby improving the physical and electrochemical properties and optimizing the overall performance of the gel electrolyte. 2. Experimental 2.1.
Do gelling agents participate in electrochemical reactions in lead acid batteries?
The gelling agents do not participate in the electrochemical reactions within lead acid batteries; their main function is to form a three-dimensional network structure, entrapping the sulfuric acid solution.
What happens if gelling agents are mixed with lead sulfate?
It is also found that, when gelling agents are mixed, the formation of lead sulfate from the lead is increased, implying that the activity of negative discharge reaction is improved and the capability of lead-acid battery is upraised, which is generally consistent with capacity testing below. Fig. 8.
What are the advantages of gel electrolytes containing colloidal silica?
The gel electrolytes containing colloidal silica have advantages of simple preparation, storage and gel perfusion, and low cost.
