Lead–Acid Batteries
Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies …
Effect of silica soot on behaviour of negative electrode in lead–acid batteries …
1. IntroductionThe electrolyte of valve-regulated lead–acid (VRLA) batteries with gelled-electrolyte is a type of thixotropic colloid in a ''soft solid'' state. It is prepared by mixing silicon gel or silica soot with sulfuric acid, in which the silicic acid condenses and forms a ...
