SEALED VALVE-REGULATED LEAD-ACID VRLA ACCUMULATOR BATTERY

摘要

The invention relates to electrotechnical industry in particular to lead/acid accumulators and accumulator batteries manufacturing. A sealed valve-regulated lead-acid VRLA-battery comprises accumulators, current -forming elements being positive electrodes with dioxide lead (PbCb), positive mass, negative electrode with mossy lead (Pb) active mass separated by fiber-glass separators and gel-like electrolyte based on diluted sulfuric acid thickened by fine silicone oxide, electrode terminals are made from low lead-calcic-tin composition with bithmus and aluminum addition, barium sulfate (BaSO) is added to negative mass, a borosicate glass fiber is added to positive mass, the battery has at least one safety valve for excess gas withdrawal. The technical result is the increase of vibration resistance of electrodes and the whole battery.
