The principle of operation of a VRLA (Valve Regulated Lead-Acid) battery is based on the chemical reactions that occur during charging and discharging. These reactions involve the
The valve-regulated lead–acid (VRLA) battery is designed to operate by means of an internal oxygen cycle (or oxygen-recombination cycle), where oxygen is evolved during the latter stages of charging and during overcharging of the positive electrode.
The valve-regulated version of this battery system, the VRLA battery, is a development parallel to the sealed nickel/cadmium battery that appeared on the market shortly after World War II and largely replaced lead-acid batteries in portable applications at that time.
Valve regulated lead acid (VRLA) battery constitutes towards the largest part of the worldwide secondary battery market share. Indisputably, absorptive glass mat (AGM) is a key component in a VRLA battery that is often engineered utilizing the synergy that exists between fiber and structural parameters.
Oxygen-recombinant valve-regulated lead-acid (VRLA) batteries [1,2] use the same technology as flooded lead-acid batteries, but the acid electrolyte is immobilised by sealing the battery with a valve. This eliminates the need for addition of water and avoids electrolyte mix preventing stratification.
Lead–acid batteries are employed in a wide variety of different tasks, each with its own distinctive duty cycle. In internal-combustion engine vehicles, the battery provides a quick pulse of high-current for starting and a lower, sustained current for other purposes; the battery remains at a high state-of-charge for most of the time.
The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs.
