Recent efforts towards developing novel lead electrodes involving carbon and composites have shown potential for increasing the cycle life of lead–acid (LA) batteries used to store energy in various applications. In this study, first-principles calculations are examine structural stability, defect formation energy, migration barrier C Pb LA batteries. Density functional theory with GGA-PBE perf...

Estimating the state of charge is important for any battery operated device. In case of automobile batteries, which are designed to deliver large power, many methods such as open circuit voltage based, ampere hour counting based, impedance based are used for calculating the state of charge. Internal resistance of a battery at a particular temperature directly gives the information about the sta...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...

With the increase in battery usage and decommissioning of waste power batteries (WPBs), WPB treatment has become increasingly important. However, there is little knowledge systems norms regarding performance dismantling treatments, although such facilities factories are being built across globe. In this paper, environmental investigated quantitively using life cycle assessment (LCA) methodology...

A new valve regulated lead-acid (VRLA) gel motive power battery and PV system power center have been tested in the laboratory and at a PV hybrid telecommunication site. The power center provides battery charge control, system remote communications, and data acquisition at the field test site. Extensive laboratory and field-test data were used to improve battery performance by optimizing, regula...

OBJECTIVE To evaluate lead exposure among lead-acid battery workers in Korea, to evaluate in more detail the erythrocyte pyrimidine 5'-nucleotidase (P5N) test for lead exposure, and to evaluate the abnormal accumulation of erythrocyte pyrimidine nucleotides in the battery workers. METHODS Activity of P5N and other biological variables were examined in 66 exposed workers in a lead-acid battery...
