History and introduction of lead acid batteries
In 1951, German archaeologists found tools from the Parthian period (250 BCE to 224 CE) near Ctesiphon. After examination, it was found that these tools are electric cells that were made and used by Iranians. He published this found in an article, describing the device
The Role of Lug Preheating, Melt Pool Temperature
Abstract : This work deals with effective parameters in the cast-on-strap (COS) process during which gridlugs of a lead-acid battery are joined together by a strap. The effects of lug preheating, melt pool temperature, and lug entrance delay on the quality of joints and casting defects
Optimization of grid configuration by investigating its effect on positive
Abstract : With increasing the applications of lead-acid batteries, the demand for efficient, low resistant and inexpensive batteries has increased drastically. As discharge rates increase, ohmic voltage losses in current collecting system become more important. In this study, numerical methods are employed to investigate the
The effect of grid configurations on potential and current density distributions in positive plate of lead–acid battery via numerical modeling
Abstract : During the last decades, huge efforts have been made to enhance the efficiency as well as performanceof lead–acid batteries. The configuration of grid wires plays an important role in minimizing the ohmicdrop and hence, improving its current collecting ability. In the current study,
