Conclusions The titanium substrate grid composed of Ti/SnO 2 -SbO x /Pb is used for the positive electrode current collector of the lead acid battery. It has a good bond with the positive active material due to a corrosion layer can form between the active material and the grid.
A demonstration was conducted on a titanium-based lightweight positive grid for lead-acid batteries. The surface of the titanium-based grid exhibits low reactivity towards oxygen evolution. Titanium based grid and positive active material are closely combined. The cycle life of the lead acid battery-based titanium grid reaches 185 times.
Lead-acid battery is a reversible battery used generally automotive industry. A lead-acid battery cell contains two electrodes with pasted active material, an electrolyte and a separator. Electrode transmits current with electrons whereas electrolyte transmits current with ions. A grid is a solid electrode called as a current collector.
The grid boasts noteworthy qualities such as being lightweight and corrosion-resistant, which confer enhanced energy density and cycle life to the lead acid batteries.
Secondly, the corrosion and softening of the positive grid remain major issues. During the charging process of the lead acid battery, the lead dioxide positive electrode is polarized to a higher potential, causing the lead alloy positive grid, as the main body, to oxidize to lead oxide.
Later, the 3D mathematical model of the 2 V lead-acid battery was simulated by considering the thermodynamic and kinetic effects of the battery under certain conditions in order to measure the effect of the obtained grid geometries on the performance of the battery. These results can provide us with information before installing the test setup.
