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.
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.
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.
In the works of Kirchev et al., a carbon honeycomb grid model for valve regulated lead-acid batteries is described, with absorptive glass-mat separators [52, 53]. This shape corresponds to some extent to our hexagonal model, being used there as negative electrode. ... Leaf and hexagonal grid designs for lead-acid battery. An EIS analysis ...
Research has shown that the amount of titanium needed for preparing lead acid batteries with the same capacity is only one-tenth that of lead-based grids . This reduction in material weight results in a higher energy density for the battery.
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.

Lead Acid Battery
The concept on which modern grid materials are based was introduced in 1881 when E. A. Fauré developed and introduced the first lead–acid battery plate, which incorporated the mechanical application of active mass material onto a cast grid of lead–antimony alloy. For the next 70 years, the lead–acid battery grids remained much the same as the original grids developed by E. A. …
