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.
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.
A corrosion layer forms between the electroplated lead layer and the positive active material, creating a continuous conductive structure between the titanium substrate and the active material. As a result, the combination between the titanium substrate grid and the battery active material is guaranteed.
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.
Simulated power battery testing at 0.5 C discharge rate to 100 % DoD shows that the cycle life of the lead acid battery using the titanium-based positive grid reaches 185 cycles, which is twice higher than the comparison electrode's 60 cycles and significantly better than other lightweight grids [30, , , ] (see Table 2).
