During the past several years extremely corrosion-resistant positive grid materials have been developed for lead acid batteries. These alloys consist of a low calcium content, moderate tin content, and additions of silver. Despite the high corrosion resistance these materials present problems in battery manufacturing.
Lead-acid batteries, specifically flooded types, can be corroded. However, timely maintenance can help delay it. In contrast, AGM, gel, dry cell, and lithium batteries, whether ion or iron phosphate, don't have external corrosion issues. Battery corrosion is dangerous.
To prevent corrosion on flooded lead-acid batteries, avoid overcharging and undercharging. Proper maintenance, such as using grease on the terminals, and storing the battery with a sufficient charge are also important. For alkaline batteries, remove them from devices when not in use.
Lead acid batteries have a high weight to volume ratio. Their hazards include: corrosive contents, and the risk of short circuit - accidental discharge. Current flow by external short circuit may heat metals to welding temperatures with a fire hazard. Internal heat generated may boil battery acid with the evolution of large amounts of highly corrosive acid mist/vapor.
When lead oxides are used for the paste formulation, the free lead may be corroded preferentially to the grids. For lead antimony and most calcium alloys the grids are corroded preferentially to the free lead giving a good bond between grid and active material even if substantial free lead remains in the cured plate.
For the first time positive grids are more corrosion resistant under curing conditions than the free lead in the past mixture. Despite the calcium content of these alloys, the tin and silver content as well as segregation of these alloying elements during solidification reduce the rate of attack of the paste.
