In a conventional lead-acid battery, the grid plate is cast from an alloy of lead and up to 5-12% antimony. (Some manufacturers use arsenic.) Adding the antimony to the lead (to be sure, when a substances, mostly metal, is added to another metal, an alloy is formed) strengthens the soft lead, improves adhesion of active mass and protects the lead against

Lead-antimony alloys have been used in lead-acid batteries for many years because they improve the battery''s performance by increasing its efficiency and reducing its self-discharge rate. However, lead-antimony alloys have some drawbacks, such as reduced cycle life and increased water loss. This is where lead-calcium batteries come in. Calcium
Strength is required in lead battery alloys for two distinct reasons. Sufficient grid stiffness is required for efficient processing of grids through automatic pasting machines and other
By 2000, most lead-acid, starting/lightening/ignition (SLI) batteries produced in the Western world had made the transition from traditional lead-antimony alloy grids to lead-calcium-based alloys. The automobile requirements for high cranking performance and maintenance-free batteries have accelerated the trend. Cost reductions as well as high numbers of grids-per-battery have led to
KeywordsPb–Sb alloy-Battery grid-Distortion-Embrittlement-Segregation-Dendrites-Cellular structure. Low-antimony lead alloys have been successfully produced by a unique continuous casting
Lead–antimony alloys have a low melting point, are easily cast into the required shapes, and have high mechanical properties to permit easy processing into finished batteries. The antimony also modifies the surface of the positive grid to permit excellent recharge of the battery after discharge. Antimony, however, is transferred to the
Lead antimony alloy is largely used for grids production of lead-acid battery. Antimony improves the cast ability and the subsequent handling of the grid alloy. In addition, this alloy is extremely strong and creep-resistant and can be cast into rigid, dimensionally stable grids that are capable of resisting the stresses of charge/discharge
In this paper, we present accelerated test data which show the superior anodic corrosion and growth behavior of pure lead as compared to lead calcium and lead-antimony positive grids for lead-acid batteries in float service. We relate differences in growth behavior to differences in metallurgy for these three alloy systems. Pure lead has been incorporated into circular grid

Lead-antimony alloys having above 2.5% antimony are not adequate for high capacity, maintenance-free battery grid alloys; rather, the antimony content must be further reduced to reduce water loss or gassing batteries during charging and increase the conductivity of the grid alloy, thus increasing the cold cranking performance of the battery.
Lead–tin alloys are used as grid materials and strap alloys for VRLA batteries where the negative effects of antimony on battery performance are most severe. The high tin content of lead-, calcium-, tin-, and silver-based alloys reduces the rate of corrosion at elevated temperatures .
The material composition and grid structure of lead-acid battery plates are crucial factors influencing their performance in starting and energy storage applications. Both types of batteries utilize lead-based materials, but their specific formulations and grid designs are tailored to their intended uses. Antimony-lead alloys are commonly

At present, about 70–80% of the world''s output of lead is consumed by battery industry. Since pure lead (Pb) is very soft and ductile, and has difficulty supporting its own weight, it is normally alloyed to increase the strength. Among many lead-based alloys, binary lead–antimony (Pb–Sb) alloys containing about 1–12 wt.% Sb have been
Lead– antimony alloys containing 9–12% antimony are generally utilized to cast long-spined grids for tubular stationary or traction batteries. These alloys have either a single freezing point or a very small freezing range. The structures consist of 85–100% eutectic surrounding small lead islands as seen in Figure 1.The single freezing point allows the liquid metal to flow long

using lead antimony alloys are in the 4-6% range.)8 Identifying the Problem The use of lead antimony alloys spurred the growth of the battery industry and contributed to the improvements in manufacturing and the reduction of costs. But even with these benefits, there was a growing awareness by 1930 of some issues involving lead antimony alloys.
Lead Antimony Antimony was the first impurity introduced into the manufacturing process of lead acid cells around 100 years ago. For the most part, throughout the first half of the 20th century, manufacturers refined their processes with the use of antimony alloys in the range of 9-12%.
During the past 10 years, lead calcium based alloys have replaced lead antimony alloys as the materials of choice for positive grids of both automobile and stationary
For example, maintenance-free batteries have triggered the replacement of lead–antimony alloys by lead–calcium–tin alternatives for both negative and positive grids. In 2000, battery production in Europe showed that lead–calcium–tin alloys accounted for 76 and 47% of the alloys used for negative grids and positive grids, respectively.
The Manchester plate is a hybrid design. While typically marketed as a pure lead design the grid is normally either a lead-antimony or lead-calcium alloy. The grid alloy results in a Manchex

The choice of grid alloy compositions used in a battery directly impacts the grid and product design, the plate manufacturing and assembly process, as well as long term product performance and reliability of the The use of lead antimony alloys spurred the growth of the battery industry and contributed to the improvements in
The two most common alloys used today to harden the grid are antimony and calcium. Batteries with these types of grids are sometimes called "lead-antimony" and "lead-calcium" batteries. Tin is added to lead-calcium grids to improve cyclability. The major differences between batteries with lead-antimony and lead-calcium grids are as follows:
Antimony was first identified and used as a lead alloy as far back as 1881, and it was immediately recognized that lead antimony alloys brought significant benefits to the performance and strength of lead plates used in battery production.
Over time antimony concentrations under 2% became the standard for stationary lead acid batteries in Europe. Key to this approach was the use of selenium in the alloy compositions, which acted as a stabilizer for the antimony, and led to a more hardened lead with a finer, denser grain structure.
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.
In reality, this battery is actually a low lead-antimony grid with a slight amount of selenium. Lead-selenium has characteristics that fall somewhere between lead-calcium and lead-antimony. When pure lead is mixed with an alloy there may be undesirable characteristics introduced in the performance of the battery.
Lead antimony alloys corrode more rapidly than lead–calcium alloys. Antimony is released during the corrosion process and, during recharge, is transferred to the negative plate where it causes unacceptable loss of water, particularly in high heat environments.
