that the cadmium content of nickel-cadmium batteries is much lower than that of lead-acid batteries. However, we must take into account the fact that there are a number of exceptions
Another benefit of lead-acid batteries is the high recovery rate of spent batteries, and over 95% of lead can be recycled during the process [4,5]. Nowadays lead-acid batteries are widely used in
It is called a “lead-acid” battery because the two primary components that allow the battery to charge and discharge electrical current are lead and acid (in most case, sulfuric acid). Lead-acid batteries were invented in 1859 by Gaston Plante̒, a French physicist.
It is important to note that lead-acid batteries do not produce an electrical charge. They are only capable of receiving a charge from another source and discharging it later. The battery uses chemical reactions between the lead and acid to both store and discharge electrical current. Batteries are divided into cells.
Lead-acid batteries are known for their affordability and reliability. Their components include: Positive Plate: Made of lead dioxide, this plate participates in the chemical reaction to store energy. Negative Plate: Composed of sponge lead, this plate engages in the reaction to release energy. Electrolyte: A mixture of sulfuric acid and water.
The three major contributors to Lead-acid battery chemistry are lead, lead dioxide, and sulfuric acid. Unfortunately pure lead is too soft to withstand the physical abuse; about 6% antimony is added to strengthen it.
Lead-acid batteries can only undergo a set number of discharge/recharge cycles before the chemistry is depleted. Once the chemistry is depleted, the cells fail and the battery must be replaced. Service and maintenance of the batteries is critical to the reliability and the battery life.
Lead-acid batteries do not lend themselves to fast charging and, with most types, a full charge takes 14 to16 hours. A Lead-acid battery must always be stored at full state-of-charge. Low charge causes sulfation, a condition that robs the battery of performance.
