Overview of Lead acid battery

Lead Acid Battery The lead acid battery is the oldest type of rechargeable battery, and was invented in 1859 by French physicist Gaston Plante. In these batteries electrical energy can be stored as chemical energy and this chemical energy is then converted into electrical energy as and when required. The conversion of chemical energy into electric energy by supplying of external load is known as discharging of batteries, whereas the conversion of electrical energy into chemical energy by external electrical source is known as charging of battery. Lead acid batteries are made out of a Lead-dioxide cathode, a spongy metallic lead anode and a sulfuric acid solution electrolyte. The substantial metal component makes them poisonous and discreditable transfer can be dangerous to nature. The hypothetical voltage of these batteries is 12 V for 6 cages and 2 V for one cage.

Advantages of lead acid battery:

  • Low cost
  • Reduced internal impedance
  • Indefinite shelf life when stored in the absence of electrolyte
  • Available in wide range of sizes and capacities
  • The world's most recycled product
  • Little or No maintenance

Shortcomings of lead acid battery:

  • Heavy and bulky
  • Risk of overheating while charging
  • Not recommended for fast charging

Certain study done on lead acid battery market states that charging a lead acid battery is simple, yet the right voltage limits must be watched. Picking a low voltage limit covers the battery; however, this produces poor execution and causes a development of sulfation on the negative plate. A high voltage limit enhances execution but forms grid corrosion on the positive plate, while sulfation can be turned around if serviced in time, although corrosion is permanent. A lead acid battery comprises of a negative electrode made of spongy or permeable lead. The lead is permeable to facilitate the arrangement and disintegration of lead. The positive electrode comprises of lead oxide. Both electrodes are submerged in an electrolytic solution of sulfuric acid and water.
