Lead-acid batteries have been a longstanding choice for various aviation applications due to their robustness, proven reliability, and cost-effectiveness. This article explores the role of lead-acid batteries in aircraft systems, their advantages, limitations, and the future outlook for this technology in aviation. 1.
Numerous types of batteries have been developed and variants of some of them are used in aviation applications. These include: Lead Acid. A lead acid battery cell contains an anode made from lead oxide and a cathode of elemental lead immersed in an electrolyte solution of sulfuric acid.
One of the primary uses of lead-acid batteries in aviation is to provide the initial power needed to start aircraft engines. These batteries are designed to deliver a high surge current, which is necessary for the ignition of turbine engines and other aircraft systems. 1.2. Backup Power
Most small private aircraft use leadacid batteries. Most commercial and corporate aircraft use nickel-cadmium (NiCd) batteries. However, other lead acid types of batteries are becoming available, such as the valve-regulated lead-acid (VRLA) batteries.
Figure 4: A cutaway of a six cell 12 V lead-acid battery. In traditional lead-acid batteries the plates are immersed in liquid electrolyte. This is termed a flooded lead-acid battery as the electrolyte is free to move about in the cells. Charging the battery converts the lead sulphate that is deposited during discharge back into sulphuric acid.
The active materials found in a lead-acid battery are: Lead Dioxide, P b O 2, which forms the positive plate. Pure lead, P b, which forms the negative plate. Aqueous sulphuric acid, H 2 S O 4 ( a q), which forms the electrolyte solution.
