Lead acid batteries are a type of rechargeable battery that primarily compete with lithium-ion and nickel-metal hydride batteries. They are known for their lower energy density, relatively high cost, and shorter lifespan compared to advanced battery technologies, yet they have advantages in cost, reliability, and recyclability.
The electrolyte in lead acid batteries serves as a medium that facilitates the movement of ions, allowing for the battery to generate electrical energy. It is crucial for the chemical reactions that occur during charging and discharging. The main roles of the electrolyte in lead acid batteries include:
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts.
