What are the problems encountered in lead acid batteries?
Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.
Do lead acid batteries lose water?
The production and escape of hydrogen and oxygen gas from a battery causes water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
What are the advantages of lead acid batteries?
One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.
What is a lead acid battery?
The lead acid battery is traditionally the most commonly used battery for storing energy. It is already described extensively in Chapter 6 via the examples therein and briefly repeated here. A lead acid battery has current collectors consisting of lead. The anode consists only of this, whereas the anode needs to have a layer of lead oxide, PbO 2.
What happens when a lead acid battery is fully discharged?
In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge. The dependence of the battery on the battery state of charge is shown in the figure below.
Are lead acid batteries corrosive?
However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coulombic efficiencies of 85% and energy efficiencies in the order of 70%.
