Storage Cell Batteries
Storage batteries produce electricity from chemical action somewhat similar to the primary cells. However, the process can be also reversed by applying an external source of electricity in a charging process. This is normally done with a battery charger, or with an alternator such as in a car or truck. During recharging, some but not all of the electrons are moved back on to their original electrode. Each time the battery is recharged, fewer electrons are moved back to their original electrode and eventually, the battery can no longer be recharged.
There are several common types of storage batteries which include:
- lead-acid batteries, which are used in cars, trucks, and boats,
- alkaline batteries,
- nickel-cadmium batteries,
- lithium and others.
The nickel-cadmium battery is commonly used in tools where the rechargeable feature is desired. There is also significant ongoing storage cell research to support electric vehicle development, since battery performance is critical to these vehicles.
