Different Types of Batteries Available
Batteries are made up of more than one voltaic cell and aim to convert the chemical energy into high value voltage or current. In general, the batteries are classified into two broad categories, primary batteries and secondary batteries. Primary batteries can’t be recharged, once the initial chemical reactants in them are completely used up. On the other hand, the secondary batteries can be recharged by reversing the chemical reaction and restoring the original amount of the chemical reactants.
Primary batteries are also known as disposable batteries and they are most commonly used for portable devices with low current requirements. Some of the examples of primary batteries include zinc-carbon batteries, alkaline batteries, aluminum batteries, dry cells, lithium batteries and so on. Secondary batteries are mainly used as car batteries and in the devices like mobile phones and laptops. Lead-acid battery is the most common type of secondary batteries, though there are many more available in the form of lithium ion battery, nickel-zinc battery, polymer based battery, nickel-cadmium battery and so on.
Batteries can also be classified on the basis of wet or dry reactants included in their designs. The batteries containing liquid reactants or electrolyte are called wet cell batteries, while those containing electrolyte in the form of a dry paste are called dry cell batteries. On the basis of applications, batteries can be classified in the categories like atomic battery, backup battery, car battery, nano battery, tractions battery and watch battery. Learning about each of them can help you purchase the right battery.
