What is a Battery?
A battery is a device that converts stored chemical energy into electrical energy through a series of chemical reactions. It consists of one or more electrochemical cells, which are equipped with a positive electrode (cathode) and a negative electrode (anode) separated by an electrolyte. Batteries are used to power a wide range of devices, from small electronics like smartphones and laptops to larger equipment such as vehicles and backup power systems.
Types of Batteries
There are several types of batteries available, each with its own unique chemistry and applications. Some common types include:
- Lithium-ion batteries
- Lead-acid batteries
- Nickel-metal hydride batteries
- Alkaline batteries
Examples of Battery Applications
Batteries are used in various everyday devices, including:
- Mobile phones
- Laptops
