What is a battery?
Quick Answer
A battery is a device that stores chemical energy and converts it into electrical energy. It works through redox reactions between electrodes and an electrolyte.
The Full Story
A battery produces electricity from chemical reactions that involve electron transfer between materials. In a typical cell, oxidation happens at one electrode and reduction at the other, with ions moving through the electrolyte. Modern batteries range from disposable alkaline cells to lithium-ion batteries used in phones and electric vehicles. The development of the rechargeable battery has been crucial for portable technology.
