What is a battery and how does it work?

What is a Battery?\ What is a Battery? A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit.

What is a 'battery'?

Historically, the ‘term’ battery has always been used in order to refer to the combination of two or more electrochemical cells. However, the modern definition of the term ‘battery’ is believed to accommodate devices that only feature a single cell.

What devices use batteries?

Batteries can be found in electrical devices that require power to operate. Flashlights, mobile phones, and laptops are all electrical devices that use batteries. The capacity of a battery is measured in milliamp-hours (mAh) How does a battery work? Batteries work by converting chemical energy into electrical energy.

What is a battery in electricity & electrochemistry?

battery, in electricity and electrochemistry, any of a class of devices that convert chemical energy directly into electrical energy. Although the term battery, in strict usage, designates an assembly of two or more galvanic cells capable of such energy conversion, it is commonly applied to a single cell of this kind.

How do batteries power our lives?

Batteries power our lives by transforming energy from one type to another. Whether a traditional disposable battery (e.g., AA) or a rechargeable lithium-ion battery (used in cell phones, laptops, and cars), a battery stores chemical energy and releases electrical energy.

What is a battery made up of?

Usually a battery is made up of cells. The cell is what converts the chemical energy into electrical energy. A simple cell contains two different metals (electrodes) separated by a liquid or paste called an electrolyte. When the metals are connected by wires an electrical circuit is completed. One metal is more reactive than the other.
