A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an …
How a battery works
The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device for.
Can the lightning be captured and used as power source?
$begingroup$ Another consideration that could be added is that the available power from lightning isn''t really all that much. The power source for lightning is only a tiny fraction of the wind energy that powers the storm - so it would make more sense to extract the power from the wind in the first place, or from the sunlight that ultimately powers the wind. …
DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
