How do batteries store electricity?

Batteries and similar devices accept, store, and release electricity on demand. They 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.

What is the main method batteries use to store energy?

Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. They accept, store, and release electricity on demand.

How do batteries function?

Batteries work by converting electricity into a chemical potential form before it can be readily stored. They consist of two electrical terminals, the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit.

Why is battery storage important?

Battery storage is critical to integrating renewable energy sources into our electricity supply. It is also key to reducing our dependency on petroleum for transportation by enabling the widespread use of plug-in electric vehicles.

What are scientists studying about batteries?

Scientists are using new tools to better understand the electrical and chemical processes in batteries to produce a new generation of highly efficient, electrical energy storage. Batteries were invented in 1800, but their complex chemical processes are still being studied.

What are scientists improving in batteries?

Scientists are developing improved materials for the anodes, cathodes, and electrolytes in batteries to better understand the electrical and chemical processes in batteries and produce a new generation of highly efficient, electrical energy storage.
