DOE ExplainsBatteries. 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
Altogether these changes create an expected 56% improvement in Tesla''s cost per kWh. Polymers are the materials of choice for electrochemical energy storage devices because of their relatively low dielectric loss, high voltage endurance, gradual failure mechanism, lightweight, and ease of processability.
