More broadly, storage can provide electricity in response to changes or drops in electricity, provide electricity frequency and voltage regulation, and defer or avoid the need for costly investments in transmission and distribution to reduce congestion.
There are three primary energy storage systems: batteries, electrochemical capacitors, and capacitors. An electrochemical capacitor (EC) otherwise known as a supercapacitor is an energy storage device that fill the gap between dielectric capacitors and batteries.
To accept and release energy, a battery is coupled to an external circuit. Electrons move through the circuit, while simultaneously ions (atoms or molecules with an electric charge) move through the electrolyte. In a rechargeable battery, electrons and ions can move either direction through the circuit and electrolyte.
