What is a supercapacitor?

A supercapacitor is a high-capacity capacitor with larger capacitance but lower voltage limits compared to batteries.

Describe the role of flywheels in energy storage.

Flywheels store energy in the form of kinetic energy by spinning a rotor in a vacuum environment at high speeds.

How does a flow battery differ from a typical battery?

Flow batteries store energy in liquid electrolytes that circulate through the system, allowing for separation of power and energy storage capacity.

What are the benefits of solid-state batteries?

Solid-state batteries use solid electrolytes, offering greater safety, higher energy density, and longer life compared to liquid electrolytes.

Define the term 'energy density.'

Energy density is the amount of energy stored in a given system or region of space per unit volume.
