Abstract. Hybrid supercapacitor-battery is one of the most attractive material candidates for high energy as well as high power density rechargeable lithium (Li) as well as sodium ion (Na) batteries. Mostly two types of hybrids are being actively studied for electric vehicles and storage of renewable energies.
A supercapacitor (also called an ultracapacitor or electrochemical capacitor) is a type of electrochemical energy storage device.
