At its core, a battery is an energy storage device that converts chemical energy into electrical energy. It consists of two electrodes – a positive electrode (cathode) and a negative electrode (anode) – immersed in an electrolyte solution. The electrodes are made of different materials, each with its own unique properties.
Lithium-ion battery (LIB) is one of rechargeable battery types in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and back when charging. It is the most popular choice for consumer electronics applications mainly due to high-energy density, longer cycle and shelf life, and no memory effect.

A cathode and an anode are the two electrodes found in a battery or an electrochemical cell, which facilitate the flow of electric charge. The cathode is the positive electrode, where reduction (gain of electrons) occurs, while the …
You need a positive electrode, you need a negative electrode, and — importantly — you need an electrolyte that works with both electrodes. An electrolyte is the battery component that transfers ions — charge-carrying particles — back and forth between the battery''s two electrodes, causing the battery to charge and discharge.
