A lithium-ion (Li-ion) battery is a rechargeable energy storage device widely used in consumer electronics, electric vehicles (EVs), renewable energy systems, and industrial applications. It provides high energy density, long cycle life, and efficient power delivery, making it the preferred choice for modern battery technology.

How Does a Lithium-Ion Battery Work?
Charging Phase – Lithium ions move from the positive electrode (cathode) to the negative electrode (anode) through an electrolyte.

Discharging Phase – When in use, lithium ions move back from the anode to the cathode, releasi
