Lithium-Ion Batteries: Powering the Modern World

From smartphones and laptops to electric vehicles and renewable energy storage, lithium-ion (Li-ion) batteries have become the backbone of today’s portable and sustainable energy solutions. Known for their efficiency, high energy density, and rechargeability, these batteries have revolutionized the way we use and store power.

What is a Lithium-Ion Battery?

A lithium-ion battery is a type of rechargeable battery that uses lithium ions as the primary charge carrier. During charging and discharging, lithium ions move between the positive electrode (cathode) and the negative electrode (anode) through an electrolyte, enabling energy storage and release.
