Lithium-Ion Battery: An Overview
Lithium-ion (Li-ion) batteries are one of the most widely used energy storage technologies in modern electronics, powering everything from smartphones and laptops to electric vehicles and renewable energy systems. Known for their high energy density, lightweight structure, and long cycle life, Li-ion batteries have become the preferred choice for both consumer applications and industrial systems.
How Lithium-Ion Batteries Work
A lithium-ion battery operates through the movement of lithium ions between the anode and cathode via an electrolyte. During charging, lithium ions move from the cathode to the anode and are stored. When the battery discharges, the ions travel back to the cathode, generating an electric current. This reversible process allows multiple charging and discharging cycles.
