⚡ What Is a Lithium Battery?

A lithium battery is a type of rechargeable battery that uses lithium ions to store and release energy. The most common type is the lithium-ion (Li-ion) battery, which moves lithium ions between the anode and cathode during charging and discharging.

Unlike traditional lead-acid batteries, lithium batteries are:

• Lighter

• More energy-dense

• Longer-lasting

• Faster-charging

🔬 How Do Lithium Batteries Work?

A lithium-ion battery consists of:

• Anode (usually graphite)

• Cathode (often lithium metal oxide)

• Electrolyte (allows ion movement)

• Separator (prevents short circuits)

When charging:

• Lithium ions move from the cathode to the anode.

When discharging:

• Lithium ions move back to the cathode, releasing energy to power devices.
