Lithium battery

A lithium battery is a type of rechargeable battery that uses lithium-based materials to store and release electrical energy.

Common Types

• Lithium-ion (Li-ion): Used in phones, laptops, power banks, electric vehicles, etc.
• Lithium iron phosphate (LiFePO₄ / LFP): Safer and longer-lasting; common in solar storage and some EVs.
• Lithium-polymer (Li-Po): Lightweight and flexible; common in drones and portable electronics.

Advantages

• High energy density
• Lightweight
• Rechargeable
• Low self-discharge
• Long cycle life, depending on chemistry

Important Safety Point

Lithium batteries can overheat, catch fire, or become damaged if overcharged, punctured, short-circuited, or exposed to excessive heat. Use the correct charger and avoid using swollen or physically damaged batteries.

If you tell me what you want to know—working principle, types, charging, battery life, safety, or lithium batteries for solar/EVs—I can explain it simply.
