Lithium-ion batteries have the following advantages.

Lithium-ion batteries have the following advantages.

1. High energy density: depending on the electrode material, it can reach 150～200Wh/kg (540～720kJ/kg) by mass; it can reach 250～530Wh/L (0.9～1.9kJ/cm3 by volume) ). 

2. High open circuit voltage: It varies with electrode materials, up to 3.3~4.2V.

3. Large output power: varies with electrode materials, up to 300～1500W/kg (@20sec). [1][Does not match the source]

4. No memory effect: Lithium iron phosphate lithium ion battery has no memory effect. The battery can be charged and discharged at any time without being discharged, and it is easy to use and maintain.

5. Low self-discharge: <5%～10%/month. Due to the built-in monitoring circuit of the smart lithium ion battery, the working current of this monitoring circuit is even higher than the self-discharge current.

6. Wide operating temperature range: it can work normally between -20℃～60℃.
7. Fast charging and discharging speed

所以, lithium-ion batteries are widely used in consumer electronics, military products, and aviation products.
