A lithium-ion battery (Li-ion battery) is a type of rechargeable battery that uses lithium ions as the main component for energy storage. It is widely used in numerous electronic devices, ranging from portable electronics to electric vehicles.
Here are some key features and characteristics of lithium-ion batteries:
- High Energy Density: Lithium-ion batteries have a high energy density, which means they can store a large amount of energy in a relatively small and lightweight package. This makes them suitable for portable devices where space and weight are important considerations.
- Rechargeable: Lithium-ion batteries are rechargeable, allowing them to be used repeatedly. They can be charged and discharged multiple times without significantly degrading their performance.
- Voltage Stability: Li-ion batteries provide a stable voltage output throughout most of their discharge cycle, which ensures consistent power delivery to electronic devices. This is advantageous for devices that require a steady power supply.
- Low Self-Discharge: Lithium-ion batteries have a low self-discharge rate, meaning they retain their charge for extended periods when not in use. This allows devices to remain powered even after being idle for some time.
