**Other Considerations**
- **Environmental Friendliness**: Choose a battery type that is friendly to the environment, such as sodium ion or lithium iron phosphate.
- **Charging Speed**: If fast charging is required, select a battery that supports high rate charging (e.g., lithium-ion battery).
- **Size and Weight**: For portable devices, choose a lightweight, small-sized battery.
- **Brand and Quality**: Choose a reputable brand to ensure the reliability and safety of the battery.
**Practical Examples**
- **Electric Vehicles**: Priority is given to lithium-ion batteries (e.g. Li-ion ternary batteries or lithium iron phosphate batteries) due to their high energy density and long cycle life.
- **Home Energy Storage**: choose lithium iron phosphate or sodium ion batteries for their high safety and low cost.
- **Drones**: choose lithium polymer batteries for their high energy density and strong discharge capability.
- **Backup Power Supply**: choose lead-acid batteries or lithium iron phosphate batteries for their low cost and high reliability.
