Lithium iron phosphate batteries and lithium-ion batteries are currently relatively advanced secondary battery technologies. Compared with traditional lead-acid batteries, nickel-metal hydride batteries, etc., they have higher energy conversion efficiency, lower self-discharge rate, longer service life and other advantages, and the impact on the environment is relatively small.
Do you know what type of battery is the power supply you bought? Which battery type is more suitable for my use? Here I made a table comparing the advantages and disadvantages of lithium iron phosphate batteries and lithium-ion batteries.
COMPARISON LiFePO4 Battery & Lithium-ion Battery
|
Item |
Lithium iron phosphate battery (LiFePO4) |

Lithium iron phosphate battery has longer cycle life |
|
Safety |
High (no thermal runaway) |
Low (risk of explosion or fire) |
Lithium iron phosphate battery is safer |
|
Cost |
Low (cheaper materials) |
High (more expensive materials) |
Lithium iron phosphate battery is cheaper |
|
Temperature performance |
Good (Stable at high temperatures) |
Good at low temperatures |
Both have their strengths |
In general, Lithium iron phosphate batteries and lithium-ion batteries have their own advantages and disadvantages. Which one is better depends on your use and needs.
If you need to consider factors such as safety, durability and cost when choosing an outdoor power supply, then a lithium iron phosphate battery may be more suitable for you.
If you need to consider factors such as energy density, charge-discharge efficiency and low temperature resistance, then a lithium-ion battery may be more suitable for you.
