Difference for lithium battery and LiFePO4 batteries:
1. Chemical Composition and Positive Electrode Material
Lithium-ion Batteries: Lithium-ion batteries can use various materials for their positive electrode (cathode), including cobalt, nickel, manganese, or combinations thereof (such as in NMC or NCA batteries).
LiFePO4 Batteries: LiFePO4 batteries specifically use lithium iron phosphate as the positive electrode material.
2. Safety and Stability
Lithium-ion Batteries: While lithium-ion batteries offer high energy density, some types, particularly those with cobalt-based cathodes, may have safety concerns due to the potential for thermal runaway and explosion under certain conditions, such as overcharging or physical damage.
LiFePO4 Batteries: LiFePO4 batteries are generally considered safer due to their thermal stability. They have a lower risk of thermal runaway and are less likely to explode under extreme conditions.
3. Energy Density
Lithium-ion Batteries: Lithium-ion batteries, particularly those with nickel- or cobalt-based cathodes, can offer higher energy densities compared to LiFePO4 batteries. This makes them suitable for applications where high energy output and compact size are critical, such as in some mobile devices and electric vehicles.
LiFePO4 Batteries: LiFePO4 batteries typically have lower energy densities. While this may not be a drawback in all applications, it means that they may require larger physical size or more batteries to achieve the same energy storage capacity as some lithium-ion batteries.
