Chemical Compositions

LiFePO4 batteries, also known as lithium iron phosphate, are composed of lithium, iron, and phosphate ions, which makes them relatively safer, lighter, and more stable than other conventional batteries. On the other hand, Lithium Ion batteries contain metallic lithium and composite cathode materials like cobalt, nickel, or manganese, making them highly energy-dense and efficient.

 
Safety

LiFePO4 batteries are often regarded as the safer of the two due to their chemistry, which is less prone to overheating or exploding. By contrast, while lithium-ion batteries are generally safe when used properly, they have been known to overheat and catch fire if they are damaged or improperly handled. Therefore, LiFePO4 batteries are often preferred in applications where safety is a major concern like solar power systems, electric vehicles, and industrial equipment.
