LITHIUM IRON PHOSPHATE VS. LITHIUM-ION: DIFFERENCES AND ADVANTAGES

Lithium-ion and Lithium iron phosphate are two types of batteries used in today's portable electronics. While they both share some similarities, there are major differences in high-energy density, long life cycles, and safety. Most people are familiar with lithium-ion as they most likely own a smartphone, tablet, or PC. Lithium iron phosphate is a newer type of battery gaining recognition in the manufacturing industries due to its cost-effective materials and stability with high temperatures.

Life Cycle Differences

Lithium iron phosphate has a lifecycle of 1,000-10,000 cycles. These batteries can handle high temperatures with minimal degradation. They have a long life for applications that have embedded systems or need to run for long lengths of time before needing to be charged.

Life Cycle Differences: ( Bigger and Heavy )

For lithium-ion, the higher energy density makes it more unstable, especially when dealing with higher operating temperature environments. It has a life cycle of 500-1,000 cycles as it can be negatively impacted based on the operating temperature of the electronics or working components.

Safety Advantages Of Lithium Iron Phosphate: ( Bigger and Heavy )

Manufacturers across industries turn to lithium iron phosphate for applications where safety is a factor. Lithium iron phosphate has excellent thermal and chemical stability. This battery stays cool in higher temperatures. It is also incombustible when it is mishandled during rapid charges and discharges or when there are short circuit issues. Lithium iron phosphate does not normally experience thermal runaway, as the phosphate cathode will not burn or explode during overcharging or overheating as the battery remains cool.

However, the chemistry of lithium-ion does not have the same safety advantages as lithium iron phosphate. Its high energy density has the disadvantage of causing the battery to be unstable. It heats up faster during charging as a lithium-ion battery can experience thermal runaway.
