Advantages of a Lithium Iron Phosphate Battery

The lithium iron phosphate battery, sometimes also referred to as LFP battery, is an advanced type of lithium ion battery having lithium iron phosphate as its cathode material and a beryllium anodized graphite anode as its anode. Compared to other lithium ion batteries, this type has a higher capacity per cell for some applications such as in high-power automotive and marine applications. LFPs can also be used in hand-held and mounted applications in the same applications as other types of lithium batteries. They are often preferred over other types due to their extended shelf life, superior power density, better power cycling capabilities, and energy densities that are similar to those of graphite or lithium polymer.

There are many advantages and disadvantages of the lithium iron phosphate (LFP) batteries. It is important to note that while these advantages and disadvantages have been identified, they are only a rough estimate as current battery technologies continue to improve. While some of the possible disadvantages do not pan out as being real concerns, others could be addressed with future technology. These potential downgrades of this new power source are discussed below. Note that these are not all inclusive and that additional factors, such as cost, could also affect your decision to purchase one.

Disadvantages of LFPs: As with all lithium-ion batteries, there is a chemistry issue involving the trivalent iron phosphate or GP. This chemical structure creates a reaction between the trivalent iron phosphate and the alkaline base material creating an undesirable reaction that causes degradation in performance. This reaction does not happen consistently though. There is some improvement in performance when using a standard lithium battery, but it is still a concern.

Cost: The cost to produce a single cell LFP is about half of what it costs to produce a similar sized battery in standard chemistry. This cost savings can add up quickly. Because of this, a single lithium-iron battery can last much longer than standard chemistry. For this reason, many batteries are designed for extended shelf life. A battery that can last up to six years on the shelf is very useful.

Advantages of LFP: One of the major advantages of LFP is that it has a much higher density than standard lithium-based batteries. This allows it to take up more space and allows for greater weight. It also weighs less, which is important for applications that require a smaller, lighter, battery. In addition, since it is made up of three different materials, LFPs have better electrochemical properties that make them more stable under adverse conditions. This makes it useful for use in weather related applications as well.

The combination of superior energy density, long shelf life, and durability make LFPs the ideal choice for high power, high voltage, short run times, and mobile application. Many applications where high power, long run times, and portability are important are served by the combination of lithium iron phosphate and lithium ion batteries. Although they cost more initially, LFPs pay for themselves over time as they save money on purchase, replacement, and maintenance costs. There are numerous advantages to using lithium iron phosphate or LPI batteries.
