Appeared in 1996, Lithium Ferro Phosphate technology, also LiFePO4, is taking place of other technologies because of its technical advantages. This technology is applied to traction applications, but also to energy storage applications such as self-efficiency, Off-Grid or UPS systems.

There are many common types of lithium ion batteries (with more being invented every day, it seems), lithium iron phosphate batteries have been existing for 2 decades or so (invented in 1996). This particular battery chemistry gains great popularity in automotive applications, because it's durable, stable, and well-suited to starting vehicles. Deep-cycle lithium iron phosphate batteries also strike a good balance between energy storage and life-span...they can be depended upon for years of use.

Lithium Iron Phosphate Battery Pros And Cons

Lithium Iron Phosphate Battery Advantages    

Long life span is 5-10 years while lead acid is 1-3 years, depending on depth of discharge and assuming that the cycle limit doesn't kill the battery first

Longer cycle life, as rechargeable LiFePO4 battery pack lasts 1,000 to 3,000 charge and discharge cycles, compared to similarly sized lead-acid batteries, which can lasts 200 - 1000 cycles (again, assuming depth of discharge is within recommended limits for both battery types).

LiFePO4 batteries are less affected by to  depth of discharge. A LiFePO4 battery can be dropped to 20% of charge without long-term damage. Most lead-acid batteries lose capacity or cycle life if they're discharged more than 50%.

Lighter than lead-acid batteries.

Arguably, rechargeable LiFePO4 battery pack is more environmentally friendly than lead acid.

Very safe - the odds of a "thermal runaway" (aka battery fire) are very low. The same can not be said of other lithium ion chemistries.

Lithium Iron Phosphate Battery Cells Disdvantages

As mentioned, LiFePO4 batteries are costly.

Lithium iron phosphate battery cells are hard to find offline. Most must be purchased online.

Possibily damaged because of overcharging (it's very important to use a charging system that's designed for LiFePO4 batteries if you don't want to shorten their life).

As stated in the introduction, there are  more lithium iron phosphate battery advantages than other batteries in just about every measurable way. But they're more costly, with a 100ah or 125ah Group 31 size LiFePO4 battery running between $1,000 on the low end and $3,000+ on the high end (as of August, 2015).
