LiFePO4 batteries are a type of lithium battery built from lithium iron phosphate. Other batteries in the lithium category include:

Lithium Cobalt Oxide (LiCoO22)
Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2)
Lithium Titanate (LTO)
Lithium Manganese Oxide (LiMn2O4)
Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2)
You might remember some of these elements from chemistry class. That’s where you spent hours memorizing the periodic table (or, staring at it on the teacher’s wall). That’s where you performed experiments (or, stared at your crush while pretending to pay attention to the experiments).

Of course, every now and then a student adores experiments and ends up becoming a chemist. And it was chemists who discovered the best lithium combinations for batteries. Long story short, that’s how the LiFePO4 battery was born. (In 1996, by the University of Texas, to be exact). LiFePO4 is now known as the safest, most stable and most reliable lithium battery.
