Lithium-ion batteries are in almost every gadget you own. From smartphones to electric cars, these batteries have changed the world. Yet, lithium-ion batteries have a sizable list of drawbacks that makes lithium iron phosphate (LiFePO4) a better choice.
How Are LiFePO4 Batteries Different?
Strictly speaking, LiFePO4 batteries are also lithium-ion batteries. There are several different variations in lithium battery chemistries, and LiFePO4 batteries use lithium iron phosphate as the cathode material (the negative side) and a graphite carbon electrode as the anode (the positive side).
LiFePO4 batteries have the lowest energy density of current lithium-ion battery types, so they aren’t desirable for space-constrained devices like smartphones. However, this energy density tradeoff comes with a few neat advantages.
The Advantages of LiFePO4 Batteries
One of the main disadvantages of common lithium-ion batteries is that they start wearing out after a few hundred charge cycles. This is why your phone loses its maximum capacity after two or three years.
LiFePO4 batteries typically offer…
