There are there different types of cell chemistries used for manufacturing battery packs for electric vehicles. They are
LFP- Lithium Ferrous Phosphate
NMC- Lithium Nickel Manganese Cobalt Oxide
NCA- Lithium Nickel Cobalt Aluminum Oxide
All of them have their own benefits and drawbacks, but the LiFePo4 cell, which is an LFP cell (Lithium Ferrous Phosphate), is considered the ace cell chemistry for the battery pack of an electric vehicle. There are some major and strong reasons for considering them the ace.
COST-
Compared to the other two cells the LFP battery cells are less costly and affordable. Most of the manufacturers prefer LFP cells more than the NCM and NCA because of their affordability.
SAFETY-
This being the major concern for both the manufacturers and buyers, LFP batteries are considered to be the safest batteries for an electric vehicle. They can withstand climatic and road conditions better than the other two types. The LFP batteries are much less likely to burn or produce high flames during a car crash, bike crash, etc. The high resistance towards heat than NMC/NCA makes the cells different and safer from the rest two.
LONG LIFE CYCLES-
Unlike NMC/NCA the life cycles or the charge cycles for LFP batteries are more than the NMC/NCA. Even the most well-known Tesla NCA battery can only maintain 70% of its capacity after 3000 cycles, while the lithium iron phosphate (LFP) battery will remain 80% after 3000 cycles. The NMC lithium battery has a theoretical life of 2000 cycles, but its capacity quickly declines to retain 60% when it runs 1000 cycles.
NMC/NCA cells are mainly used for manufacturing the battery packs for 4-wheelers, due to the constraints like space consumption, charge time, etc. But on an overall picture LFP batteries are preferred by two-wheeler battery pack manufacturers because of the benefits mentioned above.
Here at Agasty we manufacture batteries for two, three, and four-wheelers with LFP cells, and our experts’ designs and skills made the battery packs compete with all the features of NMC/NCA cell battery packs.
