Lithium-Ion – NMC vs LFP
Did you know that lithium-ion is actually a collective name with several different chemistries underneath its umbrella? Two well-known chemistries are Nickel Manganese Cobalt (NMC) and Lithium Ferro Phosphate (LFP). But what differentiates the two chemistries apart?
Lithium Nickel Manganese Cobalt Oxides – LiNixMnyCozO₂ – batteries are commonly found in electric cars, power tools and mobile electronics such as mobile smartphones and laptops. What NMC holds to its benefit is that it has a good specific power density and specific energy.
- NMC holds a very high energy density (∼250Wh per kg, LFP has ∼160Wh per kg).
- It unfortunately has many risk factors in terms of its safety.
Lithium Ferro Phosphate – LiFePO₄ – batteries are commonly used for home energy storage, vehicles, and solar-powered lighting systems. As LFP is made with lithium-ion derived chemistry it holds many advantages and disadvantages with other lithium-ion versions. There are however some significant differences.
- It doesn’t contain cobalt or nickel, two components that hold human rights and environmental concerns.
- The price of LFP is significantly lower than the price of NMC.
- Other than having a lower initial cost than NMC, LFP offers a longer cycle life than other lithium-ion chemistries. Compared with the 1000-2300 cycles of NMC, a LFP battery can deliver more than 10 000 cycles under optimal conditions.
- LFP batteries are a great alternative to lead acid batteries.
- A big and very important advantage is the safety of LFP batteries. This thanks to its thermal and chemical stability.
We see that the trend for the coming 5 years is the growing of about 10% of LFP batteries due to the rapid rise of the electrical automotive sector and the energy storage applications.
