Lithium-iron-phosphate (LFP) batteries address the disadvantages of lithium-ion with a longer lifespan and better safety. Importantly, it can sustain an estimated 3000 to 5000 charge cycles before a significant degradation hit – about double the longevity of typical NMC and NCA lithium-ion batteries.
Sodium ion cells, produced at scale, could be 20% to 30% cheaper than lithium ferro/iron-phosphate (LFP), the dominant stationary storage battery technology, primarily thanks to abundant...
It can reversibly release two Na + per formula unit (i.e., 128 mAh/g) at an average potential of 3.9V, thus offering a material-level specific energy of ∼507 Wh/kg, comparable to ∼580Wh/kg for LiFePO 4 (LFP), which is widely used as a positive electrode in Li-ion batteries.
To this end, this paper presents a bottom-up assessment framework to evaluate the deep-decarbonization effectiveness of lithium-iron phosphate batteries (LFPs), sodium-ion batteries (SIBs), and vanadium redox batteries (VRBs) in PV applications.

Car brands often use terms such as ''lithium-ion'' and ''LFP'' in marketing material, but what do they mean? Importantly, what are the differences and which is best for your needs when considering the electric switch?
It is a large, high-voltage energy storage block that''s positioned underneath the vehicle, similar to a fuel tank.
Conventional EV battery packs are made up of a number of smaller module blocks, which contain cells within them (either pouch, prismatic or cylindrical shaped).
The cells are made up of a cathode (positive terminal), a separator with liquid electrolyte, and an anode (negative terminal).
Charged particles (ions) need to move from cathode to anode via the electrolyte when charging – and vice versa when discharging – in order for electrons to move around between cathode and anode current collectors.
Ultimately, the process of moving ions and electrons will charge and discharge a battery.
''Structural batteries'' are emerging, where cells are directly embedded within the vehicle chassis, eliminating the need for space- and weight-wasting modules in a pack enclosure.
The BYD Seal debuted the unique construction in Australia, which is said to enable the electric sedan to be more space efficient, sit lower for better aerodynamic efficiency, and improve body stiffness.
However, this design has been questioned by vehicle design engineer and advisor Sandy Munro, who told Reuters [↗] that structural batteries have "zero repairability" in the event of an accident.
The key advantage for NMC batteries is higher energy density up to around 250Wh/kg – which means it can provide longer driving range by packing more energy in the volume of each cell and be space-efficient.
However, due to this, its cells have lower thermal stability and tend to reach the thermal runaway point earlier – a dangerous chain heating reaction causing a difficult-to-extinguish fire.
NMC batteries also require expensive, supply-limited and environmentally unfriendly raw materials – including lithium, cobalt, nickel and manganese.
On the other hand, due to lithium-ion''s global prevalence, there are more facilities set up to repurpose and recycle these materials once they eventually reach their end-of-life.
NMC also has a shorter lifespan by only being able to handle an estimated 1000 to 2000 full recharging cycles (0 to 100 per cent counts) depending on the manufacturer. But, the capacity may already degrade by around 40 per cent after 1000 cycles, according to Poworks [↗].
Most car brands recommend an 80 per cent everyday charging limit on NMC packs to maintain good health.
However, NCA swaps the manganese with more sustainable aluminium and uses less cobalt in the cathode.
Therefore, it still shares similar advantages and disadvantages with NMC across driving range, charging, longevity and thermal safety.
But, NCA isn''t as commonly adopted by car brands – though not all manufacturers disclose the exact cathode used and instead just quote ''lithium-ion''.
Importantly, it can sustain an estimated 3000 to 5000 charge cycles before a significant degradation hit – about double the longevity of typical NMC and NCA lithium-ion batteries.
Deep full recharging to 100 per cent also doesn''t drastically impact the battery health, which is why there''s generally no recommended daily charging limit to allow always utilising the full driving range capabilities. Regular full charging is in fact encouraged to help calibrate the cells.
The better stability also means it''s less susceptible to generating thermal runaway in the event of a short circuit or severe crash; it''s safer to operate in extremely low and high temperature environments.
Therefore, it typically offers less driving range than the equivalently-sized lithium-ion pack.
The chemistry is also more sensitive to low temperatures, resulting in a higher chance of DC charging speed throttling during colder climates.
While it doesn''t contain any environmentally contentious cobalt, nickel and manganese, it still relies on the expensive lithium material.
Even though it has a smaller carbon footprint from the factory, the lack of said materials means it overall has less recyclable content than a typical lithium-ion battery – with the industry still working to improve extraction processes for LFP.
LFP is theoretically the best as it currently is the longest-lasting battery type, can be regularly charged to 100 per cent, has less thermal runaway risk, and is cheaper to produce to enable more affordable EVs.
Meanwhile, lithium-ion (with NMC and NCA cathodes) provides more driving range, faster charging performance, and contains more recyclable content with today''s facilities.
In many respects, it''s the old ''horses for courses'' argument, though the next few years will see significant improvements in EV batteries.
