Na-ion cells offers an efficient alternative to lithium-ion phosphate (LFP) as the latter has disadvantage over lithium and other battery raw material prices.
The three main Na-ion cathode type that uses low-cost materials than Li-ion cathodes.
Prussian white
layered oxide
polyanion
Therefore, Na-ion is expected to be at least 20% cheaper than LFP
Na-ion has lower energy density and insufficient charge-discharge cycles compared to Li-ion ones, but is much safer and perform better in a wide operational temperature range.
However, greater cell and pack material costs could result in Na-ion being more costly.
Itis a type of rechargeable battery and it replaces lithium with sodium as the cathode material.
The largest advantage of sodium-ion batteries is the natural abundance of sodium which can be readily harvested from saltwater.
