The future of the way we make, transmit, and use power rests heavily on the shoulders of energy storage technology.
The technology used in these days is LITHIUM-ION which will be replaced by SODIUM-ION.
Sodium-ion batteries (SIB) are a type of rechargeable metal-ion battery that uses sodium ions as charge carriers.
Sodium is abundant, operates at a slightly lower potential which would make them practical for grid storage. Sodium makes up the Stanford battery’s cathode, and the anode is made from phosphorus, with the addition of a compound called myo-inositol, which can be derived from rice bran or corn.
1.Na ion has exceeding energy densities than Li ion.
2.Na-ion material can be processed in the same way as Li-ion materials at every step, from the synthesis of the active materials to the electrode processing.
3.This will allow current Li-ion battery manufacturers to use existing equipment to construct batteries.
4.Existing Li-ion manufacturing lines can be used to make Na-ion batteries.Current collectors in sodium-ion cells can be fabricated from aluminium rather than the more expensive copper necessary in lithium cells.
Na-ion cells have energy densities similar to those of conventional Li-ion materials
Initial electrochemical tests have shown that the rate capabilities of Na-ion materials can be as good as those of conventional Li-ion materials
Safer materials (improved thermal stability) and improved transport safety
Preliminary cell testing has shown excellent cycle life
Preliminary analysis indicates similar shelf life to currently available Li-ion materials
Compared to Li-ion technology, relatively little research has been conducted on Na-ion materials..
