Sodium-ion Battery

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.

Features:

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.

Energy density

Na-ion cells have energy densities similar to those of conventional Li-ion materials

Power

Initial electrochemical tests have shown that the rate capabilities of Na-ion materials can be as good as those of conventional Li-ion materials

Safety

Safer materials (improved thermal stability) and improved transport safety

Cycle life

Preliminary cell testing has shown excellent cycle life

Shelf life

Preliminary analysis indicates similar shelf life to currently available Li-ion materials

Intellectual property

Compared to Li-ion technology, relatively little research has been conducted on Na-ion materials..
