Product Description

What is SIB/NIB/sodium ion battery?

A sodium-ion battery (NIB or SIB) is a rechargeable battery that uses sodium ions (Na+) as a charge carrier. In some cases, its working principle and battery structure are similar to the lithium-ion battery (LIB) type, but it uses sodium instead of lithium as the cathode material. Sodium and lithium belong to the same group in the periodic table of elements and therefore have similar chemical properties. .

Will sodium batteries replace lithium batteries?

Sodium-ion batteries may not replace all lithium-ion batteries on the market, but will be used in certain applications that don't necessarily require high energy density, such as large-scale power grids or smaller modes of transportation. Sodium-ion batteries will be used in certain applications that don't necessarily require high energy density, such as large-scale power grids or smaller modes of transportation.

Temperature test

How do sodium-ion batteries work?

Sodium-ion batteries consist of a cathode based on a sodium-containing material, an anode (not necessarily a sodium-based material), and a liquid electrolyte containing a dissociated sodium salt in a polar protic or aprotic solvent. During charging, sodium ions are extracted from the cathode and inserted into the anode, while electrons travel through an external circuit. During discharge, the reverse process occurs and sodium ions are extracted from the anode. and reinserting the cathode, the electrons do useful work through the external circuit.
