A scientific seminar on "Prospects of rechargeable Sodium-Ion batteries" was held at the Nanoresearch laboratory of Baku State University. Laboratory researcher Almara Rahimli reported on rechargeable sodium-ion batteries, their advantages over lithium-ion batteries, their parameters, similarities and differences, and the latest innovations in this field.

The speaker noted that the structure of sodium-ion batteries is similar to lithium-ion batteries widely used in various electronic devices, but sodium ions are used instead of lithium ions to store energy. The advantage of sodium-ion batteries over lithium-ion batteries is lower production costs due to the unlimited supply of sodium. They can also be made in similar sizes to lithium-ion batteries, unlike sodium-sulfur batteries. Materials used as anodes in sodium-ion batteries swell up to 400-500 percent of their original size when interacting with sodium, causing mechanical damage and loss of electrical contact. Recently, research has been conducted on the application of new types of graphite layers for the negative electrode of sodium-ion batteries, and the hope that these types of batteries will replace lithium-ion batteries is increasing.

At the end of the seminar, the speaker answered the questions of the participants.
