Title

From Lithium-Ion to Sodium-Ion Batteries: Structural aspects

Date & Time: Thursday 7th February, 2019 at 4.00 PM

Venue: SSCU AUDITORIUM

Abstract:

Rechargeable batteries are the unavoidable objects in our modern life style. Their extensive applications in portable electronics lead the primary focus of R&D to Lithium-ion batteries (LIBs) within the past few decades. In recent years, new aspects like electric vehicles (EVs) and stationary grid storages are demanding for new materials with high power and energy densities. Though LIBs have many promising features, there are issues related to resource of lithium and other LIB components. If the EVs and grid storage reach the global market it will increase the materials demand and supply chain will be challenged. Sodium can be a better substitute for lithium which poses similar chemical properties. Today researchers motivated towards sodium ion batteries (SIBs) because of large abundancy and the hope to make a battery cheaper than LIBs.

In this talk, I will discuss the comparison of selected electrode materials when used in LIBs and SIBs. The comparison will mainly be focused on the structural behavior of intercalation materials during the charge/discharge cycles, advantages and challenges on conversion electrodes will be addressed.
