Abstract: Post-lithium-ion batteries for sustainable energy storage

Batteries are considered to be one of the key solutions to integrate renewable energy resources to energy storage system. Due to the high energy density of lithium-ion batteries, they are widely used in portable electronic devices and utility-scale energy storage systems. Due to the limited availability of lithium, rechargeable batteries based on abundant elements (sodium, potassium, aluminium, magnesium, and iron) are gaining interest as potential alternatives to lithium-ion batteries. Practically, post lithium-ion batteries exhibit low charge storage performance and durability. This in turn depends on the electrode materials and electrolytes used in the batteries. In this talk, the existing limitations of sodium-sulfur, iron and aluminium-ion batteries along with plausible solutions will be covered.  Specifically, the structural modification of electrode material for aluminium-ion and sodium-sulfur batteries in enhancing the storage performance and durability will be discussed. Also, the selective choice of electrode and electrolyte for the feasible reversibility of  iron-ion batteries will be discussed.
