Strategies for the development of high-performance electrode materials for sustainable Li-, Na-, and K-ion batteries

Batteries have become essential in tackling global warming and energy security. Rechargeable Li-ion technology, by having the highest energy density of any such device, is considered as the battery of choice for electric vehicles and large-scale smart grids. However, lithium ion batteries cannot stand alone to fulfill future needs; therefore, it is urgent to develop new energy storage devices with high safety, lower cost, high energy density and green sustainable to realize mobiles and large-scale applications. Due to the high abundance of sodium and potassium, Na-ion batteries and K-ion batteries have recently emerged as highly promising candidates. In this seminar, we present one-step preparation of composite materials using spray-drying or hydrothermal synthesis routes, two techniques which offer easy scaling-up of production. The objective of this presentation is to demonstrate that the addition of the carbon sources/allotropes during the material preparation allows to control the particle morphology and ensures intimate mixture of the active material and conductive carbon that enhance the electrochemical performance of the electrode materials for Li-, Na- and K-ion batteries [1-6].
