A study on the relationship between microstructure and electrochemical performance of the phosphate electrode materials for Li-, Na-, and K-ion batteries

One of the main challenges of energy storage devices is the development of cheap and eco-friendly battery systems with high safety and high energy density. Battery is the best choice to store electricity in the form of chemical energy when considering the flexibility and constitute the limiting components in shift from petrol powered to electric vehicles, while also the use of the more renewable energy on the grid. Since the nineties, lithium-ion batteries (LIBs) have become one of the dominant technologies, however, lithium ion batteries cannot stand alone to fulfill future needs. Due to the high abundance of sodium and potassium, Na-ion batteries and K-ion batteries have recently emerged as highly promising candidates.
Electrode materials present the key component for the development for the new generation of the rechargeable batteries. This seminar will focus on the design, synthesis and characterization of high capacity phosphate electrode materials for Alkali-ion batteries with special attention paid to the control of microstructure as a tool to optimize their electrochemical properties. The materials have been prepared using facile, inexpensive and suitable synthesis methods (hydrothermal and spray drying) for powders with high homogeneity, leading to excellent electrochemical properties (1-6).
