The exploration and use of renewable energy to generate electricity can effectively reduce societies’ reliance on fossil fuels and create a sustainable future for all. However, renewables are inherently intermittent, and therefore require advanced energy storage and conversion systems, such as rechargeable batteries, to provide a continuous power supply. Sodium-ion batteries (NIBs) are one such system that is particularly well-suited to large-scale energy storage applications, thanks to the abundance of the component resources. This significantly lowers the cost of NIBs.

In this talk, Dr. Jian Peng will present a rational design of low-cost Prussian blue analogs as cathode materials for sodium-ion batteries with low cost and high voltage, as well as enhanced energy density and extended cycle lifespan. The synthesis chemistry, structural engineering and electrochemical characterization techniques used in this research will be discussed in the context of their practical applications.
