Abstract:In these seminar series, I will talk the development of advanced rechargeable batteries and electrochemical catalysis based on materials architecture design. Lithium-air battery is one of the most promising systems for meeting today’s stringent requirements as the power source for electric vehicles. Porous graphene with different pore size architectures were synthesized as cathode catalysts for lithium-air batteries. Porous graphene exhibited significantly higher discharge capacities than that of non-porous graphene. The Ru nanocrystal decorated porous graphene exhibited an excellent catalytic activity with a high reversible capacity, low charge/discharge over-potential, and long cycle life.

Sodium-ion batteries and potassium-ion batteries are being considered as a promising system for stationary energy storage and conversion, owing to natural abundance of sodium and potassium. Several electrode materials were synthesized as either cathode materials or anode materials for sodium-ion batteries, potassium-ion batteries and sodium-sulfur batteries5-7. Lithium-sulfur batteries and sodium-sulfur batteries will also be discussed.
