Fuel cells are electrochemical devices that convert chemical energy directly to electricity, with water and heat as the only byproducts. They have great potential for both stationary and transportation applications and are expected to help address the energy and environmental problems that have become prevalent in our society. Despite their great promise, they have not been widely adopted mainly due to lower than predicted efficiencies, high cost, and short lifetime. With the commercialization of Toyota’s fuel cell vehicle Mirai in 2015, the development of fuel cells has been accelerated, especially in China. This talk will firstly introduce some fuel cell basics, and then discuss their applications, recent progresses and market analysis.

Wearable energy storage devices are indispensable corner stones for future wearable electronics. Current energy storage technologies are based on materials and devices that are rigid, bulky, and heavy, making them difficult to wear. On the other hand, textiles are flexible and lightweight materials that can be assembled into different textiles and have been worn by human beings thousands of years. Different from conventional two-dimensional thin films and foils, the three-dimensional fibre and textile structures not only provide superior wearing ability, but also much larger surface areas. This talk will introduce how our research group makes use of the attributes of textiles for high-performance wearable energy storage devices. We will demonstrate the strategies and discuss the perspectives to modify fibers and textiles for making wearable capacitators and batteries with excellent mechanical durability, electrochemical stability, and high energy/power density.

He is elected as Founding Member of The Hong Kong Young Academy of Sciences.
Energy storage system is the crucial component for the development of renewable energy, smart city and green transportation. However, conventional Li-ion batteries have potential risks of fire explosion, which limits their wide applications in large-scale and populated residential buildings and urban cities. This presentation discusses recent development of aqueous batteries including redox flow batteries (RFBs) and high-voltage aqueous Li-ion batteries. Redox flow batteries offer unique advantages of high efficiency, low cost, scalability and rapid response for grid energy storage. We will discuss strategies to improve the energy density of aqueous RFBs. Developing low-cost and eco-friendly aqueous electrolytes with a wide voltage window is critical to achieve safe, high-energy and sustainable Li-ion batteries. We will discuss a new aqueous electrolyte using the water-miscible polymer poly(ethylene glycol) as the crowding agent to decrease water activity, thereby achieving a wide electrolyte operation window (3.2 V) with low salt concentration (2 m). This new electrolyte design provides a path for designing high-voltage aqueous electrolytes for low-cost and sustainable energy storage.
