CUHK Research: Changing the world

Green energy Powering a green and safe future Lu Yi-chun Professor of Mechanical and Automation Engineering For more than a century, scientists have been finding ways to move towards a fossil fuel-free society, harnessing renewable energy from the sun, wind, water and other sources. Technological advances on different fronts are ever fuelling the demand for cheaper, safer and more efficient methods to store energy. In the race for advanced battery technologies, CUHK materials scientist Professor Lu Yi- chun, committed to clean energy storage, is building a new aqueous lithium-ion battery that is absolutely safe and a flow battery that promises commercially-viable massive storage of energy.
