Biography

PhD (HKUST)

Short Description

Dr. Qiang Liu received his Bachelor of Engineering degree in Metallurgical Science and Engineering from Central South University in 2010 and obtained his Master of Engineering degree in Electrochemical Engineering from the same institute. In 2017, he earned his Ph. D degree in Chemical and Biomolecular Engineering from The Hong Kong University of Science and Technology (HKUST). After graduation, he continued his research in the Department of Mechanical Engineering (PolyU) as a Research Associate for about 1 year. Afterwards, he worked in DJI Innovation to develop high energy-density lithium-ion battery materials and power estimation algorithm for drone applications.

Dr. Liu’s research interests concentrate on the ultra-conformal functional polymer coating on energy-storage material using chemical vapor deposition (CVD) method. The CVD is a unique, green and versatile technique for various polymers in-situ coating on almost any substrate materials, independent of their morphology and chemo-physical properties. In his research, the coating morphology, performance enhancing effect, and the role(s) of polymer coating are highly interested, aiming at next-generation energy-storage applications (lithium-ion batteries, Li-S batteries, Li-based batteries, and etc.). His pioneering work on CVD polymer coating on LIB materials has been published on top peer-review journal of Nature Energy.
