Quanhong YangTianjing University, China
Quanhong Yang is a full professor of applied chemistry and materials science of Tianjin University (TJU). He is also a "Pengcheng Scholar”Professor (short-term) of Graduate School at Shenzhen, Tsinghua University. He was born on February 1972, graduated from Tianjin University of China in 1994 with a bachelor’s degree in polymer engineering and obtained his Ph.D. on carbon materials from ICC CAS in 1999. Then, he continued his carbon research as postdoctoral fellows and research fellows in IMR CAS, CNRS France, Tohoku University and Southampton University. Since September 2006, he joined Tianjin University (TJU) as full professor.
His research is totally related to novel carbon materials, from porous carbons, tubular carbons to sheet-like graphenes with their applications in energy storage (lithium ion battery and supercapacitor) and environmental protection. His research contributes to over 100 peer-reviewed papers published on Adv Mater, JACS, Sci Rep, Nano Lett, ACS Nano, Energy Enviorn Sci, Adv Energy Mater, Adv Funct Mater, etc. He was awarded some academic awards including Nature Science Award of Tianjin (1st class, 2013), the Science and Technology Progress Award of Tianjin (1st class, 2012) and the Brian Kelly Award (2004). Now he holds over 20 patents about graphene and nanocarbons.
He serves as the member of the editorial boards of seven journals: Carbon (Elsevier), Materials Research Express(IOP), Transactions of Tianjin University, Journal of Tianjin University, New Carbon Materials, Carbon Technology and Plating & Finishing.

Abstract
Electron and ion transport are critical issues for high performance Li-based batteries. Carbon components are always introduced into the electrode system to promote the electron and ion transport and optimize the electrolyte-active materials interface. As a basic unit and building block of diverse carbon forms, graphene offers us opportunities to design and control these carbon components and their nanoarchitectures.[1] In this talk, we present our contributions on graphene-based structures for various Li-based batteries, including multidimensional carbon-based conductivity network for Li-ion batteries,[2, 3, 4] hierarchical ion transport channels for Li-ion and Li-S batteries,[5,6] carbon coating for the interfacial electrochemical reaction suppression of Li4Ti5O12 electrode,[7, 8] carbon buffers for volume control of metal or oxides,[9] carbon surface-assisted adsorption of S species for high performance Li-S battery[10] and all-carbon catalysts for Li-O2 battery.[11]
