"Carbon" researcher yangquanhong: give lithium batteries a big slimming down

in March 2018, yangquanhong guided students in the laboratory to verify the experimental data

"sometimes scientific research is very simple and not as profound as people think. What scientists have to do is to find out the real academic problems in daily life and 'pierce the window paper' so as to open a window and see the further scenery."

in April, the crabapple on the campus was in full bloom. Yangquanhong, Professor of the school of chemical engineering of Tianjin University and winner of the National Science Fund for Distinguished Young Scholars, also welcomed the scientific research cause like flowers

recently, his three papers were successively published in advanced energy materials, a top journal in the energy field. As early as January this year, he also proposed the "sulfur template method" for the first time, which makes it possible for the lithium-ion battery to become smaller in the early stage of heating. This achievement was published in the journal Nature communication

"this is a small step." On April 12, yangquanhong was interviewed by science and technology. Talking about her research results, yangquanhong seems low-key and pragmatic. Behind the plain is the persistence and dedication of this "carbon" researcher for more than 20 years

Yang Quanhong's first impression is that she has devoted herself to the field of energy storage and many studies have been internationally recognized. The 45 year old professor's research interests are carbon nano materials and new battery materials. After graduating from the Department of Applied Chemistry of Tianjin University in 1994, yangquanhong entered the Shanxi Institute of coal chemistry, Chinese Academy of Sciences and completed the master's degree and doctoral degree. That is, during his postgraduate study, he began to come into contact with carbon materials and became obsessed with them

since then, from the Institute of metals of the Chinese Academy of Sciences, the French scientific research center, Tohoku University of Japan and the University of Southampton in the United Kingdom to his alma mater Tianjin University in 2006, he has never left the "carbon" that fascinated him, and has devoted almost all his energy and heat to the design of high-volume energy density energy storage devices and carbon electrode materials, A series of key technological breakthroughs have been made in the application of graphene compact energy storage. These achievements are expected to make electronic products such as computers and laptops lighter and thinner

in order to obtain energy storage devices with smaller volume and higher capacity, his team proposed the design principle of high volume energy density energy storage devices from five aspects: strategy, method, material, electrode and device. If you still don't know the operating procedures, you can call the company's service 0531 (8) at any time, which laid a foundation for the practical application of carbon nano materials, It has effectively promoted the practical process of new electrochemical energy storage devices based on carbon nano materials. These research results have been published in important international academic journals and have been recognized by the industry

take the "grounded" route and draw achievements on the posters

"basic research should be able to make useful achievements and tell interesting stories." This is what yangquanhong often says

as early as 2015, yangquanhong was invited to publish the popular science article "how dreams shine into reality" on the people, introducing the application prospect and industrialization road of graphene

in yangquanhong's opinion, scientific research is sometimes very simple, unlike everyone else's Weston? 705 antioxidants make the use of food packaging materials so safe. What scientists have to do is often to find real academic problems from daily life, "pierce the window paper", so as to open a window and see the further scenery

"grounding gas" is a major feature of Yang Quanhong's scientific research work. In the corridor of the team laboratory, there are display posters designed by yangquanhong, two of which are particularly vivid

in one of the pictures, corn and popcorn are developed around the needs of major engineering construction, transformation and upgrading of traditional manufacturing industry, digital economy, bioeconomy, new energy vehicles, high-end equipment and other emerging industries, and compressed biscuits, a fresh change process from corn to popcorn and then to compressed biscuits, Yangquanhong compares his two representative achievements: graphene low-temperature negative pressure cleavage technology and graphene hydrogel densification shrinkage technology. In another picture, yangquanhong drew the design process of the conductive model of the conductive agent from a bowl of "pimple soup" to a bowl of "noodle soup"

according to yangquanhong, taking the "grounded" route can not only make scientific research more interesting, but also make the team gain more

after the results were released, yangquanhong became more busy. He was invited to make reports everywhere and spread the "local atmosphere" of scientific research to more people

for the future, yangquanhong hopes that graphene research can do things that carbon materials "can't do well" and "can't do well", starting from solving the application bottleneck that traditional carbon materials can't solve, and looking for the killer application of graphene
