Does all-solid lithium batteries can break the "naked war" situation in battery companies?

Scientific research is sometimes very simple, not as deep as you think. What scientists need to do is to find the real academic problems from daily life and 'poke through the window', so as to open a window and see the further scenery.

In April, the begonias on the campus were in full bloom, and the scientific research career of Yang quanhong, professor of the school of chemical engineering of tianjin university and winner of the national science foundation for outstanding youth, also bloomed like a flower.

Recently, three of his papers have been published in a series in advanced energy materials, a leading journal in the energy field. In January he first proposed a "sulphur template" that would make lithium-ion batteries smaller. The results were published online in nature communications.

"It's just a small step." Yang quanhong was interviewed by science and technology daily on April 12. Talking about his research results, Yang quanhong appears low-key and pragmatic. Behind the plain, is the "carbon" researchers more than 20 years of dedication and pay.

In the field of energy storage, a number of internationally recognized research

Ability is the first impression that Yang quanhong gives a person. The 45-year-old's research interests include carbon nanomaterials and new battery materials. After graduating from the department of applied chemistry of tianjin university in 1994, Yang quanhong entered the shanxi coal chemistry research institute of the Chinese academy of sciences and completed her postgraduate and doctoral studies. It was during graduate school that he became fascinated with carbon materials.

Since then, from the Chinese academy of sciences institute of metal, the French scientific research center, tohoku university and the university of Southampton in England, until the return to his Alma mater, tianjin university in 2006 set up their own research team, he never left his passion for "carbon", almost all the energy and enthusiasm into high volume energy density energy storage devices and the design of carbon electrode materials, and in the applications of graphene density energy storage has made a series of key technological breakthroughs. The results promise to make gadgets like cellphones and laptops lighter and thinner.

To get smaller, capacity, higher energy storage devices, his team from the strategy, methods, materials, electrode, device and so on five aspects proposed the design principle of high volume energy density energy storage devices, which laid a foundation for practical application of carbon nanomaterials, strongly promote the practical application of new electrochemical energy storage device based on carbon nanotubes materials process. These research results have been published in important international academic journals, has been recognized by the industry.

Take the "down to earth" route and draw results on the poster

"Basic research has to produce useful results and tell interesting stories." This is what Yang quanhong often says.

Back in 2015, Yang quanhong was invited to publish a popular science article "how dreams come true" in People's Daily, introducing the application prospect and industrialization of graphene.

In Yang's opinion, scientific research is sometimes simple and not as profound as people think. What scientists need to do is to discover the real academic problems in daily life and "poke through the window", so as to open a window to see further scenery.

"Grounding" is one of the characteristics of Yang quanhong's scientific research work. In the corridor of the team lab, there are posters designed by Yang quanhong, two of which are particularly vivid.

In one picture, corn, popcorn and compressed biscuit are shown. The vivid process of change from corn to popcorn to compressed biscuit is used by Yang quanhong to compare his two representative achievements: low temperature negative pressure cleavage technology of graphene and dense shrinkage technology of graphene hydrogel. In another picture, Yang quanhong draws the design process of the conductive agent conductive model from a bowl of "pimple soup" to a bowl of "noodle soup".

In Yang's opinion, taking a "down-to-earth" approach not only makes scientific research more interesting, but also allows the team to gain more.

After the results came out, Yang quanhong also became busier. He was invited to give lectures and spread the science to more people.

For the future, Yang quanhong hopes that graphene research can do things that carbon materials "can't do well" and "can't do well". We should start from solving the application bottleneck that traditional carbon materials can't solve and look for the killer application of graphene.
